摘要：
A Ni free ferrous nonmagnetic alloy having excellent corrosion resistance and workability and high cost performance is described.The alloy comprises, by weight, 9 to 25% Cr, 3 to 35% Mn, 3 to 40% Co and the balance Fe and incidental impurities, and sum of Mn and 0.6Co is in accordance with a general relationship as indicated by formula 1/ , and preferably a restricted relationship as indicated by formula 2/ .19%.ltoreq.Mn+0.6 Co.ltoreq.40% 1/22%.ltoreq.Mn+0.6 Co.ltoreq.36% 2/One type of alloy of this invention further containing 0.02 to 2% Ag has excellent machinability as well as corrosion resistance, workability and nonmagnetism.
