Stainless Steel Alloy 20 vs N08026

Stainless Steel · grade comparison

Stainless Steel Alloy 20 and N08026 are both stainless steel grades. Both yield at about 310 MPa — strength does not separate them. N08026 is the more ductile: elongation 45% versus 40% for Alloy 20, and N08026 is harder (170 HB vs 160 HB). On the shop floor, Alloy 20 machines more easily (fair vs poor) and N08026 sits in a lower cost tier (high, $$$$) than Alloy 20 (specialty, $$$$$).

Alloy 20Choose it when the part is machined in volume.

N08026Choose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
