Steel 5CrMnMo vs H10

Steel · grade comparison

Steel 5CrMnMo and H10 are both steel grades. Both yield at about 500 MPa — strength does not separate them. H10 is the more ductile: elongation 22% versus 18% for 5CrMnMo. H10 runs hotter in service (500°C vs 400°C continuous) and 5CrMnMo conducts heat better (34 W/m·K vs 30 W/m·K). On the shop floor, H10 welds better (45 vs 35 out of 100) and 5CrMnMo sits in a lower cost tier (budget, $) than H10 (premium, $$$).

5CrMnMoChoose it when cost is the deciding factor.

H10Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
