摘　　要：对用中频感应炉熔炼,电渣二次重溶工艺制备的Fe-Cr-Mn-C-N无镍奥氏体不锈钢进行了组织与性能测试。结果表明,该钢为单相奥氏体,平均晶粒直径为85μm,钢中成分均匀,未发现元素偏析;该钢具有较好的强度和韧性σb=1205MPa,σ0.2=632MPa,δ5=39%,HV=296。Fe-Cr-Mn-C-N non-nickel austenite stainless was prepared by medium-frequency induction furnace smelting and electro slag quadratic techniques.The structure and performance of the steel was measured,indicating that its phase structure is single-phase austenite and the average grain size crystal diameter is 85μm,no element segregation was founded in the steel.The mechanical properties of the steel are as follows:σ_b=1205(MPa),σ_ 0.2 =632MPa,δ_5(%)=39,HB=296,which displays better hardness and toughness.
