Quality

A quality product, such as stainless steeltubular wire, begins with quality manufac-turing. The SelectAlloy stainless products aremanufactured under a quality systemcertified to ISO 9001:2000. In addition,Select-Arc’s quality system has been certifiedby ABS, CWB, NAVSEA, Lloyd’s Registry andDNV. Meeting all these requirements is noeasy feat, but Select-Arc’s systems and peopleare up to the task. The highest quality stain-less steel electrodes can only be made usingthe highest quality raw materials. All of thecomponents, such as strip, minerals, alloypowders and fluxing agents, are procuredusing rigorous purchasing standards. Uponarrival at Select-Arc, these materials areinspected and scrutinized to assure compli-ance with all technical requirements. The rawmaterials are then converted to tubularwelding wire using the most exacting manu-facturing techniques and in-process checks.Nothing is left to chance; strip dimensions,

Technology

The world of stainless steel welding typicallyrequires some combination of productperformance, deposit composition anddeposit cosmetics. The specific applicationwill determine the most critical characteris-tic resulting in the selection of the specificgrade. As an example, Austenitic stainlesssteel is chosen for its corrosion resistance andmechanical properties. More specifically,there are grades of austenitic stainless steelwhich are resistant to various degrees ofcorrosive media while other grades offerimproved corrosion resistance at elevatedtemperatures.

The same breadth of selection is availablewhen considering mechanical properties. Anexample would be the Austenitic grades abil-ity to provide excellent CVN impact proper-ties at subzero temperatures. However,performance characteristics such as coldworking may decrease the lower temperatureCVN properties and should be consideredwhen selecting an alloy.

When welding these materials, the weld de-posit must conform to the same propertiesand performance as the base material. TheSelectAlloyTM series of Austenitic flux coredand metal cored electrodes are manufacturedto meet the exacting requirements of the AWSA5.22 and A5.9 documents, respectively. The308 and 308L alloys are designed to weldthe standard “18-8” grades such as 304stainless steels. The 309 and 309L classesprovide enhanced heat resistance with addi-tional Cr and Ni alloying, and 316 and 316Lclasses are used for applications requiringhigher corrosion resistance. Other grades canbe designed to meet specific requirements byworking through the Select-Arc sales andapplication groups.

The ferritic stainless steel grades are used forapplications requiring corrosion resistancealong with moderate heat while the marten-sitic grades provide harder deposits for wearresistance. Select-Arc offers a variety offerritic metal cored wires used for weldingexhaust components, some offering theTitanium stabilization for smoother opera-tion, while Niobium provides improved welddeposits for materials with traces of oil orother contaminants. The wide selection ofSelect-Arc grades allows manufacturers toselect the proper product to match their basematerial and application.

Martensitic stainless steel products are offeredin both metal cored and flux cored wires forthe power generation industry, where theseproducts are typically utilized on 410 alloyssuch as turbine blades and forgings. Addi-tional corrosion and pitting resistance are

fill percentages, alloy mix consistency, fin-ished diameter and other process keys arechecked continually and held to very stricttolerances. Finally, the finished wire is takento the weld lab for final inspection, wherethe arc characteristics, bead cosmetics andslag removal are evaluated and must conformto the standards established during thedevelopment of the electrode. Prior to ship-ment, a chemical analysis of the welddeposit is performed for each mix ofproduct to ensure compliance with AWS andinternal standards.

It takes effort, discipline and adherence toprocedures to manufacture high quality,stainless steel tubular electrodes on a con-sistent basis. This is what Select-Arc does;every mix, every day. This dedication toexcellence is not a sometime thing, it is aconstant determination to make the bestproduct in the industry. The SelectAlloy lineof electrodes delivers; it delivers excellentfeedability, superb welding characteristics,consistent deposit chemistry and the bestoverall performance in the marketplace.

Productivity

In the manufacturing business, productivityis the key to profitability. When fabricatingstainless steel, welding with coveredelectrodes or solid wire will not maximizeproductivity. Stick welding has very lowdeposition rates due to process limitationsand results in reduced deposition efficiencydue to “stub loss”. The deposition rates ofsolid wire are limited when welding out-of-position unless expensive pulsed powersupplies and gases are used.

SelectAlloy flux cored electrodes are theperfect solution to the problem of how toincrease productivity and reduce weldingcosts. The higher deposition rates shownbelow indicate the productivity improve-ments that tubular wires can provide todramatically reduce overall welding costs.

least, the elevated temperature propertiesof the austenitic grades are quite exem-plary, as the higher chromium and nickelcontents help improve creep resistance andprevent oxidation and scaling.

