摘要/Abstract

摘要： 试验用304J1奥氏体不锈钢(/%:≤0.08C、≤1.70Si、≤3.00Mn、15～18Cr、6～9Ni、1～3Cu)经10kg真空感应炉熔炼,锻成Φ40 mm钢棒,并经1080℃10 min,固溶处理、水冷。试验研究了0.05%～2.52%Cu对试验钢(/%:0.054～0.068C、0.45～0.63Si、1.82～1.95Mn、17.26～17.62Cr、6.42～6.49Ni)力学性能的影响,并对比分析了试验钢304J1和304DDQ深冲钢(/%:0.04C、0.32Si、1.17Mn、18.11Cr、8.66Ni)的30%冷变形产生50%马氏体的温度-冷加工诱变马氏体转变点M_d30,堆垛层错能和深冲杯凸(CUP)值:得出将304J1钢铜含量目标成分设定为1.50%时,室温力学性能、冷加工塑性、深冲性能及经济性的匹配性最佳。工业生产表明,1.50%Cu 304J1钢0.27 mm板的深冲值≥13 mm与304DDQ钢相当。

Abstract: The tested austenitic stainless steel 304JI (/%:≤0. 08C, ≤1.70Si, ≤3.OOMn, 15 〜18Cr, 6 〜9Ni, 1 〜3Cu) is melted by a 10 kg vacuum induction furnace, forged to Φ40 mm bar and solid-solution heat-treated at 1 080 °C for 10 min, water cooling. The effect of 0. 05% 〜2. 52% Cu on mechanical properties of test steel (/%: 0. 054 ~ 0. 068C, 0. 45 〜0. 63Si, 1. 82 ~ 1. 95Mn, 17. 26 〜17. 62Cr, 6. 42 〜6. 49Ni) has been tested and studied, and the temperature formed 50% martensite in 30% cold deformation process* cold working induced martensite transformation point M_d30, the stacking fault energy (SFE) and the deep drawing cup value (CUP) of test 304J1 steel and deep drawing steel 304DDQ (/% ：0. 04C, 0. 32Si, 1.17Mn, 18.11Cr, 8. 66Ni) are compared and analyzed. It is obtained that as copper content in steel 304JI is 1. 50%, the matching of ambient mechanical properties, cold working plasticity, deep drawing performance and economy is best and the commercial production shows that the deep drawing value of 0. 27 mm sheet of 1. 50% Cu 304JI steel is '13 mm that is about equal to the deep drawing value of 304DDQ steel.
