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, A588 Gr B heavy plate based on a high starting point and high technology, the company has vigorously developed various steel products A588 Gr B heavy plate and deep-processed parts, steel structures, precision castings, seamless pipes.
Abrasion resistant steel A588 Gr B heavy plate which is also known as (AR steel) wear resistant steel, is developed to have longer service life than mild steel. Abrasion resistant steel is widely used in underground mines, cement industry, road construction, mining and open-pit mining and metallurgical industries and manufacturing other wear-resistant parts.
There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products A588 Gr B heavy plate are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.
Try to use A588 Gr B heavy plate high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the A588 Gr B heavy plate temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. A588 Gr B heavy plate, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel A588 Gr B heavy plate plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
