Export SPA-H steel section 1220-4200mm width range

According to different purposes, the thin steel sheets are rolled from billets of different materials. Commonly used materials include plain carbon steel, such as SPA-H steel section, high-quality carbon steel, alloy structural steel, carbon tool steel, stainless steel, spring steel, and silicon steel for electrical purposes. The thin steel sheets are mainly used in the automobile industry, aviation industry, enamel industry, electrical industry, machinery industry and other sectors. In addition to delivery directly after rolling, there are also pickled, galvanized and tinned thin steel sheets.Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of SPA-H steel section circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and SPA-H steel section management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.Three advantages of semi-endless rolling technology: 1. The limit specification of Q345B steel is expanded from 1.5 mm × 1300 mm to 1.5 mm × 1600 mm. 2. the semi-endless rolling technology can effectively reduce the fluctuations in the temperature, size, and shape control accuracy of the strip head and tail. 3. The different parts of the strip steel SPA-H steel section produced by semi-endless rolling have uniform structure and mechanical properties, the yield strength fluctuation is less than 40 MPa, and the tensile strength fluctuation is less than 20 MPa.Different from SPA-H steel section, the alloy wear-resistant layer of alloy plate is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium, nickel are also added. The carbides in the metallurgical structure are distributed in a fibrous shape, and the fiber direction is perpendicular to the surface. Carbide microhardness can reach HV1700-2000 and surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good anti-oxidation properties. They are fully used within 500°C.First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
