Food Grade 304 304L 316 316L 310S 321 Seamless Stainless Steel Tube SS Pipe
Stainless steel seamless pipe is resistant to weak corrosive medium such as air, steam and water and chemical corrosive medium such as acid, alkali and salt. Also known as stainless acid resistant steel pipe.
The corrosion resistance of stainless steel seamless pipe depends on the alloy elements contained in the steel. Chromium is the basic element to obtain corrosion resistance of stainless steel. When the chromium content in the steel reaches about 12%, a thin oxide film (self passivation film) is formed on the surface of the steel due to the interaction between chromium and oxygen in the corrosive medium, which can prevent further corrosion of the steel substrate. In addition to chromium, nickel, molybdenum, titanium, niobium, copper, nitrogen and other alloying elements are commonly used in stainless steel seamless pipe to meet the requirements of various uses for stainless steel structure and properties.

Stainless steel seamless pipe is a kind of hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in manufacturing mechanical parts and engineering structures. It is also used to produce all kinds of conventional weapons, barrels, shells, etc.
