09CuPCrNi-A steel TBT material prices opened a narrow range of shock market

The steel plates for SA302GrC boilers must withstand different pressures and strengths due to the manufactured containers. Generally, the normal pressure is 314MPa or higher, and the working temperature is often between -20°C and 450°C. According to the working conditions and processing requirements of the vessel, the steel plate must have good cold bending and welding performance, good plasticity and toughness, and high temperature short-term strength or long-term strength performance.

09CuPCrNi-A steel TBT material, Wear-resistant steel plates are mainly made of some alloying elements, such as manganese, silicon, chromium, vanadium, aluminum, titanium, boron, rare earths elements and so on. Generally, manganese and silicon are added first, because this can further strengthen the deoxidation effect, and because their prices are relatively low, adding them early can ensure the yield of the elements added later.

Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while 09CuPCrNi-A steel TBT material steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of 09CuPCrNi-A steel TBT material steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
