zheheng steel is a one of supplier, exporter,manufacturer of stainless seamless steel tubing ,ERW stainless steel seamless tubing with compettive price high quality ,
The corrosion resistance of stainless steel seamless tubing depends on the alloying elements contained in the steel. Chromium is the basic element for obtaining corrosion resistance of stainless steel. When the chromium content in steel reaches about 12%, chromium reacts with oxygen in the corrosive medium to form a thin oxide film (self-passivation film) on the steel surface. It can prevent further corrosion of the steel matrix. In addition to chromium, the alloy elements commonly used in stainless steel seamless tubes are nickel, molybdenum, titanium, tantalum, copper, nitrogen, etc., to meet the requirements of stainless steel structure and performance for various purposes.
