Genuine thin-wall stainless steel pipe in stock
304 large diameter stainless steel pipe is a kind of high alloy steel that can resist corrosion in air or chemical corrosion medium. 304 stainless steel pipe has beautiful surface and good corrosion resistance. It does not have to undergo surface treatment such as color plating, but gives full play to the inherent surface performance of stainless steel and is used in many aspects of steel.
9% nickel, 19% chromium, stainless steel, heat-resistant steel
Usually called stainless steel. Representative properties include 13 chromium steel, 18-8 chromium nickel steel and other high alloy steels. From the perspective of metallography, because stainless steel contains chromium, a very thin chromium film is formed on the surface, which is separated from the oxygen invaded in the steel and 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 universal stainless steel, which is widely used to make equipment and parts requiring good comprehensive performance (corrosion resistance and formability). 304 stainless steel is a brand of stainless steel produced according to American ASTM standards. 304 is equivalent to 0Cr19Ni9 (0Cr18Ni9) stainless steel in China. 304 contains 19% chromium and 9% nickel. 304 is the most widely used stainless steel and heat-resistant steel.
