Welding Solution manufactures premium Chromium Carbide Overlay (CCO) Wear Plates for extreme industrial durability. We use a mild steel (MS) base plate and hard-face it with a high-alloy overlay. Our process utilizes open-arc welding with high-chromium welding wire to create a superior metallurgical bond.
Superior Protection and Cost Efficiency
This advanced bonding process offers a cost-effective alternative to traditional abrasion-resistant steels. Furthermore, our plates provide maximum protection against abrasion, erosion, corrosion, and impact. Consequently, maintenance teams can rely on Welding Solution to extend the lifespan of their critical machinery.
How to Install and Fabricate CCO Plates
We design our plates for easy integration into existing systems. Therefore, your team can quickly implement these solutions to minimize downtime.
Versatile Mounting Options
Specifically, engineers can weld, bolt, or stud the wear plate onto existing structures. Because our plates remain versatile, they fit a wide variety of industrial frames. Additionally, fabrication shops can form, roll, and cut the plates to meet complex geometric requirements.
Best Practices for Joining and Cutting
To achieve the best results, operators should follow specific guidelines. For instance, we recommend joining the plates using 309/312 weld wire or rods. Moreover, workers must roll the plates in the direction of the weld beads to maintain structural integrity. Regarding fabrication, our materials respond perfectly to Plasma, air arc, and water jet cutting systems.
Welding Solution 600: Standard Protection
We developed the 600 series as the industry standard for general-purpose wear protection. This series suits applications involving high abrasion but low to moderate impact.
Technical Performance of the 600 Series
Our team produces these plates via open-arc welding using flux-cored hard-facing wires. Typical installations include chutes and ducts.
| Feature | Specification |
| Hardness | 58-62 HRC |
| Heat Resistance | Up to 400°C |
| Typical Applications | Chutes, ducts, mining equipment |
| Chemical Composition | C: 3.0-5.0% | Cr: 15.0-35.0% |
Welding Solution 650: High-Impact Resistance
In contrast to the standard series, the Welding Solution 650 targets environments with heavier material flow. Consequently, this plate provides a thicker protective barrier for high-wear zones.
Where to Use the 650 Series
Specifically, we recommend this grade for heavy-duty material handling. It handles moderate impacts effectively while maintaining high surface hardness.
| Feature | Specification |
| Hardness | 58-65 HRC |
| Heat Resistance | Up to 450°C |
| Typical Applications | Buckets, hoppers, scrapers |
| Chemical Composition | C: 3.0-5.0% | Cr: 25.0-45.0% |
Welding Solution 700: Complex Carbide Technology
For the most demanding industrial environments, we offer the 700 series. We enrich this plate with Niobium (Nb) to combat severe abrasion and complex wear patterns.
Advanced Engineering for Harsh Conditions
This composite wear plate utilizes flux-cored wires to ensure a dense, hard surface. As a result, it excels in applications like impellers and severe-duty liners where standard plates might fail.
| Feature | Specification |
| Hardness | 57-63 HRC |
| Heat Resistance | Up to 550°C |
| Typical Applications | Impellers, liners, severe-duty chutes |
| Chemical Composition | C: 4.0-6.0% | Cr: 20.0-28.0% | Nb: 3.0-4.5% |
Welding Solution 750: Extreme Heat Solutions
Finally, our 750 series represents the pinnacle of wear technology. Because we use a unique alloy blend of Vanadium (V), Tungsten (W), and Molybdenum (Mo), this plate maintains its hardness in extreme heat.
Survival in High-Temperature Zones
Specifically, we recommend the 750 series for applications reaching up to 650°C. Therefore, it remains the primary choice for exhaust fan blades and clinker cooler plates in cement plants.
| Feature | Specification |
| Hardness | 62-65 HRC |
| Heat Resistance | Up to 650°C |
| Typical Applications | Fan blades, clinker coolers, screens |
| Chemical Composition | C: 4.0-6.0% | Cr: 22.0-25.0% | Nb: 5.0-7.0% |
Global Manufacturing Standards
We maintain strict quality control across all production lines. Currently, we offer a standard cladding area of 1300 x 2800 mm using high-grade structural steel as the base.
Available Thicknesses and Industry Support
Additionally, we provide several thickness configurations to meet your needs:
- Standard Sizes: 5+3 mm, 6+4 mm, 8+6 mm, and 10+8 mm.
- Customization: We also offer custom configurations upon request.
Targeted Industries
Welding Solution CCO plates are the trusted choice for:
- Mining & Quarrying
- Cement & Steel Plants
- Power Generation
- Glass Manufacturing
A: While AR steels like AR400 or AR500 are through-hardened, Welding Solution CCO plates offer significantly higher hardness ($58$-$65$ HRC) and can last $5$ to $10$ times longer in high-sliding abrasion environments. CCO plates feature a metallurgical bond between the hard-faced overlay and a mild steel base, making them more cost-effective for extreme-wear zones in mining and cement industries.
A: Yes. Depending on the series, our plates are engineered for extreme heat. The Welding Solution 600/650 series handles up to 450°C, while our Welding Solution 750 Complex Carbide series is specifically designed for high-heat zones like clinker coolers and exhaust fans, maintaining integrity at temperatures up to 650°C.
A: These are known as “relief cracks” and are a normal, beneficial characteristic of the hard-facing process. They occur during the cooling phase to relieve internal stress. At Welding Solution, we ensure these cracks only exist in the overlay and do not penetrate the base metal, allowing the plate to be formed and rolled without structural failure.
A: For maximum structural integrity, always perform primary welds on the mild steel base plate. Welding directly on the hard-faced surface can cause brittle joints. We recommend using 309/312 stainless steel consumables for joining and then “capping” any exposed joints or bolt heads with Welding Solution hard-facing wire to ensure 100% wear protection across the surface.
A: By extending equipment lifespan by over 200%, Welding Solution CCO plates significantly reduce the frequency of part replacements. This leads to lower steel consumption, reduced carbon footprint from manufacturing, and less industrial waste, helping mining and power plants meet modern sustainability and ESG (Environmental, Social, and Governance) targets.
