S690QL Steel

S690QL steel is a high-strength, quenched and tempered structural steel known for its exceptional toughness and capacity to withstand heavy loads and impacts. It has a minimum yield strength of 690 MPa, making it suitable for demanding engineering applications like cranes, bridges, and heavy machinery. This steel is designed to be tough, durable, and resistant to fracture, even at elevated temperatures, while also offering good weldability under controlled conditions. Its advanced properties enable safety and performance in critical structural components where strength-to-weight ratio is essential.
