Nickel Alloy Haynes 230 vs Inconel 601

Nickel Alloy · grade comparison

Nickel Alloy Haynes 230 and Inconel 601 are both nickel alloy grades. Haynes 230 is the stronger of the two: yield strength 390 MPa (56.6 ksi) against 310 MPa (45 ksi) for Inconel 601, about 26% more; tensile strength follows at 870 MPa (126 ksi) vs 690 MPa (100 ksi). Haynes 230 is harder — 195 HB against 150 HB for Inconel 601 — which matters for wear surfaces and threads. Inconel 601 is lighter (8.11 g/cm³ vs 8.97 g/cm³ for Haynes 230) and Inconel 601 conducts heat better (11.2 W/m·K vs 8.9 W/m·K). On the shop floor, Inconel 601 machines more easily (28 vs 18 out of 100).

Haynes 230Choose it when strength drives the design, or when surface hardness matters.

Inconel 601Choose it when weight is the constraint, or when the part is machined in volume.

Haynes 230 vs Inconel 601 — frequently asked

Is Haynes 230 stronger than Inconel 601?

Yes. Haynes 230 has a typical yield strength of 390 MPa (56.6 ksi) against 310 MPa (45 ksi) for Inconel 601 — about 26% more. Tensile strength is 870 MPa (126 ksi) vs 690 MPa (100 ksi).

Which is cheaper, Haynes 230 or Inconel 601?

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 is easier to machine, Haynes 230 or Inconel 601?

Inconel 601, by a small margin. Both rate poor for machinability — 28/100 against 18/100 for Haynes 230.
