Mechanical properties of S690QL low alloy high strength steel plate

In production and operation, the company always attaches great importance to product S690QL low alloy high strength steel plate quality. Product quality is stable, performance index is superior, after-sales service is in place, the company's products have been exported to the United States, Southeast Asia, Africa, the Middle East and other countries and regions, occupying a large part of the overseas market S690QL low alloy high strength steel plate. And a large number of famous enterprises at home and abroad have formed a solid strategic partnership with the company.

Due to the surge in business volume in recent years. In addition to coordinating our own truck fleet, our logistics department has continuously developed high-quality logistics companies and signed long-term cooperation agreements. While enjoying the professional and fast service of logistics companies, we have significantly reduced transportation costs. That not only ensure our customers receive the goods at the same time, but also help them reduce shipping costs.

Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.

In January 2019, one of our Vietnam customer purchased 395.62 tons Q345B steel plate S690QL low alloy high strength steel plate for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 S690QL low alloy high strength steel plate and priming gray oxide primer, and arrange shipment in time. Meet the customer urgent delivery request.
