Our company was founded in 2000, which initially committed to providing high-quality steel A514 Gr P alloy steel plate products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export A514 Gr P alloy steel plate steel to the international market, opening up the international steel market.
The alloy steel plates A514 Gr P alloy steel plate are among our main steel products. There are various alloy steel grades on the market. The most popular alloy steel materials are European material under EN10083-3 and Chinese material under GBT3077 for round bars and GBT11251 for plates. Our typical alloy steel grades are 51CrV4, 25CrMo4, 34CrMo4, 42CrMo4, 12Cr1MoV, 20Cr, 40Cr, 15CrMo, 30CrMo, 35CrMo, 42CrMo, etc.
Just as A514 Gr P alloy steel plate, the boiler steel plate also has strict control of chemical composition for the material, especially harmful elements such as phosphorus and sulfur, and residual elements such as chromium, nickel, and copper; during smelting, good deoxidation and removal of non-metallic inclusions should be carried out to ensure good quality, plasticity and toughness. The organizational structure requires uniformity, and the grain size is controlled within a certain range; there are also strict requirements for surface quality and internal defects. In addition, the boiler steel plate mechanical properties at room temperature and high temperature must be guaranteed.
When the A514 Gr P alloy steel plate, wear-resistant steel plate is produced, relevant heat treatment must be carried out, and then forging and processing are carried out after preheating. When the wear-resistant steel plate is heat treated, the temperature should be properly controlled. The heating temperature of the wear-resistant steel plate is 810-830 degrees, and the holding time depends on the furnace loading method. Tempering temperature: 320 degrees, sufficient time is necessary, oil cooling after tempering to reduce temper brittleness.
The carbon content of A514 Gr P alloy steel plate, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.
Our company has strict quality control standards. If you want to visit our factory, you are welcome at any time! We produce a lot of steel products every month to export A514 Gr P alloy steel plate to all over the world. Because our customers are from all countries, they will order a large number of steel products from our company every month.
Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, A514 Gr P alloy steel plate sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
