Stainless Steel 2304 vs S82013

Stainless Steel · grade comparison

Stainless Steel 2304 and S82013 are both stainless steel grades. S82013 is the stronger of the two: yield strength 540 MPa (78.3 ksi) against 460 MPa (66.7 ksi) for 2304, about 17% more; tensile strength follows at 730 MPa (106 ksi) vs 680 MPa (98.6 ksi). 2304 is harder — 22 HRC against 20 HRC for S82013 — which matters for wear surfaces and threads. On the shop floor, S82013 sits in a lower cost tier (standard, $$) than 2304 (premium, $$$).

2304Choose it when surface hardness matters.

S82013Choose it when strength drives the design, or when cost is the deciding factor.
