304L Stainless steel pipe

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

304L contains less carbon than 304 and is more resistant to corrosion. After welding or stress relief, its resistance to grain boundary corrosion is excellent; in the case of no heat treatment, it can also maintain good corrosion resistance, and the operating temperature is -196 ° C ~ 800 ° C. It is used in field open-air machines in chemical, coal and petroleum industries that require high resistance to grain boundary corrosion, heat-resistant parts of building materials and parts with difficult heat treatment.
