摘要
不锈钢是工业与民用建筑中广泛应用的金属材料,按其组织状态分为马氏体不锈钢、铁素体不锈钢、奥氏体不锈钢、双相不锈钢四种类型。目前不锈钢冶炼技术已从一步法、二步法发展到三步法冶炼,生产工艺趋于成熟,钢种结构更加合理,市场应用更加广泛,需求已从民用转向工业应用,是国民经济中不可替代的产品。
Stainless steel is one metal material extensively applied in industrial and civil architecture.According to structure it can be divided into four kinds： martensite,ferrite,austenite and duplex stainless steel.At present its smelting technique has been developed from one-step,two-step to three-step method,production technology has been nearly ripe,grade composition more reasonable,market application even more wide spreading,and demand for it had been changed from civil to industry.It is a kind of product could not being replaced in national economy.
