Steel 8822 vs SCM415

Steel · grade comparison

Steel 8822 and SCM415 are both steel grades. Both yield at about 415 MPa — strength does not separate them. SCM415 runs hotter in service (400°C vs 200°C continuous). On the shop floor, SCM415 welds better (good vs fair), SCM415 forms better (good vs fair), and 8822 sits in a lower cost tier (budget, $) than SCM415 (standard, $$).
