Nickel 201-ANN vs Nickel 201-H24

Nickel Alloy · Nickel 201 temper comparison

Nickel 201-ANN and Nickel 201-H24 are two conditions of the same nickel alloy grade, Nickel 201: ANN (annealed) versus H24 (strain hardened and partially annealed, half hard). The chemistry is identical, so every difference below comes from the condition. Nickel 201-H24 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 105 MPa (15.2 ksi) for Nickel 201-ANN, about 3.6 times as much; tensile strength follows at 510 MPa (74 ksi) vs 415 MPa (60.2 ksi). In exchange, Nickel 201-ANN is the more ductile: elongation 47% versus 15% for Nickel 201-H24, and Nickel 201-H24 is harder (160 HB vs 90 HB). Nickel 201-ANN runs hotter in service (650°C vs 315°C continuous). On the shop floor, Nickel 201-H24 machines more easily (fair vs poor).

Nickel 201-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

Nickel 201-H24Choose it when strength drives the design, or when the part is machined in volume.
