摘　　要：研究了新型奥氏体不锈钢24Mn18Cr3Ni0.62N在室温下的拉伸性能。结果表明,该钢具有优良的室温拉伸性能,σ0.2=525MPa,σb=890MPa,δ=41%,ψ=57%,n=0.421。室温下断裂为韧性断裂,夹杂物为裂纹发源地之一,净化材料可以进一步提高材料的抗拉强度。Tensile properties of a new type austenitic stainless steel（24Mn 18Cr3Ni0.62N） at room temperature were studied,The results show that the austenitic stainless steel has excellent tensile properties ：σ0.2=525MPa,σb=890MPa, 6=41% ,δ=57 %, n=0.421.The fracture at room temperature is toughness fracture, The inclusions are one of the crack headstreams, and purifying the material can further enhance tensile strength of the material.
