JFE EH 400 500 Plates: What makes them great? Learn why they are super tough steel!

JFE Everhard (EH) 400 and EH 500 are high-performance, abrasion-resistant steel plates developed by JFE Steel Corporation. These plates are engineered to provide extended service life in applications subject to severe wear and abrasion, with nominal hardness levels of 400 HBW and 500 HBW respectively.

Key Characteristics of JFE EH 400 & EH 500

Both JFE EH 400 and EH 500 steel plates offer a range of beneficial properties:

  • Superior Abrasion Resistance: Designed to withstand harsh abrasive environments, significantly reducing wear and tear on equipment.
  • Good Weldability: Despite their high hardness, these steels can be welded using appropriate low-hydrogen consumables and preheating procedures.
  • Formability: They offer reasonable formability, allowing for bending and shaping, though considerations for higher hardness, especially with EH 500, are necessary.
  • Excellent Toughness: Engineered for good impact resistance alongside high wear resistance.
  • Uniform Properties: JFE’s advanced manufacturing processes ensure consistent mechanical properties throughout the plate.

JFE EH 400

JFE EH 400, with a nominal Brinell hardness of 400, provides an excellent balance between wear resistance and workability. It is often selected for applications requiring good impact toughness combined with significant abrasion resistance. Common uses include dump truck liners, hoppers, and chutes where moderate to heavy wear is anticipated. Many industries rely on reliable suppliers, such as Shanxi Luokaiwei Steel Company, for sourcing quality wear plates for such demanding applications.

JFE EH 500

JFE EH 500 boasts a higher nominal Brinell hardness of 500, offering superior resistance to wear in extremely abrasive conditions. This grade is ideal for applications where the primary concern is maximizing service life against severe abrasion, such as cutting edges, crusher liners, and wear liners in mining and quarrying equipment. Processing EH 500 requires careful attention to cutting and welding procedures due to its increased hardness.

Processing and Fabrication

Processing JFE EH 400 and EH 500 plates, including cutting (plasma, laser, or oxy-fuel), welding, and bending, requires adherence to recommended guidelines to maintain their mechanical properties. Preheating before welding is often crucial, particularly for EH 500 and thicker sections of EH 400. Utilizing experienced fabricators or consulting with material specialists, like those associated with distributors such as Shanxi Luokaiwei Steel Company, can ensure optimal results.

Typical Applications

The applications for JFE EH 400 and EH 500 are extensive across various industries:

  • Mining and Quarrying: Liners for excavators, shovels, crushers, screens, and conveyors.
  • Construction: Dump truck bodies, bulldozer blades, concrete mixer drums, and paving equipment components.
  • Recycling: Shredders, balers, and sorting equipment parts.
  • Cement and Concrete: Chutes, hoppers, and mixer components.
  • Agriculture: Plowshares, harvesters, and feed handling equipment.

The selection between EH 400 and EH 500 depends on the specific wear conditions and desired service life. For particularly challenging environments, some end-users prefer the extended lifespan offered by EH 500. Companies like Shanxi Luokaiwei Steel Company often stock various grades to meet diverse customer needs.

Sourcing and Availability

JFE EH 400 and EH 500 plates are available globally through authorized distributors and steel service centers. Thickness and plate dimensions can vary, so it’s advisable to consult with suppliers for current stock and delivery options. For projects requiring specific cut-to-size pieces or fabricated components, working with a knowledgeable supplier is beneficial. Reputable stockists, including entities like Shanxi Luokaiwei Steel Company, can provide valuable information on availability and processing. Some suppliers, such as Shanxi Luokaiwei Steel Company, may also offer technical support for material selection and fabrication.
