The rolling state and temperature of EN steel grade S420N material

Cold rolled steel sheet has high strength, high hardness and high surface finish. It is generally thin steel plate and can be used as stamping steel plate. The strength of EN steel grade S420N material, hot rolled steel plate is relatively low, the surface quality can not match with that of cold rolled steel sheet. But its plasticity is good, and it is generally medium thick steel plate. The price difference between cold rolled steel sheet and hot rolled steel plate has a certain relationship with manufacturers. The quality of steel plate manufactured by different manufacturers is different, and the price is also biased.

Corrosion resistant steel is a kind of steel which can resist corrosion in air or weak medium and other strong corrosive medium. Corrosion resistant steel is also a kind of stainless steel. The corrosion resistance of corrosion resistant steel is better than that of stainless steel. EN steel grade S420N material, Corrosion resistant steel has good machinability and high corrosion resistance in normal indoor environment. In the project, it can be used for its good corrosion resistance, and can be cut into steel with desired shape at will.

Most common EN steel grade S420N material steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled EN steel grade S420N material steel plates.

Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s EN steel grade S420N material 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.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
