Q345 is a steel material. It is a low alloy steel, with good comprehensive properties, low temperature properties, cold stamping properties, S355M VS S355ML welding properties and machinability. Q345 steel is subdivided into Q345A, Q345B, Q345C, Q345D and Q345E. This is the grade distinction, which represents that the impact temperature is different! Q345A, no impact; Q345B, impact at 20 degrees normal temperature; Q345C, impact at 0 degrees; Q345D, impact at - 20 degrees; Q345E, impact at - 40 degrees. At different impact temperature, the impact value is different.
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, S355M VS S355ML, hot rolled steel strip and steel plate are widely used and have more and more competitive strength in the market.
Hot-rolled coil is a commonly used steel product in the industry. It has a relatively wide variety of products and a wide range of uses. S355M VS S355ML, Hot-rolled coils are widely used in related industries such as petrochemical equipment, automobiles and bridges. Hot-rolled coils are also used in machinery industries such as ships and automobiles because of their good toughness and relatively high strength.
Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s S355M VS S355ML domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.
