Stainless Steel 330 vs N08535

Stainless Steel · grade comparison

Stainless Steel 330 and N08535 are both stainless steel grades. Both yield at about 270 MPa — strength does not separate them. N08535 is harder — 160 HB against 150 HB for 330 — which matters for wear surfaces and threads. 330 runs hotter in service (1,150°C vs 550°C continuous). On the shop floor, N08535 welds better (very good vs good) and N08535 sits in a lower cost tier (high, $$$$) than 330 (specialty, $$$$$).
