Nickel Alloy Hastelloy C276 vs N06250
Nickel Alloy · grade comparison
Nickel Alloy Hastelloy C276 and N06250 are both nickel alloy grades. Both yield at about 360 MPa — strength does not separate them. Hastelloy C276 is harder — 194 HB against 180 HB for N06250 — which matters for wear surfaces and threads. On the shop floor, Hastelloy C276 sits in a lower cost tier (premium, $$$) than N06250 (high, $$$$).
Hastelloy C276Choose it when surface hardness matters, or when cost is the deciding factor.
Hastelloy C276 vs N06250: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all nickel alloy 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.
