Trimay® produces wear-resistant metallic claddings on steel plate and pipe. Our company focus is on the selection and finished quality of our overlays and inlays, providing innovative solutions to our customers, and continual research toward better, longer-lasting alloy-clad products to prevent abrasion, erosion and corrosion in dry, wet and hot environments. Simply put, our wear products are considered top-performing, providing solutions to problems where even carburised (quench and tempered) steels fail quickly; and quality, innovation and research are the guiding principles.

Ensuring quality, lowering costs and promoting stakeholder comradery are the pivoting points of Trimay's researching efforts. The methods involve metallurgic engineering of overlay/inlay chemistries, practical laboratory testing, and field monitoring. We like to build strong relationships which allow for field and laboratory comparison, win-win relationships that fuel our customer-centric philosophy on product development.


Quality is ensured through a number of industry standard procedures designed to test bondability, wear and impact resistance of the overlays. Some tests such as the Charpy V-Notch, or any methods used for tensile strength testing, are quite sophisticated and must be performed on a metal sample from the same piece of steel, before and after the overlaying process. All testing is accomplished via certified third party except the reverse bend test which involves a visual bondment inspection of overlay that has been 'reverse bent' to stretch the cladded face. See the below list for the most common tests used.

  • For 'wet' wear ability: ASTM G75 - 07 Standard Test Method for Determination of Slurry Abrasivity (Miller Number) and Slurry Abrasion Response of Materials (SAR Number).. . click for description

  • For impact resistance: Charpy V-Notch Impact Test. Results before and after are compared to ensure substrate properties are unchanged throughout overlay process... click for description

  • For bondability: a combination of reverse-bend testing and photomicrograph images are used to ensure bonding at the fusion zone (where the overlay dilutes into the substrate).

  • Hardness: Rockwell Hardness (HRC) testing throughout the thickness of the sample piece (generally up to 20 locations) is conducted... click for description



    Trimay® provides customers with an extensive selection of the longest-lasting wear alloys developed to date. Our abrasion-resistant product line extends from traditional chromium carbide and tungsten-based overlays, to complex mixtures for specific hot, corrosive or impact applications. Furthermore, in 2010, a new boron-based cladding alloy (T171) was Developed by Trimay® Wearplate Ltd. using Nano Technology .To put it in perspective, our overlays/inlays are considered top-performing, and provide solutions to all wear problems between carburised (quench and tempered) steels and fire brick.

    Overlay Types


    Trimay® manufactures four primary types of overlays: Chromium Carbide, Complex Carbide, Tungsten Carbide, and Borocarbide-based choices. Some wear better than others and all wear longer than any steel (austenitic, hardened or any other kind). The length that any overlay will last is dependent on the wear environment. The environment varies for each application, thus we strongly suggest viewing our "Choosing Overlays" page before determining what type of overlay you require.
