Can you supply 300mm thick steel SA633 grade D carbon steel plate sheet

Vanadium mainly exists in the form of carbide in SA633 grade D carbon steel plate sheet and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.

The main uses of flat steel are as follows. First, flat steel is used as a raw material for processing steel plates, which is convenient for transportation, takes up a small space, and can save transportation costs. Second, SA633 grade D carbon steel plate sheet flat steel can be used as raw material for processing welded pipes. Flat steel can be a finished steel product, or it can be used as a billet for welded pipes and thin slabs for stacked sheets. Third, flat steel can be directly used as a steel structure. As a finished material, flat steel can be used for making hoop iron, tools and mechanical parts, and used as building frame structure and escalator in construction. Fourth, the flat steel has a smooth surface and a certain degree of beauty.

Q960 quenched and tempered steel plate classification: Q960C, Q960E, Q960D, Q960F. Welding performance of SA633 grade D carbon steel plate sheet, Q960D quenched and tempered high strength plate: carbon content and thermal sensitivity coefficient are greatly reduced in composition design to improve welding performance, so it has excellent welding joint performance, which can meet the welding requirements of bridges, buildings, cranes, shipbuilding, vehicles and large structural parts.

Our company's SA633 grade D carbon steel plate sheet power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the SA633 grade D carbon steel plate sheet utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
