S275JR carbon steel plate sheet chemical composition

The company covers an area of 15,000 square meters and the plant construction area is 10,000 square meters. We have introduced more than 50 sets of advanced S275JR carbon steel plate sheet production equipment, auxiliary equipment and testing equipment at home and abroad, more than 260 employees, more than 20 middle and senior management staff, more than 10 professional and technical personnel, annual production capacity of 100,000 tons. Main products: flat steel, S275JR carbon steel plate sheet steel pipe, steel plate, section steel, steel structure processing parts, etc. We also accept incoming materials and annealing processing.

The service temperature of high pressure seamless steel pipe is below 450 ℃, and the domestic pipes are mainly made of S275JR carbon steel plate sheet, No.10 and No.20 carbon steel hot-rolled pipes or cold drawn pipes. High pressure seamless steel pipe is often used in high temperature and high pressure conditions. Under the action of high temperature flue gas and water vapor, the pipe will be oxidized and corroded. The steel pipe is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good structure stability.

The weldability of S275JR carbon steel plate sheet is good. It means that under certain process and construction conditions, S275JR carbon steel plate sheet can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.

After twenty years of efforts, the company has completed the steel plates production process and complete testing equipment from smelting, rolling, drawing, heat treatment to S275JR carbon steel plate sheet full material. Large-scale production, intensive, and unremitting research and development and innovation make our products maintain long-term vitality. In early 2008, the company established the Ministry of foreign trade, and our S275JR carbon steel plate sheet steel plate products are now exported to the South Asia, the Middle East, Europe and the United States.
