Product Description Grade 321 / 321H Stainless Steel Sheet UNS S32100Grade 321 / 321H Stainless Steel Sheet UNS S32100 overview321 stainless is a titanium stabilized grade commonly used for service in the 1000-1600°F temperature range. For service temperatures up to about 1600°F, a stabilizing treatment at 1550-1650°F, air cool, may be used to provide optimum resistance to intergranular corrosion and to polythionic acid stress corrosion cracking.321 stainless is readily welded by all common methods including submerged arc. Appropriate weld fillers are AWS ER347 bare wire and E347 covered electrodes. 321 stainless is similar in machinability to 304 stainless steel. It has a machinability rating of 45% relative to AISI B1112. Produc Forms : Sheet, plate , Coil , Strip .wire , Pipe, Tube ,Bar , Profile, Round, Flat, Square, HexagonalGrade 321 / 321H Stainless Steel Sheet UNS S32100 Specification and Dimension Ranges Grade 321/321HASTM A240, ASME SA240, BS EN 10028-7, BS EN 10088-2 and BS EN 10088-4EN 10088/2, EN 10088/4 and CE MarkingNACE MR 0175/ISO 15156 Certification Product Type321 Stainless Steel Sheet, 321 Stainless Steel PlateSpecificationASTM A240 / ASME SA240Tolerances (width / thickness)EN 10258/ DIN 59381)EN 10151 ASTM A240 Grade 321 StripsEN 10088 A240 Tp 321 stripsInternational StandardASTM A 480ASTM A 959ASME IIDEN ISO 9445EN ISO 18286EN 10051EN 10088-1ISO 15510DimensionsCold rolled 321 Stainless Steel Plate 0.5-6.4 mmHot rolled 321 Stainless Steel Plate 3.0-10.0 mmThickness0.1 to 100 mm ThkWidth10-2500mmLength2m, 2.44m, 3m, or as requiredFinishSATIN, 2B, 2D, BA NO (8), Cold rolled sheet (CR), Hot rolled plate (HR), No.1 finish hot rolled, 1D, No.4, BA, 8K, hairline, brush, mirror etc.HardnessSoft, Hard, Half Hard, Quarter Hard, Spring HardForms / ShapesPlate, Sheet, Coils, Foils, Strip, Flats, Clad Plate, Plain Sheet, Rolling Sheet, Rolling Plate, Flat Shim, Flat Sheet, Shim Sheet, Rolls, Blank (Circle), sheared, annealed, soft annealed, descaled, tread plate, Checker PlateOther Trade Name of 321 Stainless SheetSS 321, SUS 321, Inox 321, DIN 1.4541, UNS S32100, AISI 321, SAE 321 Sheet  Dimension Ranges: Width: 600mm~2030 mmThickness: 0.1~120.0 mmLength: 300~6000 mm , Max 18000 mm Surface Finish: No.1, 2B, BA, No.3, No.4, No.5, No.8, HL, Etching, SB, Ti-coating,color-coating ,embossing . Grade 321 / 321H Stainless Steel Sheet UNS S32100 ApplicationTypical applications include:Aircraft piston engine manifoldsExpansion jointsFirearms productionThermal oxidizersRefinery equipmentHigh temperature chemical process equipmentGrade 321 / 321H Stainless Steel Sheet UNS S32100 EquivalentAISI 321 equivalentsASTM A182 Grade F321ASTM A580 Grade S32100SAE 321ASTM A193 Grade B8T Class 1ASTM A632 Grade TP321JIS SUS321ASTM A193 Grade B8T Class 2ASTM A774 Grade TP321JIS SUS321TPYASTM A193 Grade B8TA Class 1AASTM A778 Grade TP321JIS SUS321TPASTM A194 Grade 8TASTM A813 Grade TP321JIS SUS321TFASTM A194 Grade 8TAASTM A814 Grade TP321JIS SUS321TBASTM A213 Grade TP321ASTM A943 Grade TP321EN X6CrNiTi18-10ASTM A240 Grade S32100ASTM A959 Grade S32100EN 1.4541ASTM A249 Grade TP321ASTM A965 Grade F321GOST 06Ch18N10TASTM A269 Grade TP321ASTM F2281 Grade S32100GOST 08X18H10TASTM A276 Grade S32100ASTM F2281 Type IIGOST 12X18H10TASTM A312 Grade TP321ASTM F593 Grade S32100GB 0Cr18Ni11TiASTM A313 Grade S32100ASTM F593 Grade Alloy Group 3UNS S32100ASTM A314 Grade S32100ASTM F594 Grade S32100DIN 1.4544ASTM A320 Grade B8T Class 1ASTM F594 Grade Alloy Group 3DIN 1.4544.9ASTM A320 Grade B8T Class 2ASTM F738M Grade S32100AFNOR 9160/C 63ASTM A320 Grade B8TA Class 1AASTM F738M Grade Alloy Group A2AFNOR 9160C201ASTM A336 Grade F321ASTM F836M Grade S32100AFNOR Z 10 CNT 18-11ASTM A336 Grade F321HASTM F836M Grade Alloy Group A4BS S524ASTM A358 Grade A240 Type 321DIN 1.4541BS S526ASTM A376 Grade TP321DIN X6CrNiTi18-10BS 2 S129ASTM A409 Grade TP321DIN X10CrNiMoTi18-10AISI S32100ASTM A473 Grade 321AFNOR Z6CNT18-10SAE S32100ASTM A479 Grade S32100BS 321S12EN FE-PA 13ASTM A511 Grade MT321BS 321S51EN 1.4544ASTM A554 Grade MT321UNI X6CrNiTi1811GOST 08Ch18N12TUNE F.3523SS 2337JIS SUSF321  UNE F.3553 Grade 321 / 321H Stainless Steel Sheet UNS S32100 Technical datasheetChemical CompositionChemical Composition (wt%) limits as specified in ASTM A240 and ASME SA240*.Element321Carbon0.08Chromium17.0-19.0Nickel9.0-12.0Manganese2.00Silicon0.75Nitrogen0.10Phosphorus0.045Sulfur0.030Titanium5(C+N) min / 0.70 max* Maximum, unless range is indicatedMechanical PropertiesMechanical property requirements for annealed product as specified in ASTM A240 and ASME SA240. Property321Yield Strength, min.
