Stainless Steel 330 vs N08332
Stainless Steel · grade comparison
Stainless Steel 330 and N08332 are both stainless steel grades. 330 is the stronger of the two: yield strength 270 MPa (39.2 ksi) against 250 MPa (36.3 ksi) for N08332, about 8% more. On the shop floor, N08332 sits in a lower cost tier (high, $$$$) than 330 (specialty, $$$$$).
330Choose it when strength drives the design.
N08332Choose it when cost is the deciding factor.
330 vs N08332: 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.
