Based in the vibrant heart of Kinshasa, Yoane Steel has built a strong reputation as a trusted manufacturer and supplier of high-strength steel. We understand the demanding requirements of major construction and industrial projects across the Congo, which is why we take pride in providing superior EN 10025-2 S690Q sheet and plate. This material is engineered to deliver exceptional performance, offering the robust strength and reliability needed for the most challenging applications, ensuring your structures are built on a foundation of quality and resilience.
The S690Q grade is a high-strength, quenched and tempered steel known for its impressive toughness. In line with the EN 10025-2 standard, it achieves a minimum yield strength of 690 MPa, meaning it can withstand immense forces without deforming. Its chemical composition is carefully balanced with specific levels of carbon, manganese, and micro-alloying elements to guarantee this strength is paired with excellent weldability and impact resistance, even at lower temperatures, making it a truly dependable material.
