35SiMn steel can be used to manufacture parts with medium speed and medium load under the condition of quenching and tempering. 35SiMn steel can also be used to manufacture parts with high load, small impact and vibration, and parts with large cross-section and surface hardening, such as the main shaft and hub of steam turbine, impeller and various important fasteners, transmission shaft, main shaft, mandrel, connecting rod, gear, worm and trolley shaft in general machinery. In addition, A588 Gr B steel plate, 35SiMn steel can also be used to make thin-walled seamless steel pipe.The A588 Gr B steel plate plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The A588 Gr B steel plate products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched A588 Gr B steel plate increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of A588 Gr B steel plate during tempering, while tempering determines the performance and life of the workpiece.After adding trace elements such as phosphorus, copper, chromium, and nickel to Q355NH steel, a dense and highly adherent protective film is formed on the surface of the weathering steel, which prevents rust from spreading and developing, and protects the substrate under the rust layer to slow its corrosion . An amorphous spinel oxide layer of about 50 μm to 100 μm thick formed between the rust layer and the substrate is dense and has good adhesion to the base metal, which greatly improves the atmospheric corrosion resistance of the steel material, A588 Gr B steel plate.The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
