Stainless Steel 1.4762 vs 430

Stainless Steel · grade comparison

Stainless Steel 1.4762 and 430 are both stainless steel grades. 1.4762 is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 310 MPa (45 ksi) for 430, about 6% more; tensile strength follows at 580 MPa (84.1 ksi) vs 500 MPa (72.5 ksi). In exchange, 430 is the more ductile: elongation 30% versus 18% for 1.4762, and 1.4762 is harder (195 HB vs 155 HB). 1.4762 is lighter (7.15 g/cm³ vs 7.7 g/cm³ for 430) and 1.4762 runs hotter in service (1,150°C vs 815°C continuous). On the shop floor, 430 machines more easily (50 vs 40 out of 100), 430 welds better (good vs fair), and 430 sits in a lower cost tier (standard, $$) than 1.4762 (premium, $$$).

1.4762Choose it when strength drives the design, or when weight is the constraint.

430Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
