Why Choose Chrome Carbide Overlay (CCO) Wear Plates for Industrial Use?
Chrome Carbide Overlay (CCO) is engineered for extreme sliding abrasion where even AR500 steels and ceramic tiles fail early. Each industrial wear plate or pipe section carries a hypereutectic Fe‑Cr‑C weld deposit packed with primary M₇C₃ carbides (62–64 HRC) that sit on a tough, ductile steel base. This micro‑duplex architecture delivers:
· 5–6× longer wear life than quenched‑and‑tempered AR400/500 in ASTM G65 testing.
· Impact resilience – the mild‑steel backing absorbs shock loads that shatter monolithic ceramic liners.
· Thermal stability to 1000°F (538°C) – perfect for clinker, coal and ash handling.
· Easy fabrication & field repair – plasma‑cut, roll to a 4 in (100 mm) radius, then plug‑weld or bolt in place for fast change‑outs.
· Lower total cost of ownership – fewer shutdowns, reduced labor hours, smaller spares inventory with Chrome Carbide Overlay.
At a Glance Comparison
| Challenge | AR Plate | Ceramic Tile | Hardfacing Rod | WC700Plus™ CCO |
|---|---|---|---|---|
| Abrasive fines & dust | ★★ | ★★★★★ | ★★ | ★★★★★ |
| Moderate Impact | ★★ | ★ | ★★ | ★★★★ |
| Field weld / bolt repair | ★★★ | ★ | ★ | ★★★★ |
| High temp (>800 °F) | ★ | ★★ | ★★ | ★★★★ |
| Tight‑bend layouts | ★★ | ★ | – | ★★★ |
With Chrome Carbide overlay, uptime climbs, maintenance windows shrink, and crews stay safer (no in‑situ gouging, no silica break‑out). Pair WC700PPlus pipe or HyperClad™ smooth plate when flow‑ability is critical—the same carbide toughness, zero hang‑ups.
Chrome Carbide Overlay Product Family Table
| Variant | Base Metal | Overlay / Thickness | Typical Use-Cases |
