Material S690QL spec Chemistry

High-strength wear-resistant steel plates such as S690QL spec 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.

The company adheres to the people-oriented concept and takes "learning, sharing, gratitude, integrity, respect and responsibility" as the enterprise values. Advanced equipment, scientific standardized management, strict quality assurance system and high-quality team are the core competitiveness of the company. The company will continue to provide customers with S690QL spec high-quality, timely and perfect steel products and services under the guidance of the mission of "striving for perfection to meet customer needs".

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This S690QL spec production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate S690QL spec size.

Oxygen is a harmful element in S690QL spec steel. With the increase of oxygen content, the strength of S690QL spec steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of S690QL spec steel.

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.
