316L Stainless Steel Seamless Tube
316L Stainless Steel Seamless Tube
The difference between 316l stainless steel pipe and 316l stainless steel seamless pipe is: the American standard 316L stainless steel seamless pipe is definitely TP316L seamless pipe. The 316L stainless steel pipe, including 316L seamless pipe (SML) and welded pipe (WLD), deep cold processing pipe (HCW)3 kinds. If it is welded pipe, add WLD or W to the grade of the material, such as A312-TP316L-WLD. For seamless pipes, SML or S is added, and for deep cold working pipes, HCW is added.
