The difference between hot-finished and cold-formed

Oct 02, 2018 · Such imports are invariably produced by a cold-formed process. This means that the tubes are simply cold formed to shape from strip and welded without any further processing to the tube or the weld region. Therefore, cold-formed tubes contain a Heat Affected Zone (HAZ), an area of micro-structural distortion around the weld region; this can be Structural hollow sections - SSAB - SSABSSAB manufactures cold formed and welded hollow steel sections, which according to EN 1993 (Eurocode 3) fall into buckling curve c (curve a or b in concrete filled columns). The buckling behavior of steel columns leads to situations where utilizing high strength steels is difficult especially with longer and slender columns. square steel profile, square steel profile Suppliers and Seamless mild steel 38mm black cast iron square hollow steel tube 1.Specification Tianjin Guangxin Iron And Steel Industrial & Trading Co..
