Stainless Steel 410 vs S42030

Stainless Steel · grade comparison

Stainless Steel 410 and S42030 are both stainless steel grades. S42030 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 310 MPa (45 ksi) for 410, about 23% more; tensile strength follows at 690 MPa (100 ksi) vs 517 MPa (75 ksi). In exchange, 410 is the more ductile: elongation 25% versus 22% for S42030, and S42030 is harder (210 HB vs 155 HB). On the shop floor, 410 machines more easily (good vs fair), 410 welds better (fair vs poor), and S42030 sits in a lower cost tier (standard, $$) than 410 (premium, $$$).

410Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

S42030Choose it when strength drives the design, or when cost is the deciding factor.
