Chemical composition of S690QL standard sheet structural

Speaking of S690QL standard steel plates for engineering sites, the first thing people think of is wear plates. With excellent wear resistance, wear plates successfully replace traditional aluminum alloy wear plates, which can be called raw materials that are very resistant to wear at this stage. However, with the deepening of winter, the temperature is getting lower and lower, and the wear plates are not resistant to low temperature, so what aspects should be paid attention to in the winter wear plates construction?

Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the S690QL standard steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.

Hot rolled S690QL standard steel coil and plates are among our main products. Hot rolling can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the S690QL standard processing properties of metals and alloys, that is, the coarse grains in the casting state are broken, cracks are obviously healed, casting defects are reduced or eliminated, the as cast structure is transformed into deformed structure, and the processing properties of alloys are improved.

The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, steel structure products, and intimate S690QL standard after-sales service to customers. I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! The company sincerely hopes to establish a long-term cooperative relationship with them, mutual benefit and common development. Welcome to come and visit our S690QL standard steel mill.

With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel S690QL standard product quality.
