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, 1.7213 hot rolled heat treatable steel plate based on a high starting point and high technology, the company has vigorously developed various steel products 1.7213 hot rolled heat treatable steel plate and deep-processed parts, steel structures, precision castings, seamless pipes.

Q355GNH weather-resistant steel, that is, atmospheric corrosion-resistant steel, is a low alloy steel series between ordinary steel and stainless steel. 1.7213 hot rolled heat treatable steel plate, Q355GNH alloy steel plate and sheet are mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time. It is used to manufacture containers, railway vehicles, oil derricks, seaport buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.

Because 1.7213 hot rolled heat treatable steel plate, boiler steel plate is a product of important use, the safety and reliability requirements are strict, and the manufacturing technology is difficult. The boiler steel plate material must have the following main characteristics:The boiler steel plate has high yield strength performance in a certain temperature range (medium temperature and high temperature);The boiler steel plate has sufficient toughness, no brittle failure accident will occur during manufacturing or use.

1.7213 hot rolled heat treatable steel plate, ASTM A302 Grade B/A302 Gr.B vessel plates boiler steel sheets are manganese-molybdeum-nickel alloy steel plates, which are widely used in petroleum, chemical industry, power station, boiler, etc, to make the reactor, heat exchanger, separator, spherical tank, liquefied gas, nuclear reactor pressure vessel, boiler steam drum steam, liquefied petroleum, hydropower station and so on.

NM450 steel plate thickness≦80mm. 1.7213 hot rolled heat treatable steel plate, NM450 wear-resistant steel plates are used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery, abrasive tools, bearings and other product parts.NM450 Cchemical composition: C≤0.35; Si≤0.70; Mn≤1.70; P≤0.025; S≤0.010; Cr≤1.10; Ni≤0.80; Ti≤0.050; Mo≤0.55; B: 0.0005-0.006; Al≥0.010. Mechanical properties: Tensile strength Rm / MPa ≧ 25; -20 ℃ impact energy absorption (longitudinal) KV2 / J ≧ 24Surface Brinell hardness HBW: 420-480

The company specializes in hot rolled plates producing, steel plate processing, steel plates cutting, carbon steel plate weldding and exporting of wide and thick steel plates. BBN company has high-quality CNC 1.7213 hot rolled heat treatable steel plate steel plate cutting processing equipment, professional technical personnel, and supporting marketing and after-sales service system.
