304/304L STAINLESS STEEL TUBE
304 Stainless Steel Tube/Pipe:
Introduction:
304 stainless steel pipe standard: 304 stainless steel pipe is a brand of stainless steel produced according to American ASTM standard.
304 stainless steel pipe is equivalent to 0Cr19Ni9 (0Cr18Ni9) stainless steel pipe in China. 304 contains 19% chromium and 9% nickel. Standard for the trip to Germany: din2462.
Properties of 304 stainless steel: 304 stainless steel is the most widely used chromium nickel stainless steel, with good corrosion resistance, heat resistance, low temperature strength and mechanical properties. It is resistant to corrosion in the atmosphere. If it is industrial atmosphere or heavily polluted area, it needs to be cleaned in time to avoid corrosion. It is suitable for food processing, storage and transportation. It has good machinability and weldability.
use：
304 stainless steel pipe is a kind of universal stainless steel pipe, which is widely used to make equipment and parts with good comprehensive performance (corrosion resistance and formability). Such as food equipment, general chemical equipment, atomic energy industry equipment.

304 stainless steel is a kind of universal stainless steel material, and its antirust performance is better than that of 200 series stainless steel. High temperature resistance is also good, up to 1000-1200 degrees. 304 stainless steel has excellent corrosion resistance and intergranular corrosion resistance. A kind of
Features：
304 stainless steel has strong corrosion resistance in nitric acid below boiling temperature of 65%. It also has good corrosion resistance to alkali solution and most organic and inorganic acids. A kind of high alloy steel that can resist corrosion in air or chemical corrosion medium. Stainless steel has beautiful surface and good corrosion resistance. It doesn’t need to be treated by color plating and other surface treatment. It plays the inherent surface properties of stainless steel and is used in many kinds of steel. It is usually called stainless steel. The representative properties are 13 chromium steel, 18-8 chromium nickel steel and other high alloy steel. From the metallographic point of view, because the stainless steel contains chromium, a very thin chromium film is formed on the surface, which is separated from the oxygen invading into the steel and plays a role of corrosion resistance. In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 12% chromium.
