High-strength heavy plates - alform® and aldur® - Weight savings combined with excellent weldability
aldur 700 Q
Our quenched and tempered high-strength aldur®-steels are used in highly sophisticated welded constructions. Weight reduction and reliabilty in operation at deep temperatures are very important goals.
aldur®-steels are mainly used for mobile cranes and vehicles, mining and high-pressure pipes as well as for offshore applications.
Advantages
- Higher tensile strength in comparison with common structural steels result in weight reduction. In the field of mobile cranes and vehicles higher payloads are possible. Cost efficient constructions give additional benefit.
- Excellent weldability as a result of low carbon equivalents: high resistance against cold cracks in the heat affected zone (HAZ), lower preheating temperatures in processing and high reliability of components due to high toughness in the welded seam.