Ferritic stainless steels are basically chro-mium-bearing alloys and have a bodycentered cubic (bcc) crystal structure.These are ferromagnetic materials whichexhibit good strength and ductility at roomtemperature, but have poor strength atelevated temperatures compared to theaustenitic grades. Chromium contentranges from 10.5-30%. In the case ofexhaust system, or muffler, grades, addi-tions of titanium or niobium may beemployed to stabilize the microstructureduring the heating and cooling process.The 400 series of ferritic alloys is usedextensively in the fabrication of exhaustsystem components, as they are lessexpensive than the austenitic grades, arequite formable and have good corrosionresistance.

Martensitic stainless steels are alloyed withchromium and carbon, and form a dis-torted body centered cubic (bcc) crystalstructure when hardened. These materialsare magnetic and resistant to only mildlycorrosive environments. The chromiumrange of these alloys is normally 10.5-18%and the carbon may exceed 1.20%. Thehigher carbon contents are usually usedfor applications requiring high hardnesses,such as knife edges. Nickel may be addedto impart extra corrosion resistance to thelower carbon grades, for applications suchas blades and vanes in power generationequipment. The combination of nickel andmolybdenum ensure the transformation tomartensite and bolster the pitting resis-tance along with corrosion resistance.

Duplex stainless steels contain a mixedmicrostructure of bcc ferrite and fccaustenite. These alloys normally containan equal amount of each, although theexact amount of each phase is determinedby composition and heat treatment.Chromium and nickel are the principalalloying agents, but elements such asnitrogen, molybdenum, copper and sili-con may be added for compositioncontrol and corrosion resistance. Duplexstainless steels have higher tensile and yieldstrengths than the austenitic types, as wellas improved resistance to stress corrosioncracking. The higher strength levels alsoprovide greater resistance to distortionduring welding. The toughness of thesematerials is between that of the austeniticand ferritic types.

The smooth bead contour, easy peelingslag and minimal spatter reduce slagremoval and grinding costs after welding,further reducing costs. Finally, the closelycontrolled weld deposit compositions andweld metal soundness provided by theSelectAlloy tubular wires eliminate theneed for rework of welds, providing addi-tional savings.

The Select series of ferritic stainless steel,metal cored electrodes offers the same pro-ductivity advantages as the austeniticflux cored, but in a somewhat differentmanner. This product type offers the ad-vantages of a solid wire, such as no slag toclean, with the productivity advantages ofa tubular wire, such as higher depositionrates, the ability to bridge gaps, and fastertravel speeds than solid wire. Difficult toweld components, such as exhaust systemswith poor fit up, can be welded quiteefficiently with the 400-series metal coredelectrodes. There is also the advantageof less spatter than solid wire and lesssubsurface porosity, translating into sub-stantial cost savings by not grindingspatter off the surface and not reworkingor repairing welds.

Metallurgy

Stainless steel alloys can be divided intofive groups; austenitic, ferritic, martensi-tic, duplex (ferritic-austenitic) and precipi-tation hardening.

Austenitic stainless steels are generouslyalloyed; they typically contain from 16-26% chromium and up to 35% nickel.Their crystal structure is face centered cu-bic (fcc) and they are not magnetic in theannealed condition. These materials workharden rapidly when cold worked andbecome ferromagnetic in the cold workedcondition. Austenitic stainless steelsproduce good charpy v-notch toughnessvalues at subzero, and cryogenic, tempera-tures, but the values will decline formaterial in the cold worked condition andwill vary by the amount of cold working.Corrosion resistance is dependent on manyfactors, including the in-service corrosiveenvironment, however, the chromium andnickel contents largely dictate the alloyperformance. Chromium in the range of17-20% or higher increases the passiva-tion properties of the material, which formsthe protective film. Nickel stabilizes theaustenite, but starts to decrease the resis-tance to stress corrosion cracking (SCC)up to the 8-10% range; beyond that theresistance to SCC starts to increase andpeaks at about 30% nickel. Last, but not

Precipitation hardening stainless steels areprincipally alloyed with chromium andnickel and contain precipitation hardeningelements such as copper, aluminum ortitanium. In the annealed condition, thesegrades may be either austenitic ormartensitic. The annealed, austenitic micro-structures can be transformed to martensiteby conditioning heat treatments, sometimesat subzero temperatures. In most cases, thesealloys attain high strength by precipitationhardening of the martensitic phase.
