A non-magnetic steel material suitable for use in various steel and concrete structures such as magnetic floating high-speed railways, nuclear fusion facilities and marine structrures and appliances where non-magnetic properties are required. The steel composition contain (by weight): C: not more than 1.0% Si: not more than 0.25% Mn: not more than 2.0% Al: more than 20.0 to 37.3% P: not more than 0.015% S: not more than 0.005% Cr: more than 5.5 to 15.0% and may further contain at least one of Ti, V, Nb, W, Co, Mo and B in an amount ranging from 0.01 to 0.5% for the elements other than B, and in an amount ranging from 0.0001 to 0.005% for B, and at least one of Cu and Ni in an amount ranging from 0.1 to 5.5%.
