Stainless Steel 1.4864 vs 330
Stainless Steel · grade comparison
Stainless Steel 1.4864 and 330 are both stainless steel grades. 330 is the stronger of the two: yield strength 270 MPa (39.2 ksi) against 255 MPa (37 ksi) for 1.4864, about 6% more. 330 runs hotter in service (1,150°C vs 1,050°C continuous). On the shop floor, 1.4864 sits in a lower cost tier (high, $$$$) than 330 (specialty, $$$$$).
1.4864Choose it when cost is the deciding factor.
330Choose it when strength drives the design, or when the part sees heat.
1.4864 vs 330: 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.
