Remanit® 4000

* Data to EN 10088

Depending on the intended use and as-delivered condition (annealed / quenched and tempered),it must be checked whether repeated heat treatment is necessary. The annealing colours or scaling occurring during hot forming or welding impair the corrosion resistance. They must be removed by pickling, grinding or sand-blasting (iron-free!).Metal-cutting machining is the same as that for plain carbon steel grades of corresponding strength. REMANIT 4000 can be polished.

Processing

Material number

Notes on use REMANIT 4000 is used as apparatus construction steel, particularly in cracking installations in theoil industry, owing to its good resistance to hydrogen and hydrogen sulphide. REMANIT 4000 is also suitable for welded parts in water turbine and hydroelectric station construction.A smoothed (industrially polished) and residue-free surface is necessary in order to achieve optimumcorrosion resistance of this chromium steel grade.The material displays higher resistance in quenched and tempered condition than in annealed condition.

Remanit® 4006

* Data to EN 10088

Processing REMANIT 4006 is primarily supplied in quenched and tempered condition QT 650. It can also be set to other tensilestrengths. It must be borne in mind in this context that the temperature range between 425 and 525 °C must be avoidedowing to embrittlement at 475 °C.The steel should preferably be formed in heated condition (100 to 300 °C). Depending on the degree of forming, hot forming at 700 to 800 °C may be necessary. Stress-relief annealing approx. 50 °C below the tempering temperature, but above 525 °C, is recommended in this context.The annealing colours or scaling occurring during hot forming or welding impair the corrosion resistance. They must beremoved by pickling, grinding or sand-blasting (iron-free!).Metal-cutting machining is the same as that for plain carbon steel grades of corresponding strength.REMANIT 4006 can be polished.

Remanit® 4122

Processing REMANIT 4122 is primarily used with a quenched and tempered strength of 750 to 950 N/mm2. In order to achieve higher strengths up to 1700 N/mm2, tempering temperatures up to max. 500 °C must be selected.REMANIT 4122 can be partially hardened; stress-relieving at 150 to 200 °C is necessary after hardening.Metal-cutting machining is the same as that for special structural steel grades of corresponding strength.REMANIT 4122 can be polished.

Material number

Notes on use Owing to the addition of molybdenum, REMANIT 4122 possesses broader chemical resistance compared to 17% chromium steel grades, although this only comes completely into effect with smoothed or industrially polished surfaces.Owing to its good wear and erosion resistance, REMANIT 4122 is used in pump shafts, fitting and compressor parts, as well as steam and water control valves and boat shafts for use in fresh water. Use in salt water is only possible with cathodic protection.

Remanit® 4301

* Data to EN 10088

Processing The possibilities for cold forming REMANIT 4301 are very good. The considerably greater strain hardening compared toplain steel grades demands correspondingly higher forming forces. In general, the regulations set out in AD Data SheetHP7/3 should be complied with during cold and hot forming, as well as any heat aftertreatment.The annealing colours or scaling occurring during hot forming or welding impair the corrosion resistance. They must beremoved by pickling, grinding or sand-blasting (iron-free!).Metal-cutting machining has to be performed with tools made of high-quality high-speed steel (good cooling necessary), orpreferably carbide cutting tools, owing to the strain hardening and the low thermal conductivity.The material versions REMANIT 4301 IM and REMANIT 4301 SUPER IM display better cutting properties owing to thespecific addition of sulphur or sulphur and calcium.REMANIT 4301 can be polished.

Material number

Notes on use Owing to its good corrosion resistance, cold formability and weldability,REMANIT 4301 is widely used in apparatus and tank construction, for fittings in equipment for the processing of food and tobacco goods,and in medical systems.REMANIT 4301 is resistant to intercrystalline corrosion duringcontinuous operation at up to 300 °C .

Remanit® 4303

Processing The nickel content of this steel grade - which is approx. 2% higher than that of REMANIT 4301 -results in higher austenite stability. The resultant considerable reduction in the tendency towards strainhardening permits better cold formability by means of cold heading or cold pressing,for example.The annealing colours or scaling occurring during hot forming or welding impair the corrosion resistance. They must be removed by pickling, grinding or sand-blasting (iron-free!).Metal-cutting machining has to be performed with tools made of high-quality, high-speed steel(good cooling necessary), or preferably carbide cutting tools.REMANIT 4303 can be polished.

Material number

Notes on use The main application of REMANIT 4303 is themanufacture of screws, nuts and cold-extruded parts,as this steel grade is particularly suitable for stronger cold forming.

Remanit® 4305

Processing REMANIT 4305 is processed almost exclusively by means of metal-cutting.As with other austenitic steel grades, tools made of high-quality, high-speedsteel or carbide cutting tools are necessary. Attention must be paid to good cooling.Owing to the addition of sulphur, short-brittle chips are obtained from REMANIT 4305 during metal-cutting, meaning that automatic machines can be used.REMANIT 4305 can be polished to a limited extent.

