hot sale price 304 seamless stainless steel pipe

304 seamless stainless steel pipe has no trachoma, no sand hole, no black spots, no cracks which always beading smooth. It had excellent performance of bending, cutting, welding processing and has stable nickel content.

304 seamless stainless steel pipe can be resistant to air, steam, water or other weak corrosive media and acid, alkali, salt environment. It is widely known as stainless acid resistant steel pipe. The corrosion resistance of the 304 seamless pipe depends on the content of alloying elements in the steel. Chromium is the basic element to obtain corrosion resistance of stainless steel. When the content of chromium reach about 12%, In the role of oxygen for chromium and corrosive media it shall form a thin layer of oxide film (self-passivation film) in the steel surface which can prevent further corrosion of the steel matrix. In addition to chromium, stainless steel seamless pipe commonly have many alloy elements such as nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the various requirement of stainless steel organization and performance requirements.

304 seamless stainless steel pipe is a hollow long circular steel, which can be widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other fields. In addition, when the bending and torsion strength is same, it had lighter weight, which also be widely used in the manufacture of mechanical parts and engineering structure. And also used for the production of conventional weapons, barrels, shells etc.
