摘要：A material steel sheet for obtaining a high strength nonmagnetic austenitic stainless steel material having high elastic limit stress and excellent toughness is
provided.0.12% or less of C, 0.30 to 3.00% of Si, 2.0 to 9.0% of Mn, 7.0 to 15.0% of Ni, 11.0
To 20.0%, N: 0.30% or less, Mo: 3.0% or less, V: 1.0% or less, Nb: 1.0% or less, Ti: 1.0% or less, B: 0.010% or less, the balance being Fe and inevitable impurities and having a component composition such that the value of Ni equivalent is 19.0 or more, the austenite average grain size is d (m), dOf 0.40 or more, and the magnetic permeability after application of cold working with equivalent strain of 0.50 or more is 1.0100 or less.
