PROBLEM TO BE SOLVED: To provide a high Mn containing Fe-Ni-Cr alloy with excellent surface quality and a method for manufacturing the alloy at a low cost with a general purpose facility.SOLUTION: A high Mn containing Fe-Cr-Ni alloy includes 0.2% or less C, 0.1-1% Si, 4-20% Mn, 0.01% or less S, 25% or less Ni, 25% or less Cr, 0.001-0.1% or less Al, 0.0001-0.01% Mg, 0.0001-0.01% Ca, 0.0005-0.01% O and the balance Fe with inevitable impurities. The nonmetallic inclusion contained in the alloy includes one or two kinds from among MgO, MgO AlO, CaO-SiO-MgO-AlO-based oxide. The MgO AlOis 50% or less in a number ratio.SELECTED DRAWING: None |
