304 stainless steel elbow in air or chemical corrosion medium can resist the corrosion of a chromium-nickel stainless steel, 304 stainless steel elbow Good corrosion resistance, does not have to go through a surface treatment such as color coating, can play the excellent corrosion resistance of stainless steel, 304 is a universal stainless steel, it is widely used in the production of seamless steel tubes and pipe fittings that require good comprehensive performance . Stainless steel grade "304" (S30400) is the name of the grade in American stainless steel standards, such as the ASTM standard. In China's newly formulated stainless steel grade standard GB/T20878-2007, the corresponding grade is 30408/06Cr19Ni10 (the previous grade is 0Cr18Ni9). This grade is typical of the famous Type 18-8 Cr-Ni austenitic stainless steel. Because it has excellent comprehensive properties and is widely used, its production and consumption account for about 80% of the total austenitic stainless steel.

Performance of 304 stainless steel elbow: 304 stainless steel elbow is the most widely used chromium-nickel stainless steel elbow in fluid pipe fittings, with good corrosion resistance, heat resistance, low temperature resistance and mechanical properties . Corrosion resistance in the atmosphere, whether it is an industrial atmosphere or a heavily polluted area, it should be cleaned in time to avoid corrosion. Suitable for food processing, petroleum, chemical storage and transportation. It has good processing performance and weldability. 304 stainless steel elbow has excellent resistance to stainless corrosion and good resistance to intergranular corrosion. It has strong corrosion resistance to oxidizing acids, such as nitric acid below the boiling temperature of Less than or equal to 65%. It also has good corrosion resistance to alkaline solution and most organic and inorganic acids. It has excellent hot and cold forming and processing performance. It can process and produce plates, tubes, wires, belts and various products, and is suitable for the manufacture of cold heads, deep drawing and deep drawing parts. Low temperature performance is better. At -180 degree C, the strength, elongation and shrinkage of the section are good. Since there is no brittle transition temperature, it is often used at low temperatures. It has good welding performance. It can be welded by the usual welding method, and no heat treatment is required before and after welding. Common angles of 304 stainless steel elbows: 45 degree, 60 degree, 90 degree, 180 degree
