Stainless Steel 1.4516 vs 430

Stainless Steel · grade comparison

Stainless Steel 1.4516 and 430 are both stainless steel grades. Both yield at about 320 MPa — strength does not separate them. 430 is the more ductile: elongation 30% versus 26% for 1.4516. 1.4516 is stiffer (220 GPa vs 200 GPa) and 430 runs hotter in service (815°C vs 650°C continuous). On the shop floor, 1.4516 welds better (very good vs good).

1.4516Choose it when it will be welded.

430Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
