Nickel Alloy IN-100 vs N-12M-1

Nickel Alloy · grade comparison

Nickel Alloy IN-100 and N-12M-1 are both nickel alloy grades. IN-100 is the stronger of the two: yield strength 855 MPa (124 ksi) against 370 MPa (53.7 ksi) for N-12M-1, about 131% more; tensile strength follows at 1,020 MPa (148 ksi) vs 585 MPa (84.8 ksi). In exchange, N-12M-1 is the more ductile: elongation 10% versus 9% for IN-100, and IN-100 is harder (375 HB vs 200 HB). IN-100 is lighter (7.75 g/cm³ vs 9.24 g/cm³ for N-12M-1) and IN-100 runs hotter in service (980°C vs 700°C continuous). On the shop floor, N-12M-1 machines more easily (poor vs not recommended) and N-12M-1 welds better (fair vs not recommended).

IN-100Choose it when strength drives the design, or when weight is the constraint.

N-12M-1Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

IN-100 vs N-12M-1 — frequently asked

Is IN-100 stronger than N-12M-1?

Yes. IN-100 has a typical yield strength of 855 MPa (124 ksi) against 370 MPa (53.7 ksi) for N-12M-1 — about 131% more. Tensile strength is 1,020 MPa (148 ksi) vs 585 MPa (84.8 ksi).

Which is cheaper, IN-100 or N-12M-1?

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, IN-100 or N-12M-1?

N-12M-1. Its machinability rates poor (20/100) against not recommended (10/100) for IN-100; for welding the order is N-12M-1 first (fair, 35/100) then IN-100 (not recommended, 5/100).
