316 stainless steel is resistant to erosion by marine and aggressive industrial atmospheres. Heat resistance 316 stainless steel still has good oxidation resistance in intermittent use below 1600 °C and continuous use below 1700 °C.
316 stainless steel pipe is a hollow strip of round steel, which is widely used in industrial transportation pipelines such as petroleum, chemical, medical, food, light industry, mechanical instrumentation and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures.
Manufacturing process：
Round tube billet → heating → perforation → head → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → blank tube → heat treatment → straightening → hydraulic test (inspection) → mark → in Library.
