A non-magnetic steel composition suitable for use in various steel and concrete structures, particularly magnetic floating high-speed railways, nuclear fusion facilities and marine structures and appliances where non-magnetic property is required. The steel composition contains 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% Cr: more than 1.0 to 5.5% P: not more than 0.015% S: not more than 0.005% and may further contain at least one of Ti, V, Nb, W, Mo, and B in an amount ranging from 0.01 to 0.5%, in total, 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%, in total. |
