S690Q high strength steel plates application. Start from the service conditions and design rules, then check the ordered grade, dimensions and inspection points.
Identify the Q, QL or QL1 suffix, thickness, ordered impact temperature, certificate and permitted fabrication route.
EN 10025-6:2004 Technical delivery conditions for steel plate and sheet of high yield strength structural steel products in the quenched and tempered condition. It covers steel grades of S460 series, S500 series, S550 series, S620 series, S690 series, S890 series, S960 series. EN 10025-6 high strength steel plates have a specified minimum yield strength of 460 MPa to 960 MPa after quenching and tempering.
The material could be warmth treated using quench and temper strategies. S690QL plates have larger payload capability and are energy efficient, hence can be utilized in leaner constructions. This steel is used in other purposes corresponding to heavy transportation, development business, machine building, and lifting tools. We deliver products in customizable options to satisfy customer-specified requirements.
Our products are widely demanded for their robust built and precision finishing. Our products are known to offer amazing usability in all kinds of use.
