UDDEHOLM VANADIS® 10 SUPERCLEAN

Uddeholm Vanadis 10 SuperClean is a high vanadium alloyed powder

metallurgy tool steel offering a unique combination of an excellent abrasive

wear resistance in combination with a good chipping resistance. It is

manufactured according to the powder metallurgy process giving a very

low amount of non-metallic inclusions.

In tool making Uddeholm Vanadis 10 SuperClean offers a good

machinability and grindability together with a good dimensional stability

during heat treatment. It can normally be hardened to 60–65 HRC.

Critical toolsteel propertiesFor good tool performance• Correct hardness for the application• Very high wear resistance• Sufficient toughness to prevent premature

failure due to chipping/crack formation

High wear resistance is often associated withlow toughness and vice-versa. However, foroptimal tool performance both high wearresistance and toughness are essential in manycases.

Uddeholm Vanadis 10 SuperClean is apowder metallur-gical cold work tool steeloffering a combination of extremely high wearresistance and good toughness.

For toolmaking• Machinability• Heat treatment• Dimensional stability in heat treatment• Surface treatment

Toolmaking with highly alloyed steels meansthat machining and heat treatment are oftenmore of a problem than with the lower alloyedgrades. This can, of course, raise the cost oftoolmaking.

Due to the very carefully balanced alloyingand the powder metallurgical manufacturingroute, Uddeholm Vanadis 10 SuperClean has asimilar heat treatment procedure to the steelD2. One very big advantage with UddeholmVanadis 10 SuperClean is that the dimensionalstability after hardening and tempering is muchbetter than for the conventionally producedhigh performance cold work steels. This alsomeans that Uddeholm Vanadis 10 SuperCleanis a tool steel which is very suitable for CVDcoating.

ApplicationsUddeholm Vanadis 10 SuperClean is especiallysuitable for very long run tooling whereabrasive wear is the dominating problem. Itsvery good com-bination of extremely highwear resistance and ood toughness also makeUddeholm Vanadis 10 SuperClean an interest-ing alternative in applications where toolingmade of such materials as cemented carbidetends to chip or crack.

Heat treatmentSoft annealingProtect the steel and heat through to 900°C(1650°F). Cool in the furnace at 10°C (20°F)per hour to 650 °C (1200 °F), then freely in air.

Stress relievingAfter rough machining the tool should beheated through to 650°C (1200°F), holdingtime 2 hours. Cool slowly to 500°C (930°F),then freely in air.

HardeningPre-heating temperature: 600–700°C (1110–1290°F)Austenitizing temperature: 1020–1100°C (1870–2010°F)Holding time: 30 minutes.

Note: Holding time = time at hardening tem-perature after the tool is fully heated through.A holding time of less than 30 minutes willresult in loss of hardness.

The tool should be protected against decarburiza-tion and oxidation during hardening.

Quenching media• Forced air/gas• Vacuum furnace (gas overpressure 2–5 bar)• Martempering bath or fluidized bed at 500–

550°C (930–1020°F)• Martempering bath or fluidized bed at 200–

350°C (390–660°F) whereby 350°C (660°F)is preferred.

Note 1: Temper the tool as soon as its tem-perature reaches 50–70°C (120–160°F).

Note 2: In order to obtain the optimumproperties for the tool, the cooling rate shouldbe as fast as is concomitant with acceptabledistortion.

Note 3: Tools with sections >50 mm (2")should be quenched in forced air. Quenching instill air will result in loss of hardness.

Sub-zero treatmentTools requiring maximum dimensional stabilityin service can be sub-zero treated as follows:

Immediately after quenching, the tool shouldbe sub-zero treated to -70 to -80°C (-95 to-110°F), soaking time 1–3 hours, followed bytempering. The sub-zero treatment leads to areduction of retained austenite content. This,in turn, will result in a hardness increase of~1 HRC compared to not sub-zero treatedtools if low temperature tempering is used.For high temperature tempered tools therewill be no hardness increase and when refer-encing the normal tempering curves, a25 to 50°C (45 to 90°F) lower tempering tem-perature should be chosen to achieve the re-quired hardness.

Tools that are high temperature tempered,even without a sub-zero treatment, will have alow retained austenite content and in mostcases, a sufficient dimensional stability. How-ever, for high demands on dimensional stabilityin service it is also recommended to use a sub-zero treatment in combination with high tem-perature tempering.

NitridingNitriding produces a hard surface layer thatincreases wear resistance and reduces thetendency towards galling.

High temperature tempered UddeholmVanadis 10 SuperClean is normally temperedat 525°C (980°F). This means that the nitridingtemperature used should not exceed 500–525°C (930–980°F). Ion nitriding at a tempera-ture below the tempering temperature used ispreferred.

The surface hardness after nitriding isapproximately 1250 HV0,2 kg. The thickness ofthe layer should be chosen to suit the applica-tion in question.

The Powder Metallurgy processIn the powder metallurgy process nitrogen gas is used toatomise the melted steel into small droplets, or grains.Each of these small grains solidifies quickly and there islittle time for carbides to grow. These powder grains arethen compacted to an ingot in a hot isostatic press (HIP)at high temperature and pressure. The ingot is then rolledor forged to steel bars by conventional methods.

The resulting structure is completely homogeneoussteel with randomly distributed small carbides, harmlessas sites for crack initiation but still protecting the toolfrom wear.

Large slag inclusions can take the role as sites for crackinitiation instead. Therefore, the powder metallurgicalprocess has been further developed in stages to improvethe cleanliness of the steel. Powder steel from UddeholmTooling is today of the third generation and is consideredthe cleanest powder metallurgy tool steel product on themarket.

HEAT TREATMENT

Prior to delivery all of the different bar materials aresubjected to a heat treatment operation, either as softannealing or hardening and tempering. These operationsprovide the steel with the right balance between hardnessand toughness.

MACHINING

Before the material is finished and put into stock, we alsorough machine the bar profiles to required size and exacttolerances. In the lathe machining of large dimensions, thesteel bar rotates against a stationary cutting tool. In peel-ing of smaller dimensions, the cutting tools revolve aroundthe bar.

To safeguard our quality and guarantee the integrity ofthe tool steel we perform both surface- and ultrasonicinspections on all bars. We then remove the bar ends andany defects found during the inspection.
