Stainless Steel 1.4886 vs 330
Stainless Steel · grade comparison
Stainless Steel 1.4886 and 330 are both stainless steel grades. Both yield at about 260 MPa — strength does not separate them. 1.4886 is harder — 160 HB against 150 HB for 330 — which matters for wear surfaces and threads. On the shop floor, 1.4886 welds better (very good vs good) and 1.4886 sits in a lower cost tier (high, $$$$) than 330 (specialty, $$$$$).
1.4886Choose it when surface hardness matters, or when it will be welded.
1.4886 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.
