Stainless Steel 202-3/4 Hard vs 202 Cold Rolled

Stainless Steel · 202 temper comparison

202-3/4 Hard and 202 Cold Rolled are two conditions of the same stainless steel grade, 202: 3/4 Hard (three-quarter hard) versus Cold Rolled. The chemistry is identical, so every difference below comes from the condition. 202-3/4 Hard is the stronger of the two: yield strength 960 MPa (139 ksi) against 420 MPa (60.9 ksi) for 202 Cold Rolled, about 129% more; tensile strength follows at 1,240 MPa (180 ksi) vs 720 MPa (104 ksi). In exchange, 202 Cold Rolled is the more ductile: elongation 45% versus 10% for 202-3/4 Hard, and 202-3/4 Hard is harder (345 HB vs 215 HB). 202 Cold Rolled runs hotter in service (400°C vs 300°C continuous). On the shop floor, 202 Cold Rolled welds better (good vs fair).

202-3/4 Hard vs 202 Cold Rolled — frequently asked

Is 202-3/4 Hard stronger than 202 Cold Rolled?

Yes. 202-3/4 Hard has a typical yield strength of 960 MPa (139 ksi) against 420 MPa (60.9 ksi) for 202 Cold Rolled — about 129% more. Tensile strength is 1,240 MPa (180 ksi) vs 720 MPa (104 ksi).

Which condition does FabDigit quote by default, 3/4 Hard or Cold Rolled?

Annealed is the default 202 condition in the FabDigit quote flow (neither 3/4 Hard nor Cold Rolled). 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, 202-3/4 Hard or 202 Cold Rolled?

202 Cold Rolled. Its machinability rates fair (40/100) against poor (32/100) for 202-3/4 Hard; for welding the order is 202 Cold Rolled first (good, 65/100) then 202-3/4 Hard (fair, 50/100).
