摘　　要：JNS钢是采用Cu、Cr、Ti、Sb等的复合微合金化技术生产的耐硫酸露点腐蚀专用钢。在生产过程中合理设计化学成分,采用复合微合金化、LF炉精炼以及控制轧制等手段,使该钢耐硫酸露点腐蚀性高、焊接性能良好。通过工艺调整,解决了JNS含铜钢在中厚钢板生产中容易出现热脆的难题。自开发出JNS钢以来,在多个领域推广使用,已经生产14000多t,创造了较好的经济效益。JNS steel is a special steel of sulfuric acid dew corrosion- resistant. By advanced preeesses, such as Cu、Cr、Ti、Sb micro-alloying technology, LF refinement and control rolling etc, it has been researched and produced with higher resistance for sulfuric acid dew point corrosion and good welding properties. By improving preeess technology, hot brittle on the surface of JNS steel has been resolved. 14,000 tons has been produced since JNS steel been researched and developed. And it has made good economical returns and has been successfully applied in many fields.
