The company's sales department has a professional team, they have professional steel knowledge, respond quickly, with the problems raised by customers can quickly give solutions, put the interests of customers first. With their own professional knowledge to provide customers with high-quality steel plate in line with the requirements. At the same time, in terms of price, we also have great advantages. Members of the business department make sure that the delivery time is short and the service is the best.
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 SA516 Grade 70 carbon steel equivalent are higher than that of annealed SA516 Grade 70 carbon steel equivalent, but the elimination of internal stress is not as good as annealing. The normalizing operation of SA516 Grade 70 carbon steel equivalent is simple, the cost is low, the productivity is high, and it is widely used in actual production.
