JFE 780 LE Plates


Choudhary Metal is a trusted supplier and exporter of High Strength JFE 780 LE Plates in Mumbai, India. JFE 780 LE Plates are low-alloy high-strength steel plates manufactured through TMCP (Thermo-Mechanical Controlled Process) or by the quenched and tempered process. These plates provide exceptional strength and durability, which helps in reducing the overall weight of welded structures while maintaining superior performance.

Excellent Weldability
JFE 780 LE Plates supplied by Choudhary Metal are produced with controlled chemical composition that ensures a low carbon equivalent and outstanding weldability. These plates are ideal for applications where reliable welding performance is essential.

High Notch Toughness
These plates offer excellent notch toughness due to carefully controlled chemical composition and advanced heat treatment processes. The superior toughness ensures structural reliability and resistance against brittle fracture in demanding industrial applications.

Uniform Quality and Smooth Surface Finish
Manufactured under strict quality control on advanced plate mills, JFE 780 LE Plates provide excellent uniformity in mechanical properties, flatness, and surface finish. The slabs are carefully processed, and modern rolling techniques are used to ensure a smooth and clean surface.

Good Workability
With excellent ductility and formability, JFE 780 LE Plates offer good machinability, making them easy to drill, cut, and fabricate for various structural and industrial applications.

Wide Range of Sizes
Choudhary Metal supplies JFE 780 LE Plates in a wide range of sizes, with widths up to 5,350 mm and lengths up to 27,000 mm. This wide availability helps customers reduce fabrication costs and improve efficiency in large structural projects.

Choudhary Metal ensures high quality products, competitive pricing, and timely delivery to meet the requirements of clients across India and international markets.
