Knowledge:304 large diameter stainless steel Pipe in the air or
chemical corrosion medium can resist corrosion or a Kind of high
alloy
steel.304 stainless steel pipe is a beautiful surface and good
corrosion resistance,without plating color and other surface
treatment,and Play
the Inherent surface performance of stainless steel,used in a
variety Of steel.Usually called stainless steel.Represents the
performance of 13
Chromium Steel .18-8 chromium nickel steel and other high alloy steel.From the perspective of metallography analysis, because the
stainless
steel contains chromium and the surface of the formation of a very
thin chromium film, the film separated from the invasion of oxygen
in the
steel plays a role in corrosion resistance.In order to maintain the inherent corrosion resistance of stainless
steel, the steel must contain more
than 12% chromium.304 is a kind of universal stainless steel, which is widely used in
the production of equipment and parts requiring good
comprehensive properties (corrosion resistance and formability).304 stainless steel is a grade of stainless steel produced
according to
American ASTM standard.304 is equivalent to China's 0Cr19Ni9 (0Cr18Ni9) stainless steel.304 contains 19% chromium and 9% nickel.304 is
the most widely used stainless steel and heat resistant steel.
