So that we can share experiences and lessons."
The company operates Henan metallurgical rolling iron and steel factory all year round, providing steel products for various industries such as ow alloy high strength series, boiler and pressure vessel steel plate, power station engineering steel plate series, A572 grade 55 ms steel coil bridge structure steel plate, corrosion resistant steel plate, composite steel plate, high-rise building structure, die steel plate series, steel plate series for shipbuilding and offshore platforms, pipeline steel plate, alloy structure and other steel plates.
40B steel plate is alloy structural steel plate formed by adding boron to the carbon structural steel with a carbon content of 0.40%. A572 grade 55 ms steel coil, 40B steel plate has high hardness, toughness and hardenability, and has good comprehensive mechanical properties after quenching and tempering, which can be used instead of 40Cr steel. 40B steel plate chemical elements: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.60-0.90, B: 0.0005-0.0035. 40B steel plate is used to manufacture parts with larger section and higher performance requirements.
Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized A572 grade 55 ms steel coil are higher than that of annealed A572 grade 55 ms steel coil, but the elimination of internal stress is not as good as annealing. The normalizing operation of A572 grade 55 ms steel coil is simple, the cost is low, the productivity is high, and it is widely used in actual production.
BBN steel strictly control quality of our carbon steel plate, alloy steel plates and structural steel plates. For A572 grade 55 ms steel coil ASTM A572 Grade 50 structural steel plate, Our Q/C Department will inspect dimension before shipment, making sure structural steel plate thickness tolerance and width, length tolerance are matchable to the A572 grade 55 ms steel coil standard requirements. The company is a good ASTM A572 grade 50 structural steel plate supplier in the globle market and the head is located in China. Welcome to send us inquiry and questions about structural steel plate.
