304 Seamless AISI Standard 0.8mm Ss Square Pipe
Seamless steel tube, made of whole metal, without seams, so called seamless steel tube.According to the production method, seamless tube divided hot rolled tube, cold rolled tube, cold drawing tube, extruded tube, top tube, etc .Our product is cold rolled or cold drawing then honed or SRB(skived rolled burnished) ,the surface polished some lathed. |
