EN steel grade S460NL material,17MN4 steel plate, , DIN 17135 17MN4 steel plate is a kind of material for boiler and pressure vessel steel. DIN 17135 17MN4 steel plate is characterized by a minimum yield strength of 220 - 295 MPa and by good weldability, so 17MN4 steel is mainly used for manufacturing boilers, pressure vessels and pipes transporting hot liquids.EN steel grade S460NL materialEN steel grade S460NL material,The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.EN steel grade S460NL materialQuenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.At the initial stage of corrosion, the rust layer on the surface of weathering steel is denser than that of carbon steel, and there are relatively few cracks and holes. After 25 days, delamination occurs in some parts of carbon steel and weathering steel, and there is no difference in corrosion products, mainly due to the role of alloy elements in the rust layer. The precipitation of Cu and Cr alloy elements in the weathering rust layer can resist the invasion of moisture and harmful ions in the atmosphere, and further corrosion of steel and base metal can be prevented, so as to achieve the effect of atmospheric corrosion resistance.EN steel grade S460NL material,Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
