摘要： PURPOSE:To obtain a high-strength and non-magnetic steel excellent in the ductility and toughness which can keep the stabilized non-magnetism, by incorporating Cu, N and Al into a high manganese non-magnetic steel. CONSTITUTION:The high manganese non-magnetic steel used at super-low temperatures contains 0.3-1% of C, 12-25% of Mn, 0.5-10% of Ni, 0.5-4% of Cu, 0.001-0.3% of N and 0.001-1% of Al and, if necessary, 3% or more of Mo, 0.3% or more of Nb and 0.3% or more of V, and the balance of Fe and impurities. The Cu reduces the work hardening property, and stabilizes the austenite even at super-low temperatures to remarkably improve the ductility and toughness, and in this respect the amount of thereof should be 0.5% or more, while if the amount exceeds 4%, the hot working properties and resistance to cracking during welding will be worsened. To stabilize the austenite, the amount of N should be equal to the lower limit or more, while the excess amount thereof reduces the resistance to blow hole during welding. The Al serves to clean the impurities and to enhance the toughness, so that the amount thereof should be the lower limit or more, but it is not required to exceed the upper limit.
