S355J2W high-speed project steel chemical composition

The company's sales department has a professional team, they have professional steel knowledge, respond quickly, with the problems raised by customers can quickly give solutions, put the interests of customers first. With their own professional knowledge to provide customers with high-quality steel plate in line with the requirements. At the same time, in terms of price, we also have great advantages. Members of the business department make sure that the delivery time is short and the service is the best.

S355J2W high-speed project steel, Wear resistant steel plate is more and more widely used. Some manufacturers make mass production, but the market is still in short supply, the prospect of wear resistant steel plate is very broad. In the production process of S355J2W high-speed project steel, wear-resistant steel plate, we must control the carbon content. For NM360 wear-resistant steel plate, its C content is 0.12%, which is longitudinal fracture. The probability of longitudinal fracture of steel with high content of S, P and Se is much higher than that of steel with manganese content of 0.7%.

"A283C is same as A283 Gr C, A283 grade C. A283C plate technical parameters: A283C plate chemical composition - max. 0.24% carbon, max. 0.40% silicon, max. 0.90% manganese, max. 0.035% phosphorus, max. 0.040% sulphuric, and min. 0.20% Cu. A283C plate mechanical properties: min. yield strength is 205 MPa, tensile strength is 380-515MPa, min. elongation is 22% in 8"" and 25% in 2"". Tolerance of A283C plate is subject to ASTM A6. The density of S355J2W high-speed project steel, A283C plate is 7.85g/cm3."

The wear-resistant layer of S355J2W high-speed project steel wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy S355J2W high-speed project steel carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.

Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries. The products S355J2W high-speed project steel are sold in more than 20 provinces, cities and all over the world. The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products.
