Stainless Steel 330 vs N08026

Stainless Steel · grade comparison

Stainless Steel 330 and N08026 are both stainless steel grades. N08026 is the stronger of the two: yield strength 310 MPa (45 ksi) against 270 MPa (39.2 ksi) for 330, about 15% more; tensile strength follows at 620 MPa (89.9 ksi) vs 585 MPa (84.8 ksi). N08026 is harder — 170 HB against 150 HB for 330 — which matters for wear surfaces and threads. 330 runs hotter in service (1,150°C vs 500°C continuous). On the shop floor, N08026 welds better (very good vs good) and N08026 sits in a lower cost tier (high, $$$$) than 330 (specialty, $$$$$).
