S690 (Q/QL/QL1) Structural Steel

Henan Bebon Iron and Steel is a professional manufacturer of S690 (Q/QL/QL1) structural steel.
1. Ultimate Performance: Born for Demanding Conditions
* Strength Definition: "The name S690 directly stems from its minimum yield strength of 690 MPa. This means that, under the same load-bearing requirements, its strength is more than twice that of ordinary Q345 steel."
* Toughness Guarantee: "It is particularly important to note that QL in S690QL represents the quenched and tempered delivery condition, which ensures that the steel not only has ultra-high strength but also excellent low-temperature impact toughness. It can easily cope with impact, fatigue, and low-temperature environments, greatly improving the safety and reliability of equipment."
2. Core Value: Lightweighting Brings Full-Chain Benefits
* Weight Reduction Benefits: "By using S690, the structural weight can be significantly reduced by 30%-50%. This is not just a saving in the material itself, it brings a series of chain values:"
* For mobile equipment (such as cranes, mine cars): It means higher payload, lower energy consumption (longer battery life), and better maneuverability.
* For fixed structures: It means smaller foundation loads, simpler support structures, and lower transportation and lifting costs.
* For all equipment: It means stronger product competitiveness in the market.
