Frequent Replacement = Rising Operational Costs
Critical wear components—such as hopper liners, bin liners, chute liners, and screen plates—often wear out far earlier than planned. This results in constant replacements, increased labor hours, and high spare-parts inventory pressure, directly impacting operational budgets.
Conventional Plates Plateau in Demanding Conditions
NM400/AR400 are reliable for general wear, but in high-abrasion or mixed-impact environments, they quickly reach their limits:
•Faster thinning under continuous sliding abrasion
•Unstable performance when impact and abrasion occur together
•Shorter service life in high-output, 24/7 operations
Even with regular maintenance, wear parts in heavy-duty environments degrade faster than expected. This leads to escalating production costs, unstable performance, and constant operational stress.

WHY CHOOSE OUR CCO WEAR PLATES?
Precision-Matched to Your Wear Challenges
Wear problems are rarely identical—abrasion angles, impact frequency, particle size, and temperature conditions vary widely.
We provide application-driven customization:
• Sliding abrasion / high-impact / high-temperature
• Custom thickness structures (e.g., 6+4 / 8+6 / 10+10 )
• Ready-to-install components: chute liners, hopper liners, silo liners

Consistent Performance Across Every Batch
The true performance of a CCO wear plate comes from metallurgical stability—not just hardness numbers.
Our controlled metallurgical engineering ensures every plate behaves exactly as expected:
• Precise Cr/C ratio control keeps carbide volume fraction consistent across batches
• Batch-to-batch microstructure consistency guarantees predictable wear curves, reducing unexpected downtime

WHERE CCO WEAR PLATES ARE USED
Equipment wear is a core problem that restricts production efficiency and increases operational costs—every shutdown to replace worn parts means production interruption and economic losses.
With the composite advantage of "substrate toughness support + high-hardness wear-resistant surface", hardfacing wear plates can adapt to the complex working conditions of high wear, high impact, and high temperature in various industries.
COMMON MISCONCEPTIONS ABOUT WEAR-RESISTANT STEEL PLATES
COMMON MISCONCEPTIONS ABOUT WEAR-RESISTANT STEEL PLATES
Wear-resistant steel plate is a broad category that includes multiple material systems and various manufacturing processes. Chromium Carbide Overlay (CCO) wear plates represent only one sub-category or a special type within this large family.
CCO wear plate ≠ NM400 / AR400
- • Definition: Quenched & Tempered (Q&T) steel plate.
- • Type: A high-hardness low-alloy steel.
-
NM400 / AR400
-
CCO Wear Plate
- • Structure: Low-carbon steel base + welded overlay layer.
- • Type: A composite plate with a "wear-resistant surface."
Formation Mechanism
-
CCO wear plates are manufactured through hardfacing overlay welding. The process includes the following stages:
-
Overlay Welding
Specialized flux-cored wires are melted and deposited onto the steel base plate. -
High-Temperature Austenitic Phase
Cr and C elements dissolve fully in the austenitic matrix within the molten pool. -
Carbide Precipitation
During cooling, large quantities of primary Cr₇C₃ carbides precipitate and distribute within the martensitic matrix. -
Martensitic Matrix Formatio
Remaining austenite rapidly transforms into martensite (providing high hardness), while a small amount of retained austenite improves crack resistance. -
Metallurgical Bond
The overlay layer is metallurgically bonded to the base plate, forming a high-hardness, high-wear-resistant composite structure.
-
Overlay Welding
Key Performance Enhancements
• Metallurgical bonding prevents delamination.
• High volume fraction of chromium carbides forms a rigid wear-resistant skeleton.
• Directional solidification improves resistance to erosion and abrasion.
