JFE Everhard 450 Wear Resistant Steel Plate

What is the production process of JFE-EH450?

The Jfe steel process involves steelmaking → continuous casting → heating → rolling → quenching + tempering (quenching and tempering) → finishing.

What kind of heat treatment process is adopted for the JFE-EH450 Carbon Wear Steel Plate?

Quenching + Tempering (quenching and tempering)

Why can the JFE-EH450 Carbon Wear Tahan Steel Plate Suppliers（JBLstainless） thick plate maintain its hardness even inside?

The key lies in the design of high-quenching alloy (containing elements such as Mn, B, Mo, etc.) combined with industrial-grade water quenching process, which ensures that the center of thick sections can also be rapidly cooled to form uniform martensite/bainite structure.

How does JFE control the plate shape and dimensional accuracy?

The JFE wear-resistant plate is controlled to shape through the Super-CR super control rolling technology, the frame-type ultra-fast cooling system, the CVC roller profile optimization and the high-precision feedback model. The dimensional accuracy is guaranteed by the precise rolling load distribution and the online thickness measurement closed loop.

What is the tolerance for JFE EH 450 thickness?

+0.8mm/0mm or ±0.3mm ~ ±0.5mm

In which industries is the JFE-EH450 mainly applied?

Mining machinery, construction machinery, material conveying equipment

Why choose JBL stainless JFE-EH450?

The reason for choosing the JFE-EH450 core lies in its high wear resistance of 430-470HB and its high strength and toughness with a yield strength of ≥ 900MPa. This significantly extends the service life of wear-prone components in construction machinery and reduces the total cost over the entire cycle.

Which is better, the Japanese JFE-EH450 or the domestic NM450?

For extreme conditions/high reliability, JFE-EH450 is the preferred choice. For regular heavy-load and cost-sensitive scenarios, the domestic NM450 offers a better cost-performance ratio.

Why is the price of JFE EH 450 so high?

The high price of EH450 is mainly due to the fact that it is a high-hardness wear-resistant steel plate produced by the Japanese JFE Steel Factory. The core factors driving its high price are the import tariffs/logistics costs, the special alloy formula and heat treatment process, the excellent comprehensive performance (high hardness + high toughness + weldability), as well as market supply and demand.

What are the differences between imported EH450 wear-resistant plates and domestic EH450 wear-resistant plates?

Imported EH450 (usually referring to the original brand name of Japan’s JFE) and the domestic version without the “EH450” brand name, in fact, is a product of the same level as NM450.

Can EH450 replace Hardox 450?

EH450 (usually referred to as JFE-EH450) can replace Hardox 450 in most conventional wear-resistant applications.

Can EH450 replace AR450?

NO
