Q: What is JFE-HITEN 780LE?

It is a 780 N/mm² class high-strength plate from JFE Steel with high weldability and excellent toughness at −40 °C, listed in thicknesses of 5–160 mm (and 160.1–203.2 mm at 610 MPa yield).

Q: Is JFE 780 LE the same as S690QL?

No. It is a Japanese JFE grade of 685 MPa minimum yield and 780–930 MPa tensile strength. It is used as a comparable alternative to S690QL where the design allows it.

Q: What sizes are listed?

Widths up to 5,350 mm and lengths up to 27,000 mm are listed, with separate availability tables for plate with and without heat treatment.

Q: Can JFE 780 LE be welded?

Yes, with low-hydrogen consumables and the preheat and interpass temperatures the mill gives for the grade and combined thickness.

Q: Which certificate should I request?

An EN 10204 3.1 mill test certificate showing the brand and grade, heat number, chemistry and mechanical properties, plus impact results where you specify a test temperature.

Q: Can another brand replace JFE 780 LE?

Brands of the same class are comparable, not identical. Chemistry, toughness, thickness range and processing advice differ by mill, so confirm any substitution with your engineer.

Q: Can JFE 780 LE plate be cut to size?

Yes. Champak Industries lists full and part plate and profile supply and a plasma-cutting service; send drawings, quantities and tolerances with your enquiry.

Q: Which sizes are available?

Availability depends on the grade, mill and thickness; send the thickness, width and length you need and sizes will be confirmed at quotation.

Q: How do I get a price and delivery date?

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.

Source of the text: This page reproduces JFE Steel’s HITEN catalogue, with the mill’s name replaced by “Champak” in places. Statements such as “because Champak offers high strength” describe the JFE-HITEN plate made by JFE. Words run together in the original (“Good WeldabilityJFE…”) are headings: Good Weldability, Excellent Notch Toughness, Excellent Uniformity and Clean Surface, Good Workability and Wide Range of Sizes.

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.
