摘　　要：ND钢具有很高的抗硫酸露点腐蚀能力,并具有在含有SO_4^(2-)+Cl^-及Cl^-溶液中的高耐腐蚀性能。与20g相比,还具有较高的中温(200℃～400℃)力学性能,故在一定范围内可替代20g、Corten,Sten、CRI及普通304及316不锈钢。ND steel has been proved to have high resistance to sulfur dewpoint corrosion,SO42 +Cl- and Cl solutions,and also have high mechanical properties at temperatures up to 400℃.It is possible to replace mild steel 20g,low alloy steels,such as Corten,Sten,CRIA and stainless steels 304,316 etc. in certain conditions.
