Mild Steel Plate A387 GR.22 CL.1 pressure vessel steel sheet Composition

Low carbon steel is a carbon steel with a carbon content of less than 0.25%. Low carbon steel A387 GR.22 CL.1 pressure vessel steel sheet is also called soft steel or mild steel because of its low strength and low hardness. Low carbon steel includes most common carbon structural steel and a part of high-quality carbon structural steel, most of which are used for engineering structural parts without heat treatment, and some A387 GR.22 CL.1 pressure vessel steel sheet are carburized and other heat treated for mechanical parts that require wear resistance.

Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. A387 GR.22 CL.1 pressure vessel steel sheet, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.

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 A387 GR.22 CL.1 pressure vessel steel sheet are higher than that of annealed A387 GR.22 CL.1 pressure vessel steel sheet, but the elimination of internal stress is not as good as annealing. The normalizing operation of A387 GR.22 CL.1 pressure vessel steel sheet is simple, the cost is low, the productivity is high, and it is widely used in actual production.

Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s A387 GR.22 CL.1 pressure vessel steel sheet domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.

The company has a professional after-sales service team and good after-sales service reputation, providing full and uninterrupted after-sales service, to ensure timely and rapid solution to customer problems. The company is recognized as a 5-star brand of market quality cost performance and customer satisfaction by Market Research Center, and rated as "AAA credit enterprise of enterprise credit evaluation", and also a leading steel producer and service provider in the world.
