一种韧性较高的不锈钢及其生产方法
摘要：
本发明涉及一种韧性较高的不锈钢及其生产方法，该不锈钢在SUS316L的基础上进行改进，控制可以提高不锈钢强度的C、Si、Mn、Mo、Cr元素的含量，将其调整至标准要求含量的上限，增加少量可以提高不锈钢强度的Ti元素，其主要成分重量百分比为：C 0.02%~0.03%；Si 0.75%~1.0%；Mn 1.5%~2.0%；P≤0.020%；S≤0.010%；Ni 12.00~15.10%；Cr 17.00~19.00%；Mo 2.50~3.00%；N 0.15~0.22%；Ti 0.05~0.15%；Al 0.25~0.5%，通过热锻、温锻、固溶热处理相结合的锻造工艺，可以有效提高不锈钢的强度。
摘要（英）：

The invention relates to stainless steel with high toughness and a production method thereof. The stainless steel is obtained by making an improvement on the basis of SUS316L, controlling the contents of C, Si, Mn, Mo and Cr elements which can improve the strength of the stainless steel, adjusting the contents of the C, Si, Mn, Mo and Cr elements to the upper limit of the standard required contents, and adding a small amount of Ti elements which can improve the strength of the stainless steel. The stainless steel is mainly composed of, by weight, 0.02-0.03% of C, 0.75-1.0% of Si, 1.5-2.0% of Mn, less than or equal to 0.020% of P, less than or equal to 0.010% of S, 12.00-15.10% of Ni, 17.00-19.00% of Cr, 2.50-3.00% of Mo, 0.15-0.22% of N, 0.05-0.15% of Ti and 0.25-0.5% of Al. Through the forging process combining hot forging, warm forging with solid solution treatment, the strength of the stainless steel can be effectively improved.
