Nickel Alloy MP35N-ANN vs MP35N-CW20

Nickel Alloy · MP35N temper comparison

MP35N-ANN and MP35N-CW20 are two conditions of the same nickel alloy grade, MP35N: ANN (annealed) versus CW20 (cold Worked ~20 %). The chemistry is identical, so every difference below comes from the condition. MP35N-CW20 is the stronger of the two: yield strength 900 MPa (131 ksi) against 415 MPa (60.2 ksi) for MP35N-ANN, about 117% more; tensile strength follows at 1,240 MPa (180 ksi) vs 950 MPa (138 ksi). In exchange, MP35N-ANN is the more ductile: elongation 65% versus 35% for MP35N-CW20, and MP35N-CW20 is harder (320 HB vs 210 HB). MP35N-ANN runs hotter in service (425°C vs 370°C continuous). On the shop floor, MP35N-ANN welds better (good vs fair).
