Guarantee to thank the new and old customers for their trust with good products, excellent quality, low price and perfect service. The company provides customers with professional "one-stop" logistics services: warehousing, loading and unloading, and transporting. The perfect logistics management, facilities, network and guarantee system guarantee customers' worry-free delivery.
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 API 5L X70 (L485) PSL1 hot rolled carbon steel plate are higher than that of annealed API 5L X70 (L485) PSL1 hot rolled carbon steel plate, but the elimination of internal stress is not as good as annealing. The normalizing operation of API 5L X70 (L485) PSL1 hot rolled carbon steel plate is simple, the cost is low, the productivity is high, and it is widely used in actual production.
In year 2015, we ship 750 tons H beam to Pakistan for our old customer for building use. Because of urgent demand, the H beams are partial shipment by bulk vessel. Due to strong support of our customer, we also export many C channel steel, API 5L X70 (L485) PSL1 hot rolled carbon steel plate I beam and other profile steel to local market.
