S420ML steel h beam cold rolled steel plate

SPV490 plate is a Japanese standard steel plate S420ML steel h beam for pressure vessels, which belongs to low alloy high-strength structural steel. It has high strength, good toughness, low welding crack sensitivity and corrosion resistance. SPV490 steel is mainly used to manufacture petroleum storage tanks. Vertical storage tanks are large containers assembled and welded on site. The welding quality of the welds directly determines the efficiency and life of the storage tank. Currently, high-efficiency automatic welding technology is generally used for welding.

The company attaches great importance to systematic management, and has passed the S420ML steel h beam ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on S420ML steel h beam quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.

Processing performance of quenched and tempered steel: S420ML steel h beam plate can be used for cold working, bending and cutting. When the gas is cut off, cracks will not occur even without preheating. When preheating processing, quenched and tempered steel needs to be processed below the tempering temperature. Superb wear and corrosion resistance: Because it contains alloy elements such as copper and chromium, it has good corrosion resistance, higher hardness, and good wear resistance compared with ordinary steel.

AR400 wear resistant steel is a special structural steel with high wear resistance. Generally speaking, the higher the hardness, the higher the wear resistance of the steel, S420ML steel h beam. The average hardness of AR400 wear-resistant special structural steel is 400HB. After quenching, AR400 wear resistant steel has good martensite bainite microstructure. The addition of Molybdenum (Mo), Nickel (Ni) and Boron (B) alloys ensures uniform texture in the whole thickness direction of AR400 wear resistant steel.

The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel. It can provide customers with drawing design, S420ML steel h beam deep processing services and installation solutions. 20 years of project experience has provided high-quality carbon steel, alloy steel products and high-quality after-sales service to customers in many countries around the world. The company has won widespread praise from customers.
