S690QL steel properties prices in China have room for increase in the short term

High-strength wear-resistant steel plates such as S690QL steel properties are mainly used in the construction machinery industry to manufacture wear-resistant working parts and structures for excavators, loaders, bulldozers, graders, coal machines, large off-highway dump trucks, electric wheels, mining, docks, cement Equipment parts such as factories and steel mills that need to be worn and washed in the material transportation link.

Good impact resistance. Wear resistant composite steel plate uses low carbon steel or low alloy, stainless steel and other toughness as the base material. The S690QL steel properties metal material not only has good wear resistance, but also can withstand the impact and wear of falling from high to low in the transportation process. It has good heat resistance. Vanadium, molybdenum and other S690QL steel properties alloy materials are added into the alloy wear-resistant layer during the manufacturing process, so it can be used and worn at high temperature ≤ 800 ℃. Compared with ordinary S690QL steel properties carbon steel substrate, it can only be used below 380 ℃, while low alloy heat-resistant steel plate can work below 540 ℃. This shows how high the heat resistance coefficient of wear-resistant steel plate is. Good corrosion resistance.

Laser cutting S690QL steel properties has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the S690QL steel properties cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.
