1.以下列各点作为特征的弹簧用奥氏体不锈钢: 其成分必须含有C 0.05～0.20%;Si 0.3～1.0%;Cr 13.0～16.0%;Mn 4.0～12.0%;Cu 0.5～4.0%;N 0.05～0.2%,余量是铁,而且通过对上述各成分的调整,使下式: H=1200-150×[Cu%]-45×[Mn%]-1010×[C%+N%]中的H值在100～300的范围内;通过冷轧可使其硬化。2.以下列各点作为特征的弹簧用奥氏体不锈钢: 其成分必须含有C 0.05～0.20%;Si 0.3～1.0%;Cr 13.0～16.0%;Mn 4.0～12.0%;Cu 0.5～4.0%;N 0.05～0.2%;余量是铁,通过对上述各成分的调整,使下式: H=1200-150×[Cu%]-45×[Mn%]-1010
1. Austenitic stainless steel for spring characterized by the following points: its composition must contain C 0.05-0.20%; Si 0.3-1.0%; Cr 13.0-16.0%; Mn 4.0-12.0%; Cu 0.5-4.0% N is 0.05 to 0.2%, and the balance is iron. By adjusting the above components, the following formula is satisfied: H = 1200-150 × [Cu%] - 45 × [Mn%] - 1010 × [C% + N% ] H value in the range of 100 to 300; it can be hardened by cold rolling. 2.
