摘　　要：着重介绍了最新研制的耐硫酸露点腐蚀钢ND钢的力学性能、耐蚀性能,焊接工艺性能和耐蚀机理,并结合ND钢使用单位的实际情况,认为ND钢是理想的耐硫酸露点腐蚀材料,可广泛应用于电力、石化行业中锅炉管道、省煤器,空气预热器和烟囱等。Here described were the mechanics performance, corrosion-resisting performance.weldability and corrosion-resisting mechanisms of newly developed ND steel resistant to'dew point corrosion of sulfuric acid. The application shows that ND steel was the desired material resisting dew point corrosion of sulfuric acid' It could be widely used for boiler piping, coalescor, air preheater and stack, etc. in power generation and petrochemical industry.
