SUS304L Polishing Stainless Steel Tube is made of the material of 304L. 304L is a variation of 304 stainless steel used in the occasion which needs welding. 304L stainless steel welded pipehas low carbon content so it has good flexibility and corrosion resistance because carbide precipitation may lead to corrosion of welding. We are experienced in manufacturing 304L stainless steel thin-wall welded pipe
Stainless steel thick-walled pipe, Small stainless steel welded pipe, Large stainless steel welded pipe
