The production technology of EN 10025-6 S690Q high strength steel

The wear-resistant layer of EN 10025-6 S690Q high strength steel wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy EN 10025-6 S690Q high strength steel carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This EN 10025-6 S690Q high strength steel production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate EN 10025-6 S690Q high strength steel size.
