Stainless steel pipe is a kind of hollow long round steel, which is mainly widely used in industrial transportation pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrumentation, etc.
In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in manufacturing mechanical parts and engineering structures. It is also commonly used as furniture, kitchen utensils, etc.

Stainless steel is a general-purpose steel with good corrosion resistance. Its thermal conductivity is better than that of austenite, the coefficient of thermal expansion is smaller than that of austenite, heat-resistant fatigue, adding stable element titanium, and good weld mechanical properties.
Stainless steel is used for building decoration, fuel burner parts, household appliances and household appliances; steel with free cutting performance is mainly used for automatic lathes, bolts and nuts. The addition of Ti or Nb to the steel reduces the content of C and improves the processing and welding performance. It is mainly used for hot water tanks, heating water systems, sanitary appliances, durable household appliances, bicycle flywheel, etc. |
