S890QL steel plate mild steel sheet coils

The BBNSTEEL company has the first-class qualification for steel structure professional contracting, integrating production, design and installation, and can undertake various steel structure projects. The product has a wide surface, flat and smooth surface, and neat trimming. It has users in more than 10 provinces and cities in China and is exported to the United States, Canada, Japan, Europe, Southeast Asia and other countries and regions.

S50C steel characteristics: the carbon content of the steel (mass fraction, %) ≥ 0.4, excellent wear resistance, reduced ductility, easy to deform and crack after quenching, so quenching is extremely important, and it must be quenched after cutting and tempering to avoid tempering brittleness. By implementing spheroidizing treatment, the cutting performance of this type of carbon steel keyword} can be improved. The steel is usually used after tempering to a hardness of 19~22HRC to increase its cutting performance.

XAR450 steel is a special structural steel material with high wear resistance. The average hardness of this special wear-resistant structural steel is 450HB, which has high hardness and good toughness. The structure built with this steel is stronger, lighter and can withstand impact loads. XAR450 steel is used for wear parts-exposed structures such as protective pads, shell walls, support and reinforcement plates for excavators, mining machines and bulldozers.

S355NC steel offers excellent bending, flanging, cold-bordering and folding S890QL steel plate properties in both longitudinal and transverse direction. The bending radii specified below should be observed as minimum values.

S890QL steel plate product plate specification range:
Thickness 3-150mm
Width 1500-4020mm
Length 4000mm-17000mm
Heat treatment: annealing, or normalizing and tempering

Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, S890QL steel plate sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
