Stainless Steel 330 vs N08024
Stainless Steel · grade comparison
Stainless Steel 330 and N08024 are both stainless steel grades. N08024 is the stronger of the two: yield strength 290 MPa (42.1 ksi) against 270 MPa (39.2 ksi) for 330, about 7% more; tensile strength follows at 620 MPa (89.9 ksi) vs 585 MPa (84.8 ksi). N08024 is harder — 180 HB against 150 HB for 330 — which matters for wear surfaces and threads. 330 runs hotter in service (1,150°C vs 425°C continuous). On the shop floor, N08024 welds better (very good vs good), N08024 forms better (very good vs good), and N08024 sits in a lower cost tier (high, $$$$) than 330 (specialty, $$$$$).
330Choose it when the part sees heat.
N08024Choose it when strength drives the design, or when surface hardness matters.
330 vs N08024: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
