Abstract

Abstract: The cold-work hardening performance and wear-corrosion resistance of ultra-low-carbon Cr-Ni-Mo austenite stainless steel 316L (/%： 0.023C, 0. 55Si, 0. 86Mn, 17. 57Cr, 11. 23Ni, 2. 03Mo) and antibacterial ultra-low-carbon Cr-Mn-Mo-N-Cu-Ag austenite stainless steel HNSAg (0. 024C, 0.48Si, 18.72Mn, 18.05Cr, 1. 96Mo, 0. 55N, 0. 48Cu, 0. 13Ag, 0. 12Nb) have been tested and studied. The steel HNSAg is melted by a 10 kg pressure induction furnace, forged to 15 mm plate and solid-solution-treated at 1 100 ℃ for 1 h, water-cooling. Results show that the deformation resistance of solid-solution-treated steel HNSAg is higher than that of steel 316L, but the steel HNSAg still maintains excellent plastic deformability, and at same wear-corrosion conditions the wear-corrosion resistance of steel HNSAg is better than that of steel 316L, its weight loss rate of wear-corrosion for 32 h is 1/2 that of steel 316L.

摘要： 试验研究了超低碳Cr-Ni-Mo奥氏体不锈钢316L(/%:0.023C,0.55Si,0.86Mn,17.57Cr,11.23Ni,2.03Mo)和抗菌超低碳Cr-Mn-Mo-N-Cu-Ag奥氏体不锈钢HNSAg(0.024C,0.48Si,18.72Mn,18.05Cr,1.96Mo,0.55N,0.48Cu,0.13Ag,0.12Nb)的冷作硬化和耐磨蚀性能。HNSAg钢由10 kg增压感应炉熔炼,锻成15 mm板,再经1 100℃1 h固溶水冷处理。结果表明,固溶状态的HNSAg钢的形变抗力较316L钢高,但仍然保持优良的塑性变形能力。在相同腐蚀磨损条件下,HNSAg钢耐磨蚀性能比316L钢高,其32 h耐磨蚀失重率约为316L钢的1/2。
