Stainless Steel 436-1/2 Hard vs 436 Cold Drawn

Stainless Steel · 436 temper comparison

436-1/2 Hard and 436 Cold Drawn are two conditions of the same stainless steel grade, 436: 1/2 Hard (half hard) versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 436-1/2 Hard is the stronger of the two: yield strength 585 MPa (84.8 ksi) against 550 MPa (79.8 ksi) for 436 Cold Drawn, about 6% more; tensile strength follows at 725 MPa (105 ksi) vs 655 MPa (95 ksi). In exchange, 436 Cold Drawn is the more ductile: elongation 14% versus 8% for 436-1/2 Hard, and 436-1/2 Hard is harder (240 HB vs 210 HB). 436 Cold Drawn runs hotter in service (425°C vs 315°C continuous). On the shop floor, 436 Cold Drawn machines more easily (good vs fair).

436-1/2 HardChoose it when strength drives the design.

436 Cold DrawnChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
