Stainless Steel SUS317J1 1/2H vs SUS317J1-CD

Stainless Steel · SUS317J1 temper comparison

SUS317J1 1/2H and SUS317J1-CD are two conditions of the same stainless steel grade, SUS317J1: 1/2H (half hard) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. SUS317J1 1/2H is the stronger of the two: yield strength 760 MPa (110 ksi) against 480 MPa (69.6 ksi) for SUS317J1-CD, about 58% more; tensile strength follows at 1,030 MPa (149 ksi) vs 700 MPa (102 ksi). In exchange, SUS317J1-CD is the more ductile: elongation 30% versus 10% for SUS317J1 1/2H, and SUS317J1 1/2H is harder (300 HB vs 210 HB). SUS317J1-CD runs hotter in service (450°C vs 350°C continuous). On the shop floor, SUS317J1-CD welds better (very good vs good).

SUS317J1 1/2H vs SUS317J1-CD — frequently asked

Is SUS317J1 1/2H stronger than SUS317J1-CD?

Yes. SUS317J1 1/2H has a typical yield strength of 760 MPa (110 ksi) against 480 MPa (69.6 ksi) for SUS317J1-CD — about 58% more. Tensile strength is 1,030 MPa (149 ksi) vs 700 MPa (102 ksi).

Which condition does FabDigit quote by default, 1/2H or CD?

ANN is the default SUS317J1 condition in the FabDigit quote flow (neither 1/2H nor CD). 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, SUS317J1 1/2H or SUS317J1-CD?

SUS317J1-CD. Its machinability rates fair (36/100) against poor (28/100) for SUS317J1 1/2H; for welding the order is SUS317J1-CD first (very good, 75/100) then SUS317J1 1/2H (good, 65/100).
