s355j2w chemical composition yield reached the leading level in China

Based on the s355j2w chemical composition steel trade, the company mainly deals in Baosteel products: color coating, zinc plating, fingerprint resistance, cold rolling, hot rolling, pickling, electrical steel and other products, and can order the futures of the company's products on behalf of manufacturers. It has established cooperative relations with more than 2000 foreign customers. At the same time, it also operates a variety of products of related iron and steel enterprises. Annual sales of s355j2w chemical composition steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel.

SA517GrQ material is a high-strength quenched and tempered alloy steel plate, which belongs to the steel for offshore oil drilling racks. The upper limit of SA517GrQ steel plate thickness is 150mm, and the upper limit of rack steel is 177.8mm. BBN STEEL has opened up a new heat treatment process route for the 177.8mm thick offshore platform rack steel A517GrQ, and strives to improve the production capacity of this product.

Cold rolled coil products s355j2w chemical composition have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products s355j2w chemical composition is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils s355j2w chemical composition with different surface roughness can be produced (glossy surface or matte surface, etc.).

The addition of Ca element in steel such as s355j2w chemical composition can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.

As per JIS G3101 standard, the Carbon (C), Silicon (Si) and Manganese (Mn) content of SS400 steel plate are not controlled. Phosphorus (P) content of s355j2w chemical composition, JIS SS400 steel plate is 0.050% Max and Sulphur (S) content is 0.050% Max. The SS400 steel melting point is 1430 Degree Celsius, Brinell Hardness is 160HB, density is 7.85g/cm3, Young’s Modulus is 190-210Gpa. The strength and elongation of JIS SS400 steel plate varies with thickness. Generally, the tensile strength of SS400 steel plate is 400-510 Mpa. Elongation is above 21%. Yield strength ≥245Mpa for thickness≤16mm. When the JIS SS400 steel plate is thciker than 100mm, the yield strength shall not less than 205Mpa.
