Luke Steel, based in Houston, Houstan, is a reliable manufacturer and supplier of top-notch JFE 780 LE sheets and plates, serving industries like automotive, construction, transportation, and heavy engineering. Known for their high-strength, low-alloy steel solutions, Luke Steel guarantees that every JFE 780 LE plate meets rigorous international standards for strength, weldability, and formability. With cutting-edge production capabilities, thorough quality checks, and reliable delivery, Luke Steel is here to support customers who need lightweight yet durable steel for applications where high yield strength, longevity, and excellent forming properties are essential for performance and safety.
JFE 780 LE sheets and plates are crafted from high-strength, low-alloy steels that include micro-alloying elements such as niobium, vanadium, and titanium, which help improve grain refinement and strength. They usually contain about 0.10–0.20% carbon, along with controlled amounts of manganese and silicon to enhance weldability and toughness. These plates boast a minimum yield strength of 780 MPa and tensile strength ranging from 830–950 MPa, along with impressive impact toughness and formability. Their well-balanced composition and fine microstructure ensure dependable performance in parts that need a high strength-to-weight ratio and good cold forming capabilities.
