Stainless Steel 1.4592 vs 430

Stainless Steel · grade comparison

Stainless Steel 1.4592 and 430 are both stainless steel grades. 1.4592 is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 310 MPa (45 ksi) for 430, about 55% more; tensile strength follows at 600 MPa (87 ksi) vs 500 MPa (72.5 ksi). In exchange, 430 is the more ductile: elongation 30% versus 25% for 1.4592, and 1.4592 is harder (185 HB vs 155 HB). 430 runs hotter in service (815°C vs 300°C continuous) and 430 conducts heat better (26 W/m·K vs 17 W/m·K). On the shop floor, 430 machines more easily (50 vs 40 out of 100) and 430 sits in a lower cost tier (standard, $$) than 1.4592 (high, $$$$).
