Nickel Alloy Alloy 42-H vs Alloy 42-H14

Nickel Alloy · Alloy 42 temper comparison

Alloy 42-H and Alloy 42-H14 are two conditions of the same nickel alloy grade, Alloy 42: H (hardened) versus H14 (strain hardened, half hard). The chemistry is identical, so every difference below comes from the condition. Alloy 42-H is the stronger of the two: yield strength 720 MPa (104 ksi) against 480 MPa (69.6 ksi) for Alloy 42-H14, about 50% more; tensile strength follows at 800 MPa (116 ksi) vs 620 MPa (89.9 ksi). In exchange, Alloy 42-H14 is the more ductile: elongation 15% versus 3% for Alloy 42-H, and Alloy 42-H is harder (247 HB vs 185 HB). Alloy 42-H14 runs hotter in service (350°C vs 300°C continuous).
