Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, A572 grade 60 high strength steel based on a high starting point and high technology, the company has vigorously developed various steel products A572 grade 60 high strength steel and deep-processed parts, steel structures, precision castings, seamless pipes.
The seamless steel pipe for general use is rolled by common carbon structural steel, A572 grade 60 high strength steel, low alloy structural steel or alloy structural steel, with the largest output. It is mainly used as the pipe or structural part for conveying fluid. According to different uses, it can be divided into three categories: a according to chemical composition and mechanical properties; B according to mechanical properties; C according to hydrostatic test. If the steel pipe supplied according to class AB is used to accept liquid pressure, hydrostatic test shall also be carried out. The seamless pipes for special purposes include seamless pipes for boiler, chemical power, geological and petroleum, etc.
Our company produces ordinary carbon steel A572 grade 60 high strength steel with high strength and good plasticity and toughness. Due to the effect of alloy elements, its strength is 25% - 50% higher than that of ordinary carbon steel, its elongation is 15% - 23%, and its impact toughness at room temperature is higher than 60j / cm 2. We have a A572 grade 60 high strength steel production line specializing in the production of ordinary carbon steel plate, and strictly control its quality.
The martensite microscopic strength of the wear-resistant layer of the A572 grade 60 high strength steel, wear-resistant steel plate can exceed HVl700-2000, and the surface strength can exceed HRC58-62. The key to the wear-resistant layer of the wear-resistant steel plate is dominated by cobalt alloy, and other alloy components such as manganese, molybdenum, niobium, and nickel are added. The martensite in the alloy composition is filled with fibers, and the orientation of chemical fibers is vertical to the surface.
Plate 20 to 30mm thick A572 grade 60 high strength steel product: 20*1400*11400, 20*2100*7000, 20*2500*6200, 20*2933*7300, 20*3200*4400, 20.9*2851*7000, 21*2100*8810, 21.5*1630*13480, 22*3400*13000, 23.1*2590*7790, 25*1950*10150, 25*1950*9700, 25*2100*8400, 25*2100*8650, 25*2400*11600, 25*2400*8200, 28*2170*13000, 30*1600*10720, 30*1600*8600.
