Stainless Steel 305 Annealed vs 305 Cold Drawn

Stainless Steel · 305 temper comparison

305 Annealed and 305 Cold Drawn are two conditions of the same stainless steel grade, 305: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 305 Cold Drawn is the stronger of the two: yield strength 430 MPa (62.4 ksi) against 260 MPa (37.7 ksi) for 305 Annealed, about 65% more; tensile strength follows at 655 MPa (95 ksi) vs 585 MPa (84.8 ksi). In exchange, 305 Annealed is the more ductile: elongation 50% versus 32% for 305 Cold Drawn, and 305 Cold Drawn is harder (200 HB vs 150 HB).

305 AnnealedChoose it when the part is bent, formed or impact-loaded.

305 Cold DrawnChoose it when strength drives the design.
