Stainless Steel 1.4983 vs 301

Stainless Steel · grade comparison

Stainless Steel 1.4983 and 301 are both stainless steel grades. 301 is the stronger of the two: yield strength 570 MPa (82.7 ksi) against 265 MPa (38.4 ksi) for 1.4983, about 115% more; tensile strength follows at 900 MPa (131 ksi) vs 590 MPa (85.6 ksi). In exchange, 1.4983 is the more ductile: elongation 40% versus 25% for 301, and 301 is harder (270 HB vs 170 HB). 1.4983 runs hotter in service (650°C vs 425°C continuous). On the shop floor, 301 sits in a lower cost tier (premium, $$$) than 1.4983 (high, $$$$).

1.4983Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

301Choose it when strength drives the design, or when cost is the deciding factor.
