Stainless Steel S34565-CD vs S34565-F49

Stainless Steel · S34565 temper comparison

S34565-CD and S34565-F49 are two conditions of the same stainless steel grade, S34565: CD (cold drawn) versus F49 (forged and solution annealed). The chemistry is identical, so every difference below comes from the condition. S34565-CD is the stronger of the two: yield strength 700 MPa (102 ksi) against 450 MPa (65.3 ksi) for S34565-F49, about 56% more; tensile strength follows at 950 MPa (138 ksi) vs 830 MPa (120 ksi). In exchange, S34565-F49 is the more ductile: elongation 40% versus 25% for S34565-CD, and S34565-CD is harder (280 HB vs 215 HB).

S34565-CDChoose it when strength drives the design.

S34565-F49Choose it when the part is bent, formed or impact-loaded.
