High strength wear-resistant steel plates are used in mining equipment, cement machinery, metallurgical machinery, construction equipment, ship equipment, electrical equipment, port equipment, transportation and general machinery manufacturing industries. High strength wear-resistant steel plates are used by more and more enterprises because of their excellent wear resistance and the convenience of processing and using. The company has sufficient stocks of high strength wear-resistant steel plates, SM400A steel material with complete varieties and specifications.The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing SM400A steel material high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.S355J2 steel plate SM400A steel material rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the SM400A steel material single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃,SM400A steel material., Stainless steel relies on a very thin, solid, fine and stable chromium rich oxide film (protective film) formed on its surface to prevent oxygen atoms from continuing to infiltrate and oxidize, so as to obtain the ability of corrosion resistance. Once the film is damaged for some reason, the oxygen atoms in the air or liquid will continuously penetrate or the iron atoms in the metal will continuously separate, forming loose iron oxide, and the metal surface will be continuously rusted.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.
