Stainless Steel 08Cr17Ti 1/2H vs 08Cr17Ti-CD

Stainless Steel · 08Cr17Ti temper comparison

08Cr17Ti 1/2H and 08Cr17Ti-CD are two conditions of the same stainless steel grade, 08Cr17Ti: 1/2H (half hard) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 08Cr17Ti 1/2H is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 430 MPa (62.4 ksi) for 08Cr17Ti-CD, about 30% more; tensile strength follows at 640 MPa (92.8 ksi) vs 560 MPa (81.2 ksi). In exchange, 08Cr17Ti-CD is the more ductile: elongation 18% versus 9% for 08Cr17Ti 1/2H, and 08Cr17Ti 1/2H is harder (230 HB vs 190 HB).

08Cr17Ti 1/2HChoose it when strength drives the design.

08Cr17Ti-CDChoose it when the part is bent, formed or impact-loaded.

08Cr17Ti 1/2H vs 08Cr17Ti-CD — frequently asked

Is 08Cr17Ti 1/2H stronger than 08Cr17Ti-CD?

Yes. 08Cr17Ti 1/2H has a typical yield strength of 560 MPa (81.2 ksi) against 430 MPa (62.4 ksi) for 08Cr17Ti-CD — about 30% more. Tensile strength is 640 MPa (92.8 ksi) vs 560 MPa (81.2 ksi).

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

Annealed is the default 08Cr17Ti 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.

When should I choose 08Cr17Ti 1/2H over 08Cr17Ti-CD?

Pick 08Cr17Ti 1/2H when strength drives the design. Pick 08Cr17Ti-CD when the part is bent, formed or impact-loaded.
