摘　　要：本文介绍了20GH新钢种的研制过程及采用此钢种试制中低压锅炉用电焊钢管的工艺,研制的钢管,其各项指标达到了GB3087—82标准的要求,可与无缝钢管媲美。The development of 20GH steel and the process of manufacturing welded pipes for middle & lower pressure boilers using the steel are described. All of the technical targets of the welded pipes meets the requirements of the standard GB3087-82 and the welded pipes can be compared with seamless tubes.
