Quenching technology of stainless steel elbow

　　After welding, stamping  stainless steel elbow sclerosing large, easily crack. If we use the same type of stamping stainless steel elbow welding must be preheated three hundred degrees above and after welding seven Baidu about slow cooling treatment if the welding conditions can not be heat treatment after welding should be used in stamping manufacturer of stainless steel elbow electrode. The stamping elbow can be machined with smaller size range. The inner wall of the pipe port is thin, and the wall thinning rate is too poor; it is necessary to reduce its plasticity.
