How important is the leveling process to S890QL hardness

Our 1810mm production line successfully rolled 1.2mm × 1250mm ultra-thin specifications S890QL hardness high strength automotive steel, and the product quality and performance fully met the standards. In recent years, customers have become increasingly demanding for lightweight vehicles. Our company aims at the market and focuses on the development of thin-gauge high strength automotive S890QL hardness steel. The research and development personnel adjusted the product composition based on theoretical calculations and drawing on other experiences to meet customers' higher requirements for automotive steel yield strength and tensile strength.

After more than 20 years of ups and downs in the steel industry, BBN company's customers have covered South America, North America, Europe, Africa, Southeast Asia and the Middle East and other countries and regions. We treat every customer who inquires with us sincerely, whether you cooperate with us or not, we will provide you with the best quality steel solutions. Our company team also support the online customer service.

There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products S890QL hardness are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.

In addition to our own truck fleet, we also have long-term cooperation with certain logistics companies to ensure that we can deliver S890QL hardness goods in time and smoothly. At the same time, because of the long-term cooperation and huge shipping volume, we can get a good transportation price and save transportation cost for the company and customers. Meanwhile, we have Shipping Department to arrange shipping work in advance. So as not to waste time on transportation both in land and on the sea.

Oxygen is a harmful element in S890QL hardness steel. With the increase of oxygen content, the strength of S890QL hardness steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of S890QL hardness steel.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate S890QL hardness EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