Material number

Notes on use The cutting properties of REMANIT 4305 are considerably improved by the addition of sulphur;this makes this material particularly suitable for the manufacture of turned parts on automatic machines.However, the addition of sulphur reduces the corrosion resistance.The corrosion resistance can be markedly improved whilst retainingthe cutting properties by adding titanium.Please consult us in this regard.

Soft annealing in the sense of ferrite formation is not possible.REMANIT 4418 is usually supplied in two tempering levels.During any heat treatment, it must be noted that, when cooling fromtemperatures above 600 °C, the formation of martensite does not startuntil below 200 °C and that it may not be completed at room temperature.It is thus recommendable to deep-freeze to approx. - 50 °C, or at least to store for severalhours at room temperature, before tempering.The temperature range between 420 and 550 °C should be avoided or passed through asquickly as possible owing to embrittlement at 475 °C.Metal-cutting machining is perfectly possible if the high strength is taken into account.

The application possibilities of REMANIT 4418 are characterised by its goodcorrosion behaviour, its high strength with good toughness properties down to- 60 °C and its reliable weldability. REMANIT 4418 is used for highly-stressed parts in fittings and pump construction,for compressors and turbines in hydroelectric stations, andfor general mechanical engineering parts for refrigerating systems.REMANIT 4418 is also used for ship shafts.

Remanit® 4429

The possibilities for cold forming REMANIT 4429 are very good. The considerably greater strain hardening compared to plain steel grades demands correspondingly higher forming forces.In general, the regulations set out in AD Data Sheet HP7/3 should be complied with during cold and hot forming, as wellas any heat aftertreatment.The annealing colours or scaling occurring during hot forming or welding impair the corrosion resistance. They must beremoved by pickling, grinding or sand-blasting (iron-free!).Metal-cutting machining has to be performed with tools made of high-quality, high-speed steel (good cooling necessary), orpreferably carbide cutting tools, owing to the strain hardening and the low thermal conductivity.REMANIT 4429 can be polished.

The resistance of REMANIT 4429 to intercrystalline corrosion, even in welded condition, is ensured by the low carboncontent. REMANIT 4429 is resistant to intercrystalline corrosion during continuous operation at up to 400 °C.While its corrosion resistance is comparable to that of REMANIT 4435, this material offers the advantage of higher designstrengths.REMANIT 4429 is used in textile finishing and the pharmaceutical industry, as well as in man-made fibre production andpulp and paper processing. Furthermore, REMANIT 4429 is also used for the production of artificial fertilisers. If resistanceto the Huey test is required, special analytical and process engineering measures may be necessary. REMANIT 4429meets the requirements of Basle Standard 2.

Remanit® 4462

REMANIT 4462 can be cold and hot formed.Renewed heat treatment is necessary after hot forming.Cold forming can be carried out at room temperature; heat treatment must also be carried out after cold forming of more than 10%. The tendency of this steel grade towards strain hardeningis lower than that of austenitic chromium-nickel steel grades, although it requires greater forming forces.A bright metallic surface, such as can be achieved by pickling, is a prerequisite for goodcorrosion resistance.Metal-cutting machining is possible in the range of parameters used for austenitic steel grades,although REMANIT 4462 displays a lesser tendency towards smearing.REMANIT 4462 can be polished.

Owing to its good mechanical properties and simultaneous high resistance to general corrosion, stress corrosion crackingand vibrational corrosion, REMANIT 4462 is suitable for many applications in the chemical and petrochemical industries, inseawater desalination plants and in offshore engineering, e.g. for acid gas pipelines and supporting structures.Material 1.4462 is authorised for pressure vessels in the temperature range between - 10 °C and + 280 °C (VdTÜVMaterial Data Sheet 418).

Remanit® 4542

* To EN 10088


If none of the heat treatment conditions named is expressly stated in the order, REMANIT 4542 is supplied in solution-annealed condition. Soft annealing in the sense of ferrite formation is not possible.During any heat treatment, it must be noted that, when cooling from temperatures above 600 °C, the formation ofmartensite does not start until below 200 °C and that it may not be completed at room temperature.It is thus recommendable to deep-freeze to approx. - 50 °C, or at least to store for several hours at room temperature,before ageing.REMANIT 4542 has good metal-cutting properties.The cutting properties are improved further by double ageing: 2 hours at 760 °C and 4 hours at 620 °C. The material must be solution-annealed and aged under defined conditions after machining.

REMANIT 4542 is used wherever high strengths and simultaneously good corrosion resistance are required.The possibility of setting different strengths uniformly and specifically by means of the various ageing treatments,even for cross sections of up to 200 mm, makes this steel grade suitable for processing into screws, spindlesand wheel, cover and hub disks.

The possibilities for cold forming REMANIT 4550 are very good. The considerably greater strain hardening compared to plain steel grades demands correspondingly higher forming forces.In general, the regulations set out in AD Data Sheet HP7/3 should be complied with during cold and hot forming, as wellas any heat aftertreatment.Stabilisation annealing at 900 to 920 °C with subsequent air cooling is permissible.The annealing colours or scaling occurring during hot forming or welding impair the corrosion resistance. They must beremoved by pickling, grinding or sand-blasting (iron-free!).Metal-cutting machining has to be performed with tools made of high-quality, high-speed steel (good cooling necessary), orpreferably carbide cutting tools, owing to the strain hardening and the low thermal conductivity.REMANIT 4550 can be polished.

