The main function of boron in A514 Gr M alloy steel plate and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.
The company attaches great importance to systematic management, and has passed the A514 Gr M alloy steel plate ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on A514 Gr M alloy steel plate quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.
The SM570 steel plate has a yield strength of more than 460MPa and a 60Kg strength grade steel because it contains a variety of alloying elements, including microalloying elements, and can often achieve higher strength in the state of hot rolling or controlled rolling, but the impact toughness fluctuates greatly. A514 Gr M alloy steel plate product Normalizing has the advantages of uniform and stable steel structure and performance, high qualification rate, and easy control of the production process.
Hot rolling and cold rolling are all the processes of forming steel plates or profiles, which have a great influence on the structure and properties of steel. The rolling of steel is mainly hot rolling, and cold rolling is usually used to produce small size steel and thin plate. With the development of new technologies such as the precision of hot rolling size, shape and surface quality and the continuous emergence of new products, A514 Gr M alloy steel plate, hot rolled steel strip and steel plate are widely used and have more and more competitive strength in the market.
