Stainless Steel 310H-CD vs 310H-F310H

Stainless Steel · 310H temper comparison

310H-CD and 310H-F310H are two conditions of the same stainless steel grade, 310H: CD (cold drawn) versus F310H (forged + Annealed). The chemistry is identical, so every difference below comes from the condition. 310H-CD is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 260 MPa (37.7 ksi) for 310H-F310H, about 92% more; tensile strength follows at 760 MPa (110 ksi) vs 590 MPa (85.6 ksi). In exchange, 310H-F310H is the more ductile: elongation 42% versus 25% for 310H-CD, and 310H-CD is harder (240 HB vs 165 HB). 310H-F310H runs hotter in service (1,100°C vs 500°C continuous).

310H-CDChoose it when strength drives the design.

310H-F310HChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

310H-CD vs 310H-F310H — frequently asked

Is 310H-CD stronger than 310H-F310H?

Yes. 310H-CD has a typical yield strength of 500 MPa (72.5 ksi) against 260 MPa (37.7 ksi) for 310H-F310H — about 92% more. Tensile strength is 760 MPa (110 ksi) vs 590 MPa (85.6 ksi).

Which condition does FabDigit quote by default, CD or F310H?

Annealed is the default 310H condition in the FabDigit quote flow (neither CD nor F310H). 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 310H-CD over 310H-F310H?

Pick 310H-CD when strength drives the design. Pick 310H-F310H when the part is bent, formed or impact-loaded, or when the part sees heat.
