Processing Guide
Due to their high strength and toughness, EN high strength steel plates require suitable processing methods to maintain material performance.
Cutting
Appropriate cutting methods should be selected according to plate thickness and accuracy requirements. Proper heat control during thermal cutting helps maintain dimensional stability.
Welding
Suitable welding procedures, consumables and heat input control are recommended to ensure weld quality and reduce the risk of defects.
Bending & Machining
Higher strength grades require suitable bending radius and machining parameters to minimize stress and maintain component performance.
