JFE 780 LE Plates

High Strength JFE 780 LE Plates is low-alloyed high-strength steel plate manufactured by TMCP, or quenched and tempered. Because Champak offers high strength, it results in a significant reduction in the weight of welded structures. Good WeldabilityJFE 780 LE Plates of which chemical composition is controlled by specific procedure offers low carbon equivalent and excellent weldability.

Champak Industries also supplies welding materials suitable for JFE-HITEN effectively, and thereby enjoys acceptances by customers. Excellent Notch Toughness JFE 780 LE Plates offers high notch toughness because it is produced by closely controlling the chemical composition and heat treatment conditions. Application of Champak Industries ensures construction of structures providing high reliability against brittle fracture. Excellent Uniformity and Clean Surface Rolled on the most modern plate mill under rigid quality control, JFE 780 LE Plates has excellent uniformity in properties, flatness and surface finish. In addition, slab surfaces are carefully scarfed, powerful water jets are used during rolling, and nonoxidizing atmosphere furnaces are used for heat treatment. Consequently, JFE 780 LE Plates has smooth and clean surfaces. Good Workability Because JFE 780 LE Plates features good ductility, it offers not only good formability, but also good machinability, making it easy to drill and cut. Wide Range of Sizes JFE Plates are available in widths of up to 5,350mm, and in lengths of up to 27,000mm, and then contributes to saving expenses.
