不锈钢的高氮化不仅可提高钢的耐蚀性 ,而且可促进奥氏体相的稳定化和取代贵金属 Ni,从而达到产品品质与成本方面的双收益 ,然而 ,高氮不锈钢的生产必须在加压气氛下进行。目前 ,其制造方法主要有加压感应炉法、加压等离子炉法和加压电渣炉法 3种方式。现在欧洲已有 2 0 t/ 42 The high nitriding of stainless steel not only improves the corrosion resistance of the steel, but also promotes the stabilization of the austenite phase and replaces the noble metal Ni so as to achieve the double benefit of product quality and cost. However, the production of high nitrogen stainless steel must be added Pressure atmosphere. At present, the manufacturing methods include pressurized induction furnace method, pressurized plasma furnace method and pressurized electroslag furnace method 3 ways. There are now 20 t / 42 in Europe
