ASTM A213 TP 304L stainless pipe

TP304L Stainless Steel Pipe is widely used in petroleum, chemical, medical, food, light industry, machinery, instrument and other industrial pipeline and mechanical structure parts, etc. In addition, in bending and torsion strength, the weight is lighter, so it is also widely used to make mechanical parts and engineering structures.
