【摘要】 不锈钢焊管生产在我国已经发展了25年,但是进入耐腐蚀管道主流工业应用市场才只有10年多。介绍了国外及我国不锈钢焊管生产发展的一些新状况,指出扩大品种规格将成为目前我国不锈钢焊管生产发展的新动力。特别应该重视奥氏体/铁素体双相不锈钢、含N奥氏体不锈钢、高Mn高N奥氏体不锈钢、第二代及超级铁素体不锈钢等高性价比的不锈钢焊管新品种的研发。更多还原

【Abstract】 There have be 25 years in China to product welded stainless steel pipe/tube,but only ten years entrance to major industry application area of anti-corrossion pipe/tube.In this paper some of the new state about production development of welded stainless steel have been reviewed in the world and in China,and new power of production development of welded stainless steel pipe/tube in China has be to extend grade of stainless steels and size.High performance/price ratio and welded stainless steel pipe/tube,such as duplex stainless steel,austenitic containing N stainless steel,austenitic containing high Mn and N stainless steel,secondary and super ferritic stainless steel welded pipe/tube should be developed in China.更多还原
