Carbon Steel Standard EN 10025-6 high strength steel 1.8904

In recent years, in line with the development trend of iron and EN 10025-6 high strength steel 1.8904 steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which EN 10025-6 high strength steel 1.8904 are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

Generally, the production process of EN 10025-6 high strength steel 1.8904 seamless steel tube can be divided into cold rolling and hot rolling. The production process of cold-rolled seamless steel tube is generally more complicated than that of hot rolling. The tube blank must be first rolled by three rolls, and then be subject to sizing test and cutting after extrusion. Then enter the annealing process. In appearance, the cold-rolled seamless steel tube is shorter than the hot-rolled seamless steel tube, and the wall thickness of the cold-rolled seamless steel tube is generally smaller than that of the hot-rolled seamless steel tube, but the surface looks brighter than the thick wall seamless steel tube, the surface is not too rough, and the diameter is not too much burr.

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 10025-6 high strength steel 1.8904, 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.

Cold rolled EN 10025-6 high strength steel 1.8904 steel sheet can be produced by two high mill, four high reversing mill, multi high reversing mill and tandem cold mill. Although there are still only two work rolls in four high and multi high rolling mills, each work roll is supported by one or more large diameter backup rolls, which can prevent deflection of work roll. As a result, wide and thinner EN 10025-6 high strength steel 1.8904 steel plates can be produced. For example, 20 high mill can produce as thin as 0. 001 mm sheet, but the two high mill can only produce as thin as 0. 35mm sheet

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
