The salesman of the company is familiar with all aspects of knowledge. Understand the company profile: group, company profile, various honor certification, enterprise's functional strength and other advantages analysis. Know the main product brand types and specifications of the company, and know the special knowledge of the product (production process and advantages of the product, simple identification method of product quality, etc.)

S420NL carbon steel material,Some low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but also in some cases take appropriate precautions and even be exposed to the atmosphere without coating. Elements that improve atmospheric corrosion resistance are copper, phosphorus, silicon, chromium, nickel, and molybdenum. The excellent atmospheric corrosion resistance has led to the formation of new concepts for structural design of buildings, bridges, and other structures.

NM series wear-resistant steel plates have uniform hardness, avoid the local fracture phenomenon caused by uneven hardness. Compared with ordinary steel plate, NM360 steel plate has wear resistance of not less than twice, NM400 steel plate has wear resistance of not less than 2.5 times, and NM550 steel plate has wear resistance of not less than 4 times. The wear-resistant steel plate combines the characteristics of high strength, high hardness, weldability and easy bending. S420NL carbon steel material

S420NL carbon steel material,Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.
