20GH鋼及用其制造中低壓鍋爐電焊鋼管的研究
A STUDY ON 20GH STEEL AND USING IT FOR MANUFACTURING WELDED PIPES FOR MIDDLE & LOWER PRESSURE BOILERS
-
摘要: 本文介紹了20GH新鋼種的研制過程及采用此鋼種試制中低壓鍋爐用電焊鋼管的工藝,研制的鋼管,其各項(xiàng)指標(biāo)達(dá)到了GB3087—82標(biāo)準(zhǔn)的要求,可與無縫鋼管媲美。Abstract: 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.
