Product Overview
S690QL is a high-yield structural steel grade manufactured in compliance with the European standard EN 10025-6. The designation 'S' stands for Structural Steel, '690' indicates a minimum yield strength of 690 MPa, 'Q' refers to the Quenched & Tempered delivery condition, and 'L' signifies that the steel has been impact-tested at -40°C to ensure toughness in low-temperature environments.
The primary advantage of using S690QL is its exceptional strength-to-weight ratio. By utilizing this grade, engineers can design thinner, lighter sections that can carry the same loads as thicker, heavier sections made from conventional steel. This is critical in the manufacturing of mobile cranes, heavy transport trailers, and aerial platforms, where reducing dead weight directly increases the lifting capacity or payload.
Convergence Steel supplies S690QL with complete certification and traceability. The material offers good weldability and can be processed using standard techniques, provided that heat input is controlled to maintain the mechanical properties of the heat-affected zone.
