For the convenience of customers, as well as the safety of goods.

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 S690QL carbon steel plate sheet are higher than that of annealed S690QL carbon steel plate sheet, but the elimination of internal stress is not as good as annealing. The normalizing operation of S690QL carbon steel plate sheet is simple, the cost is low, the productivity is high, and it is widely used in actual production.

The Indian customer purchased our A516 Gr 70 pressure vessel steel plates to make tanks. They have very strict requirement for raw materials quality. For the A516 Gr 70 pressure vessel steel plates, they asked for Normalizing, 0℃ impact, A578 UT test, PWHT and so on tests, our Q/C department witness the production process with the technician from the customer company together. Meanwhile, we arrange BV inspection to check the quantity, spray mark, stamp on the A516 Gr 70 pressure vessel steel plates, and so on.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for S690QL carbon steel plate sheet, 42CrMo steel is quenching and tempering.

Our company has a strong, professional R & D team and advanced and perfect sales service concept, which makes our S690QL carbon steel plate sheet products have a high visibility and market share at home and abroad.
