The Tribology Paradigm: Understanding Chromium Carbide Overlay (CCO) Performance

Industrial machinery components operating within mining, bulk handling, steel production, and power generation sectors are continuously subjected to localized destructive forces. These surface degradation phenomena, principally sliding abrasion, solid particle erosion, and high-load impact, lead to premature component failure, unplanned downtime, and considerable financial loss. Standard carbon steels and even quenched-and-tempered (Q&T) alloys often fall short when confronting severe sliding abrasion.

Tangshan Runxing Machinery’s premium Bimetallic Chromium Carbide Overlay (CCO) Wear Plates are metallurgically designed to address these environments. By utilizing a high-efficiency open-arc or submerged-arc cladding process, we deposit a hyper-eutectic alloy containing a high volume fraction of primary M7C3 chromium carbides (with micro-hardness exceeding 1500 HV) onto a tough structural backing plate (such as ASTM A36, Q235B, or Q355B carbon steel).

"The primary M7C3 carbide phase, characterized by its hexagonal rod-like geometry, acts as a primary barrier against micro-cutting mechanisms from incoming sharp abrasive particles, while the tougher iron-rich matrix absorbs localized impact loads."

Technical FAQ & Design Guidelines for Wear Plates

What is the exact chemical composition range of Runxing CCO Wear Plates?
Our standard chromium carbide overlay (CCO) wear plates typically feature carbon content between 4.0% and 5.5% and chromium content between 22.0% and 30.0%. In high-stress or extreme wear environments, we can adjust the alloy chemistry to include manganese, silicon, and other carbide formers. This composition yields a dense volume fraction of primary M7C3 carbides (typically 30-45%) within a tough eutectic austenitic matrix, resulting in bulk hardness levels of 58-62 HRC.
Why do surface cracks appear on CCO wear plates, and do they affect performance?
The visible cracks on the overlay surface are tension-release cracks that occur naturally during the cooling phase of weld deposition. They relieve thermal stress and prevent deformation or separation of the overlay from the base plate. These cracks are confined to the hardfacing layer and do not extend into the structural backing steel. They do not degrade the plate's wear resistance or mechanical performance under sliding abrasion.
What base steel plate options do you offer for OEM/ODM fabrication?
We offer several base plate grades to meet varying structural requirements. Our standard option is Q235B (equivalent to ASTM A36 / S235JR), which provides good weldability and ductile support. For applications requiring higher strength or toughness, we also offer Q355B (equivalent to S355JR), high-strength structural carbon steels, and heat-resistant steel grades.
How are CCO plates fabricated, cut, and welded in the field?
Due to the high hardness of the overlay layer (up to 62 HRC), standard mechanical sawing is not effective. CCO plates must be cut using plasma arc cutting, laser cutting, or high-pressure water jet processes, cutting from the backing plate side toward the overlay. To install the plates, they can be welded from the structural backing steel using conventional low-hydrogen electrodes (such as E7018), or secured using countersunk bolts and stud-welded attachment points on the back.
Can Chromium Carbide Overlay plates be cold-rolled or bent for curved structures?
Yes, our bimetallic composite wear plates can be cold-formed using heavy-duty industrial roll benders. When rolling with the overlay on the inside (concave), the relief cracks compress. When rolling with the overlay on the outside (convex), the relief cracks open slightly; in some cases, these can be filled with matching wear-resistant electrodes. The minimum bending radius depends on the plate thickness: for a 6 on 6 mm plate, the minimum rolling radius is typically 200 mm to 300 mm. Please refer to our engineering specifications for exact limits.
How does Runxing manage quality control and verify wear resistance?
Our quality control process includes raw material chemistry checks, hardness testing across multiple points on the plate surface, ultrasonic inspection to confirm the bond between the overlay and backing plate, and regular ASTM G65 dry sand/rubber wheel abrasion testing. The ASTM G65 test measures material volume loss to ensure our plates meet specified wear-resistance benchmarks.
What are the maximum operational temperature limits for your CCO wear plates?
Our standard chromium carbide overlay plates are suitable for continuous operation in temperatures up to 350°C. For high-temperature applications, such as blast furnace parts or sinter plant discharge systems, we can modify the overlay chemistry with elements like niobium, tungsten, or vanadium. These specialty grades maintain their structural stability and hardness in environments reaching up to 600°C.
What is the advantage of using Runxing's automatic welding equipment for roller rebuilding?
Our automated welding systems feature four-gun multi-electrode configurations controlled by a central CNC system. This design helps maintain uniform weld bead shape, control heat input, and prevent thermal distortion of the grinding roll or table. Rebuilding worn rolls with our automated equipment helps restore original geometry, prolongs the service life of grinding mills, and reduces overall maintenance costs.
How does the partnership between Runxing and Hebei Yuwan International Trade function?
To ensure clear business processes, all manufacturing, technical development, and quality inspections are handled at our Tangshan facility. All international trade transactions, export licensing, custom documentation, logistics coordination, and financial processing are managed by Hebei Yuwan International Trade Co., Ltd. This division of responsibility allows our manufacturing team to focus on technical quality and on-time delivery.
What information is needed to request a customized quote?
To provide an accurate quote, please provide the thickness specifications (such as backing steel thickness and overlay thickness), total plate dimensions, quantity required, and your application details (such as operating temperature, impact levels, and type of abrasive material). If you require custom fabrication, please share your technical drawings (CAD or PDF formats) showing any cutting, bending, or bolt-hole requirements.
