Characteristics of S690Q-brand steel
S690Q is a hot-rolled hardened structural steel that has undergone subsequent tempering treatment and conforms to the EN 10025-6, DSTU EN 10025-6 standard.
Standard: Hot-rolled product made from structural steel. EN 10025-6: Technical delivery conditions for high-tensile structural steel post-tempering and quenching.
Classification: High-grade structural steel.
Product:Fine-grain steel post-quenching and tempering.
S690QL ultra high strength steel - EN 10025
S690QL is a high strength quenched and tempered steel grade that complies to steel specification EN 10025. The designation S690QL refers to a minimum yield strength of 690 MPa.
The combination of good availability and pricing and high strength combined with ease of fabrication has made S690QL steel plate a popular grade for both mobile applications such as cranes and lifting equipment and fixed steel structures. The high strength nature of this steel means that structures can be designed lighter and for mobile application this means increase in payload and operational efficiency.
