Stainless Steel 1.4597 vs 301

Stainless Steel · grade comparison

Stainless Steel 1.4597 and 301 are both stainless steel grades. 301 is the stronger of the two: yield strength 570 MPa (82.7 ksi) against 340 MPa (49.3 ksi) for 1.4597, about 68% more; tensile strength follows at 900 MPa (131 ksi) vs 720 MPa (104 ksi). In exchange, 1.4597 is the more ductile: elongation 50% versus 25% for 301, and 301 is harder (270 HB vs 195 HB). 1.4597 runs hotter in service (760°C vs 425°C continuous). On the shop floor, 1.4597 sits in a lower cost tier (budget, $) than 301 (premium, $$$).

1.4597Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

301Choose it when strength drives the design.
