The main varieties of hot-rolled steel plates are ordinary carbon steel, low alloy steel, container plate, weathering steel, pipeline steel, hot-rolled steel strip for automobiles, ship plate, gas cylinder steel, boiler and pressure vessel plate, A514 Gr Q QT steel plate. Hot-rolled steel strips are processed into different finishing lines to become steel plate, flat coil and slit steel strip products. Our hot-rolled steel plates are widely used in automobiles, machinery, ships, bridges, construction, pressure vessels, pipeline transportation, automotive industry.
The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our A514 Gr Q QT steel plate steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge A514 Gr Q QT steel plate steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.
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 A514 Gr Q QT steel plate increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of A514 Gr Q QT steel plate during tempering, while tempering determines the performance and life of the workpiece.
At the initial stage of corrosion, the rust layer on the surface of weathering steel is denser than that of carbon steel, A514 Gr Q QT 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.
If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
