Stainless Steel 153 MA vs 301

Stainless Steel · grade comparison

Stainless Steel 153 MA 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 153 MA, about 68% more; tensile strength follows at 900 MPa (131 ksi) vs 650 MPa (94.3 ksi). In exchange, 153 MA is the more ductile: elongation 45% versus 25% for 301, and 301 is harder (270 HB vs 190 HB). 153 MA runs hotter in service (1,000°C vs 425°C continuous) and 301 conducts electricity better (2.4 % IACS vs 2 % IACS). On the shop floor, 153 MA welds better (very good vs good) and 301 sits in a lower cost tier (premium, $$$) than 153 MA (high, $$$$).

153 MAChoose 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.
