Q690C steel plates are mainly used in heavy machinery, marine engineering, metal structures. BBN STEEL cooperated with Wugang to produce Q690C steel for use in its enterprise production and construction projects. The prospects for produts exporting to the United States, Canada, Australia, India, and Europe are promising. More than 10,000 tons A709 Gr HPS100W bridge steel plate products have been directly supplied to European customers.
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 A709 Gr HPS100W bridge steel plate high-quality, timely and perfect steel products and services under the guidance of the mission of "striving for perfection to meet customer needs".
Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium A709 Gr HPS100W bridge steel plate carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some A709 Gr HPS100W bridge steel plate alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.
The alloying principle of low alloy high strength steel is mainly to improve the strength of steel by solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements. At the same time, the effect of reducing the ductile brittle transition temperature of steel by fine grain strengthening is used to counteract the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that the A709 Gr HPS100W bridge steel plate, low alloy high strength steel can obtain high strength while maintaining good low temperature performance.
As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality A709 Gr HPS100W bridge steel plate products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
