A high-manganese, non-magnetic steel having excellent weldability and machinability and suitable for use in the structural parts of electrical equipment or nuclear fusion equipment consisting essentially of (% by weight): -carbon 0.55-0.80 -silicon 0.1-1.2 -manganese 10.0-14.5 -nickel 0.3-3.0 -chromium 0.5-3.6 -nitrogen 0.01-0.2 - balance iron and inevitable impurities. The steel may further contain at least one element of 0.01 to 1.0% of molybdenum, 0.01 to 0.5% of vanadium, 0.01 to 0.5% of niobium, 0.005 to 0.5% of titanium, 0.01 to 1.0% of zirconium, 0.0007 to 0.005% of calcium, 0.01 to 0.15% of sulfur, 0.03 to 0.2% of selenium, 0.03 to 0.2% of lead, and 0.01 to 0.8% of tin. |
