Carbon Steel Weldability - Seamless Steel Pipe,ERW steel

Medium welded carbon steel pipe. Carbon mass fraction of 0.25% ~ 0.60% for medium carbon steel. When the mass fraction of carbon and manganese content of nearly 0.25% is not high, good weldability. With the increase of carbon content, weldability gradually deteriorated. If the carbon content is about 0.45%, while based upon the welding mild China S275 S355 LSAW/SSAW Mild Black Coated Steel Pipe China S275 S355 LSAW/SSAW Mild Black Coated Steel Pipe for Pipeline Building Construction, Find details about China Building Material, Carbon Steel Pipe from S275 S355 LSAW/SSAW Mild Black Coated Steel Pipe for Pipeline Building Construction - EZ Steel Industrial Co., Ltd.
