NM400 steel is a high-strength wear-resistant steel plate. A514 Gr T alloy steel plate, NM400 steel has quite high mechanical strength; its mechanical properties are 3 to 5 times that of ordinary low alloy steel plates; NM400 steel plate can significantly improve the wear resistance of mechanical related parts; therefore, it can increase the service life of machinery and reduce production costs. NM400 wear-resistant steel plate is mainly used for processing and manufacturing of wear-resistant and wearing parts for mining and various construction machinery.
The company attaches great importance to systematic management, and has passed the A514 Gr T alloy steel plate ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on A514 Gr T alloy steel plate 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%.
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 A514 Gr T alloy steel plate 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 A514 Gr T alloy steel plate steel plate products are now exported to the South Asia, the Middle East, Europe and the United States.
At the initial stage of corrosion, the rust layer on the surface of weathering steel is denser than that of carbon steel, A514 Gr T alloy steel plate, 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.
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.
