JFE Steel Co. pioneered the production and sale of abrasionresistant steel plate in Japan in the mid-1950s, and JFE abrasion-resistant steel plate (JFE EVERHARD) enjoyed widespread use as a vital material for construction, mining, civil engineering and farming equipment. Furthermore, JFE Steel Co. has succeeded in developing super abrasion-resistant steel plate EH-SP with higher abrasionresistance than that of the Brinell 500 grade, and EH360LE, EH400LE, EH500LE with excellent toughness through the leading edge of production technology. Those products enjoy customer's reputation.
In this catalog, we would like to introduce the JFE EVERHARD series of abrasion-resistant steel plate.
Mill text: Several paragraphs on this page come from JFE Steel’s own literature, so “we”, “our” and “our customers” refer to JFE Steel, not to Champak Industries.
Grades covered: The text describes the whole JFE EVERHARD series; this page is for EH400 plate. “Abrasionresistant” means abrasion-resistant.

A variety of available grades
A total of 9 grades are available ; the standard series and the alloy series with 3 and 2 grades of hardness respectively, a new super abrasion resistant grade, as well as 360 grade, 400 grade and 500 grade with high toughness, providing a complete product line that can meet a wide range of applications.
Standard Series
This series consists of grades produced with the main emphasis on their hardness levels, the chemical composition being basically simple with boron added while the additon of other alloying elements is restrained.
Alloy Series
This series contains alloying elements in greater quantities than the standard series. The prescribed hardness is guaranteed for plate thickness of up to 100mm and, at the same time, carefull consideration has been given to low-temperature toughness.
Super Abrasion resistant plate EH-SP
Customers often call for the development of a longer-lasting abrasion-resistant plate in order to reduce running cost. However up to now, it has been difficult to develop an abrasion resistant plate that performs better than the conventional 500 grade plate, without reducing the plate's weldability and formability. Our new higher abrasion resistant plate succeeds in doing this.
Abrasion- resistant steel plate wi th excellent toughness EH360LE, EH400LE, EH500LE
High toughness at -40˚C of abrasion-resistant steel plate was generally difficult to be guaranteed. JFE has succeeded in developing abrasionresistant steel plate including 500 grade with excellent toughness guaranteed at -40˚C. EH360LE, EH400LE and EH500LE are the most suitable plates when high toughness is required because of the application in low temperature environment and/or suffering with high impact. EH360LE has also high resistance to weld cracking, then presents high quality and safety of welded joint.
Superb quality
JFE's abrasion-resistant steel plates are produced at modern Works. Based on many years of experience, production incorporates the latest in heat treatment technology and proceeds under strict quality control. The result is high-quality steel plate that offers not only outstanding abrasion-resistance but good weldability and workability as well.
JFE EVERHARD is manufactured for non-structural steel plates which are specified by chemical analysis of molten steel, Brinell hardness at the plate surface and material toughness. It is not specified and guaranteed by its tensile strength and elongation which are required to be specified as structural steel plates. In case of any request for the tensile strength and/or elongation as reference, please refer to JFE Steel Technical Bulletins.
Choosing JFE EH 400 (JFE, Japan Make)
JFE EH 400 (JFE, Japan Make) is in the 400 HBW hardness class. Higher hardness generally lasts longer against sliding abrasion but is harder to bend, cut and weld; where parts also take heavy impact, a tougher, lower class can last longer.
| Class | Nominal hardness | Typical use | Forming and welding |
|---|---|---|---|
| 400 (this page) | About 400 HBW | Dumper bodies, chutes, hoppers, screens | Cold bending and welding with normal care |
| 450 | About 450 HBW | Buckets, liners and heavier wear parts | Larger bending radii; preheat thicker sections |
| 500 | About 500 HBW | Cutting edges, crusher and severe-abrasion liners | Limited forming; strict cutting and welding procedures |
Other JFE EH classes
Brands of the same class are comparable, not identical; confirm any substitution with the end user. See all brands on Wear Resistant Plates.
Applications for JFE EH 400 (JFE, Japan Make)
Typical uses include construction, mining, civil-engineering and farming equipment. Tell us the abrasive material, impact level and the life of the current part so the right class can be quoted.
Cutting, Fabrication and Welding
Champak Industries describes full and part plate/profile supply and a plasma-cutting service. Thermal cutting softens a narrow edge zone, and thick or hard plate may need preheat before cutting. Weld with low-hydrogen consumables and the mill’s preheat and interpass limits; do not heat the plate above the mill’s tempering limit. See AR Plates for bending and drilling guidance.
Testing, Inspection Documents and Traceability
| Requirement | What to identify in the order |
|---|---|
| Mill test certificate | EN 10204 3.1 showing brand and grade, heat number, chemistry and hardness |
| Impact test | Charpy test temperature and minimum energy, if required |
| Traceability | Heat and plate number transferred to cut pieces |
