S690QL / 1.8928 - SteelNumber - Chemical composition, Mechanical Properties and applications

S690QL is a high strength, low alloy structural steel with good weldability and bending properties.

This high yield, high tensile versatile product is often chosen by designers to reduce weight in structures.

S690QL Plate is a high yield strength structural steel grade produced in accordance with EN 10025-6. This steel is designed to provide an excellent combination of high strength, toughness, abrasion resistance and weldability.

Due to the material's high strength nature, using S690QL will promote leaner designed structures with increased payload capacity and energy efficiency.

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.
