Functions of stainless steel industrial pipes

Functions of stainless steel industrial pipes

The corrosion resistance of stainless steel industrial pipes depends on the alloying elements contained in the steel. Chromium is the fundamental element that makes stainless steel pipes corrosion resistant. When the chromium content in the steel reaches about 12, the chromium and the oxygen in the corrosive medium form a very thin oxide film (self-passivation film) on the surface of the steel. , Can prevent further corrosion of the steel matrix. In addition to chromium, the commonly used alloying elements of stainless steel industrial pipes include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses for the arrangement and function of stainless steel pipes.
