EN steel grade S420N material can stand the test

Under normal exposure to the atmosphere, EN steel grade S420N material, bare steel forms a tight protective oxide film during the first few months of atmospheric corrosion. Sometimes architects choose bare steel structures because they want to get the appearance of uniform atmospheric oxidation on the steel surface, and sometimes they are to save the protective coating for economic purposes. To use these low-alloy high-strength steels in a bare state, the design must consider that the surface of the steel cannot be wet for a long time, and special attention should be paid to the special atmospheric environment to ensure that the corrosion rate of the steel is allowed under this condition.

The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our EN steel grade S420N material steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge EN steel grade S420N material steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.

The purpose of EN steel grade S420N material quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of EN steel grade S420N material. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.

The EN steel grade S420N material, wear resistant steel plate is composed of low carbon steel plate and alloy wear-resistant layer, and the alloy wear-resistant layer is 1/3 ~ 1/2 of the total thickness. The alloy wear-resistant layer and the base plate are metallurgically bonded. When working, the base plate provides comprehensive properties such as strength, toughness and plasticity to resist external forces, and the alloy wear-resistant layer provides wear-resistant properties to meet the requirements of specified working conditions.

Adhere to the spirit of quality first and user foremost, carry out maintenance and other work according to the requirements of the buyer's contract, and ensure that the engineering project and product after-sales play their application effectiveness. Our company guarantees to carry out self inspection and self supervision according to the quality management policy proposed by our company, and deliver a high-grade, perfect and excellent system engineering to users.
