Stainless steel welded pipe, referred to as welded pipe, is a steel pipe made by welding commonly used steel or steel strip after crimping through a unit and a mold.

Stainless steel welded pipes are mainly used in heat exchanger pipes, fluid pipes, pressure pipes, pipes for mechanical structures, urban landscapes, and other industries.

Low temperature embrittlement---In a low temperature environment, the deformation energy of 316L stainless steel welded pipe is small. In a low temperature environment, the reduction in elongation and area reduction is called low temperature embrittlement. Most ferritic stainless steels exhibit this low-temperature emission.
