304 stainless steel is a versatile stainless steel material, anti-rust performance than the 200 series stainless steel stronger. Also relatively good high temperature, can be high temperature to the 1000-1200 degrees. 304 stainless steel pipe with excellent corrosion resistance between energy and good resistance to intergranular corrosion. On the oxidizing acid, obtained in the experiment: ≤65% nitric acid concentration below the boiling temperature of the 304 stainless steel tube with strong corrosion resistance. Most of the alkali solution and organic acids and inorganic acids also have good corrosion resistance of 201 stainless steel pipe weight formula: [(OD - Wall Thickness) * Thickness] * 0.02491 = kg / m (weight per meter). 201 stainless steel pipe with are: acid, alkali, high density without pinholes and other characteristics, is the production of the case, strap bottom quality materials. 201 stainless steel tube focus can be used for decoration pipe, industrial pipe, some of the light stretching of the products used. 201 stainless steel pipes used for the physical properties 1.
