Stainless Steel S82013-CD vs S82013 FORG-SA

Stainless Steel · S82013 temper comparison

S82013-CD and S82013 FORG-SA are two conditions of the same stainless steel grade, S82013: CD (cold drawn) versus FORG-SA (forged + Solution Annealed). The chemistry is identical, so every difference below comes from the condition. S82013-CD is the stronger of the two: yield strength 720 MPa (104 ksi) against 510 MPa (74 ksi) for S82013 FORG-SA, about 41% more; tensile strength follows at 880 MPa (128 ksi) vs 710 MPa (103 ksi). In exchange, S82013 FORG-SA is the more ductile: elongation 28% versus 18% for S82013-CD, and S82013-CD is harder (285 HB vs 225 HB). S82013 FORG-SA runs hotter in service (280°C vs 250°C continuous). On the shop floor, S82013 FORG-SA welds better (65 vs 55 out of 100).

S82013-CD vs S82013 FORG-SA — frequently asked

Is S82013-CD stronger than S82013 FORG-SA?

Yes. S82013-CD has a typical yield strength of 720 MPa (104 ksi) against 510 MPa (74 ksi) for S82013 FORG-SA — about 41% more. Tensile strength is 880 MPa (128 ksi) vs 710 MPa (103 ksi).

Which condition does FabDigit quote by default, CD or FORG-SA?

SA is the default S82013 condition in the FabDigit quote flow (neither CD nor FORG-SA). 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, S82013-CD or S82013 FORG-SA?

S82013-CD. Its machinability rates fair (40/100) against poor (34/100) for S82013 FORG-SA; for welding the order is S82013 FORG-SA first (good, 65/100) then S82013-CD (good, 55/100).
