ABSTRACT:
A nonmagnetic alloy steel containing by weight 5 to 30% Mn and 0.005 to 0.5% N (nitrogen), satisfying the condition that 100/9(C%+N%)+2(Mn%+Cu%) is more than 25% and containing at least one element to improve the machinability of the steel. Since the steel contains no Ni, the steel is inexpensive and can be used for bars for reinforcing concrete and bolts for civil engineering works and buildings.
