Our company was founded in 2000, which initially committed to providing high-quality steel S900MC high strength steel auto plate products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export S900MC high strength steel auto plate steel to the international market, opening up the international steel market.

EN10025-6 S690 steel is a quenched and tempered high-strength non-alloy steel plate. The series of grades are S690Q, S690QL, and S690QL1. They are in accordance with the European standard EN10025-6. The steel specified in this standard can be used for the production of hot-rolled plates with steel grades S900MC high strength steel auto plate, S460, S500, S550, S620, S690, S890, S960 series steel plates with a minimum nominal thickness of 3mm and a maximum nominal thickness of ≤150mm.

Special boiler steel is derived from carbon structural steel, S900MC high strength steel auto plate. The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.

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 S900MC high strength steel auto plate, low alloy high strength steel can obtain high strength while maintaining good low temperature performance.
