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, A514 Gr R alloy steel plate based on a high starting point and high technology, the company has vigorously developed various steel products A514 Gr R alloy steel plate and deep-processed parts, steel structures, precision castings, seamless pipes.
ASME SA387Gr12CL2 steel plate chromium-molybdenum alloy steel plate has the properties of preventing hydrogen embrittlement, hydrogen corrosion, hydrogen peeling, and sulfide corrosion in a hydrogen environment at medium temperature (350-480 ℃), and has good low temper brittleness. A514 Gr R alloy steel plate, SA387 Gr12 CL2 steel plate is widely used in the manufacture of chemical fertilizer, petrochemical and thermal power plant equipment, such as synthetic ammonia reactor, coal gasifier, shift furnace and hydrogenation reactor.
Weather resistant steel, as a new generation of advanced steel materials, has atmospheric corrosion resistance 2 to 5 times that of ordinary carbon steel. The longer it is used, the more prominent the corrosion resistance. Because it has the characteristics of rust resistance, no coating, thinning and consumption reduction, labor saving and energy saving, weather resistant steel can be applied to steel structures used in buildings, vehicles, bridges, towers and other long-term exposure to the atmosphere, A514 Gr R alloy steel plate and can also be used to manufacture containers and railway Structural components such as vehicles, oil derricks, seaport buildings, and oil platforms.
S355J2 steel plate A514 Gr R alloy steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the A514 Gr R alloy steel plate single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.
A514 Gr R alloy steel plate 2020 China inventory: 8*2400*12000, 30*3020*7800, 20*1950*9000, 25*2210*9400, 8*2200*11200, 8*2400*12000, 22*3400*13000, 16*2150*10750, 27*3510*10500, 21.5*1630*13480, 13.6*2940*11455, 32*2520*7546, 16*2150*10450, 25*2500*12000, 8*2400*12000, 32*2500*6000, 16*2150*10350, 330*2200*4250, 22*3400*13000, 32*2500*6000, 12.9*2987*10384, 25*2700*9000, 14*1950*10000, 55*2200*8000, 13.6*2940*11455.
The company's after-sales service tenet is "customer first, timely guarantee, enthusiastic service and effective work". In order to establish a set of perfect after-sales service system and strict management system, so that the after-sales service can be effectively guaranteed. The company has set up after-sales service department to ensure timely, unique and effective response to every user's request, coordinate internal resources internally, and put an end to all evasion and delay.
