The difference between Steel S275J2 hot rolled Plate, hot rolled sheet and cold rolled sheet: hot rolled sheet has low hardness, easy processing and good ductility. The cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The cold rolled sheet is mostly used in automobile manufacturing and electrical products. Therefore, the two have their own characteristics. According to these characteristics, it is more appropriate to choose the right rolled plate to maximize its effect and benefit.

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 Steel S275J2 hot rolled Plate are higher than that of annealed Steel S275J2 hot rolled Plate, but the elimination of internal stress is not as good as annealing. The normalizing operation of Steel S275J2 hot rolled Plate is simple, the cost is low, the productivity is high, and it is widely used in actual production.

Our client purchase more than 900 tons pipe Steel S275J2 hot rolled Plate from India. And we do the inspection for each one pipe before shipment.During the inspection, the inspector saw that the surface of the square pipe kept the original color of the stainless steel, no fracture, no depression and other quality defects was found.
