Hard, Smooth, Lightweight

    ColWear™ Wear Plates

    REDUCE OPERATIONAL EXPENSE AND PLANT DOWNTIME

    ColWear™ Plates are smooth, crack free, lightweight, have minimal dilution, and provide hardness down to the fusion line.

    Wall Colmonoy’s range of ColWear™ vacuum fused wear plates offer a unique solution to the most aggressive wear problems within high-temperature corrosive, abrasive, erosive environments.  ColWear™ Plates extend service life of components within Oil & Gas, Cement, Steel, Waste to Energy, Mining, Agriculture and many other industries.

    ColWear™ Plates’ lightweight, thin construction from a weldable mild steel or stainless-steel backing plate enables ease of handling, forming and fabrication, and can be used in a wide range of industries and applications.

    As a world leading manufacturer of hard-surfacing alloys, Wall Colmonoy materials have been extending service life of industrial parts for nearly 90 years. ColWear™ Plates protected with Colmonoy® (nickel), Colferoloy™ (iron) or Wallex® (cobalt) hardfacing alloys – last significantly longer than unprotected parts in aggressive service environments – reducing costs, maintenance and downtime.


    Benefits

    ColWear™ Plates coating with Colmonoy® NiCrBSi, Wallex®, or Colferoloy™ CoCrMO powder matrix, with or without Tungsten Carbide (WC).

    • Provide a dense, tough surface resistant to abrasion, erosion and impact
    • Extends equipment service life
    • Reduce downtime, increase uptime

    ColWear™ Plates’ lightweight, thin construction from a weldable mild steel or stainless steel backing plate enables ease of handling, forming, and fabrication, and can be used in a wide range of industries and applications.

    ColWear™ Plates provide a dense, tough surface which is resistant to high-temperature corrosion, abrasion, erosion and impact with excellent ASTM G65 test results.

    Unlike bulk weld overlay wear plates, ColWear™ Plates do not suffer from surface cracking, coarse surface finish or base plate metal dilution.


    Advantages

    • Superior hardness (55-64 HRC), retained down to the fusion line with minimum dilution of base material
    • Excellent abrasion performance
    • Inherent corrosion resistance
    • Good impact and erosion resistance
    • Lightweight and thin – easy to handle, form and fabricate
    • Retained high temperature hot hardness in matrix (45 HRC) – working temperature range up to 650°C
    • Smooth, flat surface, crack free
    • Fully dense pore-free coating
    • Able to precision cut by water jet or laser
    • Weldable back plate
    • Repairable in service (Fusewelder™ Torch)
    • Cost advantage over WC (tungsten carbide) application via HVOF or cloth based cladding.

    Controlled Process

    ColWear™ Plates are produced by the closely controlled process of vacuum fusing the matrix coating to the baseplate, resulting in a homogeneous coating and consistent micro structure, offering matrix hardness in the range of 55 – 64 HRC (other hardness ranges available).

    ColWear™ Plates provide excellent corrosion resistance for both aqueous and hot gas corrosion environments (like in waste-to-energy applications) due to the chemistry of the super alloy matrix.

    ColWear™ Plates can also be manufactured using stainless steel and exotic nickel super alloy base plates for further extension of high temperature capability in corrosive environments.


    Superior Wear Performance

    ColWear™ plates offer superior wear resistance and lifetime well beyond the industry standard. They are a great choice for products with difficult maintenance cycles because they eliminate so much waste and failure.  Customers experience less downtime and far lower maintenance costs.  In tough environments, ColWear™ offers compelling long-term savings.
