The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep A709 grade 50W carbon steel plate processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and A709 grade 50W carbon steel plate steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.
Chromium element (Cr element) can improve the strength and hardness of A709 grade 50W carbon steel plate, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.
Q960D quenched and tempered high-strength steel is used to make pressure shell parts, deep tide lifesavers, high-pressure structural parts, aerospace equipment, armored vehicles, and manufacturing various engineering machinery, such as drilling rigs, electric shovel, and Electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and wear-resistant structural parts.
As of early November, China's pig iron output was 24.662 million tons. Although the output of pig iron has declined due to the suspension of production during the heating season, the rate of decline has been slow, still at a high level of over 24.5 million tons. This is 13.5% higher than the same period last year, which makes coke demand good, and the six rounds of increase have landed smoothly. Some areas such as Shandong even appear out of stock.
