Product Introduction

304 stainless steel tube chemical composition specifications C Si Mn S Cr Ni (nickel) Mo SUS304 ≤0.08 ≤1.00 ≤2.00 ≤0.05 ≤0.03 18.00-20.00 8.25~ 10.50-304 Stainless steel is a kind of universal stainless steel material, Rust resistance is stronger than 200 series stainless steel material. High temperature resistance is also relatively good, can reach 1000-1200 degrees. 304 stainless steel has excellent corrosion resistance and good resistance to intergranular corrosion. 304 stainless steel material concentration ≤65% boiling temperature below the nitric acid, has a strong corrosion resistance. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids. In the air or chemical corrosive medium can resist corrosion of a kind of high alloy steel, stainless steel is a beautiful surface and good corrosion resistance, do not have to go through plating and other surface treatment, and play the inherent surface properties of stainless steel, used in many aspects of steel, usually called stainless steel. Representative properties are 13 chromium steel, 18-8 chromium nickel steel and other high alloy steel. From the metallographic point of view, because stainless steel contains chromium and the surface of the formation of a very thin chromium film, this film is separated from the oxygen intrusion in the steel has a role in corrosion resistance. In order to maintain the corrosion resistance inherent in stainless steel, the steel must contain more than 12% chromium.
