Stainless Steel 301 vs 310HCb

Stainless Steel · grade comparison

Stainless Steel 301 and 310HCb are both stainless steel grades. 301 is the stronger of the two: yield strength 570 MPa (82.7 ksi) against 260 MPa (37.7 ksi) for 310HCb, about 119% more; tensile strength follows at 900 MPa (131 ksi) vs 590 MPa (85.6 ksi). In exchange, 310HCb is the more ductile: elongation 45% versus 25% for 301, and 301 is harder (270 HB vs 170 HB). 310HCb runs hotter in service (1,100°C vs 425°C continuous) and 301 conducts heat better (16.2 W/m·K vs 14.2 W/m·K). On the shop floor, 301 sits in a lower cost tier (premium, $$$) than 310HCb (high, $$$$).

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

310HCbChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
