Stainless Steel S41003 Cold Drawn vs S41003 Hardened

Stainless Steel · S41003 temper comparison

S41003 Cold Drawn and S41003 Hardened are two conditions of the same stainless steel grade, S41003: Cold Drawn versus Hardened. The chemistry is identical, so every difference below comes from the condition. S41003 Hardened is the stronger of the two: yield strength 700 MPa (102 ksi) against 520 MPa (75.4 ksi) for S41003 Cold Drawn, about 35% more; tensile strength follows at 950 MPa (138 ksi) vs 640 MPa (92.8 ksi). In exchange, S41003 Cold Drawn is the more ductile: elongation 15% versus 12% for S41003 Hardened, and S41003 Hardened is harder (310 HB vs 210 HB). S41003 Cold Drawn runs hotter in service (600°C vs 425°C continuous). On the shop floor, S41003 Cold Drawn machines more easily (good vs poor) and S41003 Cold Drawn welds better (very good vs fair).

S41003 Cold DrawnChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

S41003 HardenedChoose it when strength drives the design.

S41003 Cold Drawn vs S41003 Hardened — frequently asked

Is S41003 Hardened stronger than S41003 Cold Drawn?

Yes. S41003 Hardened has a typical yield strength of 700 MPa (102 ksi) against 520 MPa (75.4 ksi) for S41003 Cold Drawn — about 35% more. Tensile strength is 950 MPa (138 ksi) vs 640 MPa (92.8 ksi).

Which condition does FabDigit quote by default, Cold Drawn or Hardened?

Annealed is the default S41003 condition in the FabDigit quote flow (neither Cold Drawn nor Hardened). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

Which is easier to machine, S41003 Cold Drawn or S41003 Hardened?

S41003 Cold Drawn. Its machinability rates good (60/100) against poor (30/100) for S41003 Hardened; for welding the order is S41003 Cold Drawn first (very good, 70/100) then S41003 Hardened (fair, 50/100).