Owing to the addition of niobium as a carbide former, REMANIT 4550 is resistant to intercrystalline corrosion, even inwelded condition, during continuous operation at up to 400 °C, regardless of its thickness and cross-section.REMANIT 4550 is preferably used in the construction of nuclear power stations.Certain ferrite contents and stabilisation ratios are used in order to increase the reliability of welds.

The possibilities for cold forming REMANIT 4563 are very good. The considerably greater strain hardening compared to plain steel grades demands correspondingly higher forming forces.The annealing colours or scaling occurring during hot forming or welding impair the corrosion resistance. They must beremoved by pickling, grinding or sand-blasting (iron-free!).Metal-cutting machining has to be performed with tools made of high-quality, high-speed steel (good cooling necessary), orpreferably carbide cutting tools, owing to the strain hardening and the low thermal conductivity.REMANIT 4563 can be polished.

The resistance of REMANIT 4563 to intercrystalline corrosion, even in welded condition, is ensured by the low carboncontent. REMANIT 4563 is resistant to intercrystalline corrosion during continuous operation at up to 400 °C.The high chromium, nickel and molybdenum contents afford REMANIT 4563 better resistance to media containing chloride,as well as oxidising and reducing acids. The addition of copper increases the resistance to sulphuric solutions. REMANIT4563 is a very stable austenite which is resistant to stress corrosion cracking.REMANIT 4563 is a material for particularly critical applications in the chemical industry, for rock phosphate digestion andthe manufacture and processing of sulphuric acid. Its high resistance to pitting makes it suitable for applications in marinesystems, such as seawater desalination plants or seawater-cooled heat exchangers, and as a material for pipestransporting acid gases.

REMANIT 4565 is a highly nitrogen-alloyed, fully austenitic special steel grade, which displays excellent corrosionresistance in a host of corrosive media, as well as great strength. The high nitrogen content results in a stable austeniticstructure, high strength and extraordinary resistance to pitting and crevice corrosion, in both quenched and weldedcondition.REMANIT 4565 is particularly recommended for use in the construction of chemical apparatus, in the pulp and paperindustry, and for the transport and storage of key chemicals. REMANIT 4565 is suitable for installations in flue-gasdesulphurisation and seawater treatment plants, as well as in fields with comparable requirements.The high resistance to chlorine-induced pitting and crevice corrosion permits use in the extraction and transport of crude oiland natural gas under both offshore and onshore conditions.

THERMAX 4713 is a heat-resistant ferritic steel grade with time-creep limit values which are considerably lower than thoseof austenitic steel grades. For this reason, it can only be used under moderate mechanical stresses. THERMAX 4713 isscale-resistant up to 800 °C in oxidising atmospheres.

Embrittlement due to ferrite grain growth also occurs when heating THERMAX 4762 to temperatures over approx. 950 °C.This embrittlement cannot be eliminated. Another area of brittleness is the temperature range between 400 and 550 °C(475 °C embrittlement). Lengthy heating or slow cooling in this temperature range should be avoided. This embrittlementcan be eliminated by briefly heating to temperatures between 700 and 800 °C. In the temperature range between 600 and900 °C, THERMAX 4762 displays a tendency towards ∑-phase embrittlement, meaning that the toughness properties aregreatly reduced after relatively long use in this temperature range. Therefore, THERMAX 4762 should not be used in thistemperature range. If embrittlement nonetheless occurs, it can be eliminated by heating to temperatures above 1000 °C.

In the critical temperature range between 600 and 900 °C, THERMAX 4841 displays a marked tendency towards ∑-phaseembrittlement, meaning that the toughness properties are greatly reduced after relatively long use in this temperaturerange. Therefore, THERMAX 4841 should not be used in this temperature range. If embrittlement nonetheless occurs, itcan be eliminated by heating to temperatures above 1000 °C.

The formability in cold and hot condition is excellent. The considerably greater strain hardening compared to plain steelgrades demands correspondingly higher forming forces.Metal-cutting machining has to be performed with tools made of high-quality, high-speed steel (good cooling necessary), orpreferably carbide cutting tools, owing to the strain hardening and the low thermal conductivity.The selection of relatively low cutting speeds and feed rates is recommended.

THERMAX 4845 is a heat-resistant austenitic steel grade which is characterised by good high-temperature strength atelevated temperatures. It can thus be used wherever relatively high mechanical stresses occur, in particular.THERMAX 4845 is scale-resistant to around 1050 °C in oxidising atmospheres. As an austenitic steel grade, THERMAX4845 is very slightly sensitive to SO2 and also to gases containing H2S at temperatures over 650 °C. It displays slightsensitivity to carbonising gases at temperatures above 900 °C.
