High manganese nonmagnetic steel having excellent machinability

摘要

The nonmagnetic alloy consists of 0.22-0.30% by weight of carbon, 22-28% by weight of manganese, up to 4% by weight of silicon, 0.030-0.10% by weight of sulphur, 0.001-0.008% by weight of calcium, 0.001-0.008% by weight of sol.Al and the balance of iron. If desired, either one or both of up to 2.0% by weight of chromium and up to 2.0% by weight of vanadium may be incorporated.
