The hot rolling method is to heat the A283 grade D CS steel carbon plate steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of A283 grade D CS steel carbon plate rolling process is usually called semi-finished product production, also called blank production.
South Korean A283 grade D CS steel carbon plate steel industry said that the slowdown in economic growth superimposed on the impact of the epidemic, steel demand weakened, exports were sluggish, enterprises are facing huge operating pressure. Due to the delay in the resumption of work of Chinese A283 grade D CS steel carbon plate steel enterprises, the steel inventory is growing rapidly. According to statistics, China's steel circulation inventory reached 23.75 million tons in February, the highest since 2006, with an estimated total inventory of 33.45 million tons.
Q690D steel material is a low-alloy ultra-high strength steel grade. Standard: GB/T 3077. The hardenability of steel is high, and the critical hardenable diameter in oil is 60mm (96% martensite). After quenching and tempering, steel can obtain high strength, and has certain toughness, and can be processed into shape. But cold deformation plasticity and weldability are low.
The company is a leading steel production and exporting group in steel materials with advanced production technology, metal-cutting skill, and steel structures engineering projects. We can supply carbon steel plate and sheet, alloy steel plates and structural A283 grade D CS steel carbon plate steel plates. These hot rolled steel plates are sturdy plates having high quality. Their imperviousness to effect and scrapped area, weld capacity, and workability make them a worthy product in a variety of industries.
