Fine grained martensitic complex carbide for exceptional abrasion resistance in low impact and erosive applications.


MC3 is a composite wearplate consisting of a hard abrasion resistant surface layer fused to a structural steel backing plate. The refined hyper-eutectic microstructure in the overlay provides excellent wear resistance against a wide range of wear mechanisms in erosive applications.

Base Material

The standard steel substrate is compliant with AS3678 GRADE 250 steel or an equivalent in thickness ranges from 6-12mm. Other grades can be supplied upon request.

Overlay Material

The overlay material is a martensitic chromium carbide alloy consisting of a uniform, high density distribution of fine primary M7C3 carbides in a matrix of carbide, martensite and austenite as described in with AS2576.

Our Quality

MC-3 Wear plate has been developed using Australian technology and applying a ‘customer-orientated solution’ rationale. By assessing the key features of traditional chromium carbide overlay products, processes and even quench and tempered steels in successful abrasive wear applications, a discriminating production process was designed to produce a chromium carbide overlay that pushes beyond the application limitations of existing products.
