High temperature annealing process of HPM75 non magnetic steel
HPM75 non-magnetic steel annealing temperature 870-890℃, holding 3-6h, furnace cooling below 500℃ out of air cooling. The hardness of HPM75 after annealing is 28-30HRC, and the microstructure is fine grain austenite + uniformly distributed granular carbide. High temperature annealing can improve the machinability of HPM75 steel.
