M30-Fused Chromium Carbide Overlay

M30 is a chromium carbide overlay plate designed for mining and material handling applications where high sliding abrasion is combined with moderate impact.

M30 is our best-selling and most versatile overlay wear plate, designed to deliver reliable performance across a wide range of sliding wear applications. It features a single-phase chromium carbide alloy deposited onto a mild steel baseplate with tight control over hardness and carbide distribution.

M30 consistently outperforms conventional open-arc CCO overlay plates and quenched and tempered (Q&T) steel in both wear life and surface stability, making it a trusted CCO wear plate for hoppers, chutes, bins, and material transfer points.

It also provides a significant upgrade over traditional hardfaced steel plates, offering better surface finish, crack resistance, and wear predictability in demanding environments.

Benefits

• Maintains strong wear resistance in high-impact environments
• Smooth, crack-free surface reduces the risk of spalling and unpredictable wear
• Reliable choice for chutes, ROM bins, and mobile plant where impact is a key challenge

Surface Benefits of FuseTech Plate

FuseTech smooth chromium carbide overlay plate compared with conventional CCO wear plate showing rough weld beads, uneven surface texture, and material flow differences
1.Eliminates carryback and material hang-up
2.Supports non-directional material flow
3.Enables more predictable wear rate

Unlike conventional CCO wear plates or chromium carbide overlays, which often have uneven surfaces, visible weld beads, and a higher risk of cracking or spalling, the FuseTech wear plate is engineered for reliability in demanding applications.

Our advanced single-pass alloy deposition process (ranging from 5mm to 25mm) eliminates the need for traditional multi-pass welding used in standard CCO wear plates. These older methods frequently result in under-bead cracking and inconsistent wear surfaces. In contrast, the FuseTech plate features a naturally smooth, crack-free finish that supports uninterrupted material flow, reduces turbulence, and prevents material hang-up and carry-back.

This smooth surface not only improves operational efficiency but also leads to a more predictable wear pattern, reduced downtime, and extended service life—making the FuseTech plate a premium alternative to conventional chromium carbide overlay products.

CCO Wear Plate FAQ

1. What makes FuseTech plates different?

Traditional CCO wear plates, typically feature a rough surface with visible weld beads and cracks. In contrast, a FuseTech plate is engineered with a naturally smooth, crack-free finish and consistent thickness. This improves flow efficiency and wear performance, especially in high-throughput or material-handling environments.

Conventional chromium carbide overlay plates often suffer from material build-up due to their uneven surface and weld ridges. A FuseTech plate, by comparison, features a smooth, non-stick surface that reduces carry-back and blockages. This means better material flow, easier cleanout, and less downtime in wet or sticky applications.

While standard clad plates rely on multiple weld passes that leave behind irregular surfaces, FuseTech wear plates are produced using an advanced single-pass welding method that fuses high-chromium alloy powder onto mild steel. This controlled process results in a naturally smooth and consistent surface without the post-grinding often required by traditional overlay products.

FuseTech plates deliver superior performance by combining strong sliding abrasion resistance with enhanced impact toughness. Unlike many traditional surfaced plates that may crack or chip under heavy load, the refined microstructure of a FuseTech plate ensures better durability and longer service life in harsh, high-impact conditions.

With conventional CCO wear plates, visible weld patterns often limit cutting flexibility and nesting efficiency. FuseTech plates eliminate this problem with a smooth, non-directional surface, making them easier to cut, nest, and install. This helps reduce waste, simplify fabrication, and optimize material use across projects.

One of the most common methods is the ASTM G65 dry sand/rubber wheel test, which measures material loss under controlled abrasion. This test helps compare different wear plate materials on a consistent basis.
At Fusetech, our plates are tested both in-house and externally through reputable laboratories such as:
ATTAR (Australian Testing Services for Advanced Research)
TUNRA Bulk Solids (University of Newcastle) 
These tests provide reliable data to validate the plate’s wear life and ensure consistent performance in the field.
