316 stainless steel pipe is a kind of hollow elongated round steel pipe, which is mainly used in industrial transportation pipelines and seasonal structural components such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and so on. 316 stainless steel pipe has a maximum carbon content of 0.03 and can be used in applications where annealing after welding cannot be performed and where maximum wear and corrosion resistance is required. It has good welding properties and can be welded by all standard welding methods. Due to the addition of molybdenum Mo element, 316 stainless steel has greatly improved corrosion resistance and high temperature resistance, excellent work hardening (non-magnetic), and the appearance of cold-rolled products has good gloss. Compared with 304 stainless steel, the performance of the product has been improved. , the price is relatively high. Now, many home decoration and high-end commercial decoration will use 316 stainless steel, because of its strong corrosion resistance, the service life will increase compared to 304 stainless steel.
