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 a573 grade 65 steel and a572 grade 65 steel differences are higher than that of annealed a573 grade 65 steel and a572 grade 65 steel differences, but the elimination of internal stress is not as good as annealing. The normalizing operation of a573 grade 65 steel and a572 grade 65 steel differences is simple, the cost is low, the productivity is high, and it is widely used in actual production.
Weathering steel plate refers to the low alloy structural steel with protective rust layer and atmospheric corrosion resistance, which can be used to manufacture steel structures such as vehicles, bridges, towers, containers, etc. Compared with a573 grade 65 steel and a572 grade 65 steel differences, ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared with stainless steel, weathering steel has only a small amount of alloy elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium and so on. The total amount of alloy elements only accounts for a few percent, instead of more than 10 percent as stainless steel, so the weathering steel price is relatively low.
The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, steel structure products, and intimate a573 grade 65 steel and a572 grade 65 steel differences after-sales service to customers. I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! The company sincerely hopes to establish a long-term cooperative relationship with them, mutual benefit and common development. Welcome to come and visit our a573 grade 65 steel and a572 grade 65 steel differences steel mill.
