Stainless Steel 1.4592 vs 405

Stainless Steel · grade comparison

Stainless Steel 1.4592 and 405 are both stainless steel grades. 1.4592 is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 280 MPa (40.6 ksi) for 405, about 71% more; tensile strength follows at 600 MPa (87 ksi) vs 480 MPa (69.6 ksi). In exchange, 405 is the more ductile: elongation 28% versus 25% for 1.4592, and 1.4592 is harder (185 HB vs 155 HB). 405 runs hotter in service (705°C vs 300°C continuous) and 405 conducts heat better (27 W/m·K vs 17 W/m·K). On the shop floor, 405 machines more easily (good vs fair), 405 welds better (very good vs good), and 405 sits in a lower cost tier (premium, $$$) than 1.4592 (high, $$$$).
