CCO Hardfacing Screw Flights: The Ultimate Defense Against Severe Abrasion
Stop replacing your screw conveyors every few months. Switch to Chromium Carbide Overlay (CCO) protection.
In high-impact and high-abrasion environments, standard carbon steel or stainless steel flights fail prematurely. Our CCO Hardfacing Screw Flights are engineered with a specialized chromium-rich alloy layer, providing a hardness rating of HRC 58-65. This ensures your equipment stays operational 5 to 10 times longer than untreated alternatives.
Why Choose CCO Hardfacing?
Standard “wear-resistant” steels like AR400 offer baseline protection, but they cannot match the metallurgical bond of a CCO overlay. Our process involves depositing a high-chromium alloy onto a tough base metal, creating a surface that thrives under the most brutal conditions.
- Drastically Reduced Downtime: Fewer change-outs mean more uptime for your processing line.
- Lower Total Cost of Ownership: The initial investment is offset by the massive reduction in maintenance labor and replacement part costs.
- Customizable Patterns: We offer chevron, diamond, and cross-hatch welding patterns to optimize material flow and prevent “hang-ups.”

Industry Applications
Our hardfaced flights are the gold standard for moving “hostile” bulk materials:
- Mining & Aggregate: Iron ore, quartz, sand, and gravel.
- Cement & Construction: Clinker, slag, and raw meal handling.
- Power Generation: Bottom ash, fly ash, and biomass fuel.
- Waste Management: Glass recycling and abrasive municipal waste.
The Gamp Advantage
- Precision Engineering: Every flight is laser-cut and CNC-formed to ensure a perfect fit for your existing shaft.
- Quality Assurance: We perform ultrasonic testing (UT) and hardness verification on every batch to ensure zero delamination.
- Rapid Turnaround: We maintain a large inventory of base plates to get your custom-hardfaced flights out the door and into your machine faster.
