304 stainless steel seamless pipe

Stainless steel seamless pipe is resistant to air, steam, water and other weak corrosive media and acid, alkali, salt and other chemical etching medium corrosion of steel pipes. Also known as stainless acid resistant steel pipe.

The corrosion resistance of stainless steel seamless pipes depends on the alloying elements contained in the steel. Chromium is the basic element to make stainless steel corrosion resistance, when the chromium content in the steel reaches about 12%, chromium and the oxygen in the corrosive medium, the formation of a thin oxide film on the surface of the steel (self-passivation film), can prevent further corrosion of the steel matrix. In addition to chromium, the alloy elements commonly used in stainless steel seamless pipes are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses for stainless steel structure and performance.

Stainless steel seamless pipe is a kind of hollow long circular steel, widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial transportation pipelines and mechanical structural components. In addition, the bending and torsional strength are the same, and the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used for the production of various conventional weapons, barrels, shells, etc.
