S690QL ultra high strength steel
Classification :
Keywords: Handheld refractometer
PRODUCT DETAILS
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.
