304 Stainless Steel Square Pipe

Stainless steel rectangular pipe is a kind of hollow strip of steel, a large number of pipe used for fluid transmission, such as oil, gas, water, gas, steam, etc., in addition, bending, torsional strength at the same time, light weight, so it is also widely used in the manufacture of mechanical parts and engineering structures.

Product Description

304 stainless steel tube is the most widely used stainless steel, food equipment, general chemical equipment, atomic energy industry equipment. 304 stainless steel pipe is a kind of universal stainless steel pipe, it is widely used in the production of requirements for good comprehensive performance (corrosion resistance and molding) equipment and parts. 304 stainless steel tube is the most widely used stainless steel, heat resistant steel. Used for food production equipment, Xitong chemical equipment, nuclear energy, etc. 304 stainless steel tube chemical composition specifications C Si Mn P S Cr Ni (nickel) Mo SUS304 ≤0.08 ≤1.00 ≤2.00 ≤0.05 ≤0.03 18.00-20.00 Stainless steel is a kind of universal stainless steel material, rust resistance than 200 series of stainless steel material is stronger.High temperature resistance is also good, up to 1000-1200 degrees. 304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance. 304 stainless steel material concentration ≤65% in the boiling temperature below the nitric acid, with strong corrosion resistance. It also has good corrosion resistance to alkali solution and most organic acids and inorganic acids.
