Concentric reducer is the corrosion resistance of steel.
Concentric reducer corrosion resistance depends on the steel alloying elements. It contains chromium stainless steel stamping elbow is get the corrosion resistance of the basic elements, while about 1.2% chromium content in steel, chromium and oxygen effect of corrosive medium, in the steel surface to form a thin layer of oxide film (since the passivation film), but to prevent further corrosion of steel substrate. In addition to the chromium, the commonly used alloying elements and nickel, molybdenum, titanium, niobium, copper, nitrogen, etc, in order to meet the various USES of concentric reducer organization and performance requirements. Concentric reducer must be adopted in production of production and processing technology, guaranteed to show a good role in production and processing, and performance.
