6mm thick EN steel grade S420NL material

Wear resistant steel plate is a kind of special plate product specially used under the condition of large area wear. At present, the commonly EN steel grade S420NL material used wear-resistant steel plate is a plate product made by overlaying a certain thickness of hard and wear-resistant alloy wear-resistant layer on the surface of ordinary low carbon steel or low alloy steel with good toughness and plasticity. The wear-resistant steel plate EN steel grade S420NL material consists of two parts: carbon steel plate and alloy wear-resistant layer.The company has allocated special environmental protection facilities for all pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, steel mill scale, environmental protection dust has reached 100%.Try to use high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.EN steel grade S420NL materialAlloy steel plate: The primary purpose of adding alloy elements to steel is to improve the hardenability of the steel, and it is easy to obtain martensite during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are smaller, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, EN steel grade S420NL material.If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.EN steel grade S420NL material
