Nickel Alloy Incoloy 800HT vs Inconel 600
Nickel Alloy · grade comparison
Nickel Alloy Incoloy 800HT and Inconel 600 are both nickel alloy grades. Inconel 600 is the stronger of the two: yield strength 255 MPa (37 ksi) against 240 MPa (34.8 ksi) for Incoloy 800HT, about 6% more; tensile strength follows at 620 MPa (89.9 ksi) vs 520 MPa (75.4 ksi). Inconel 600 is harder — 150 HB against 140 HB for Incoloy 800HT — which matters for wear surfaces and threads. Incoloy 800HT is lighter (7.94 g/cm³ vs 8.47 g/cm³ for Inconel 600) and Inconel 600 is stiffer (214 GPa vs 196 GPa).

Incoloy 800HT vs Inconel 600: 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.

Incoloy 800HT vs Inconel 600 — frequently asked
Is Inconel 600 stronger than Incoloy 800HT?
Yes. Inconel 600 has a typical yield strength of 255 MPa (37 ksi) against 240 MPa (34.8 ksi) for Incoloy 800HT — about 6% more. Tensile strength is 620 MPa (89.9 ksi) vs 520 MPa (75.4 ksi).
Which is cheaper, Incoloy 800HT or Inconel 600?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, Incoloy 800HT or Inconel 600?
Inconel 600. Its weldability rates very good (80/100) against very good (75/100) for Incoloy 800HT.
