US: Martin Engineering has launched its bimetallic wear plate product Arcoplate around the world. Originally the wear plate was sold only in Brazil by the bulk handling products firm.
Martin Arcoplate uses a chromium carbide-rich metal alloy face plate with a steel back plate to resist gouging, erosion, temperature extremes and material build-up. It is marketed for excessive wear and material accumulation issues with bulk material handling. It is available in three grades. Alloy 1600 is designed for high abrasion and high impact applications. Alloy 1040 is engineered for moderate impact and cyclic temperatures up to 500°C. Alloy 8668 is suitable for extreme temperature applications, with cycles up to 700°C. Each derives its abrasion resistance from the M7C3 carbides (1500 - 1800Hv), with an average of 60% carbide dispersed through a softer, tougher matrix.
Arcoplate is manufactured by Alloy Steel International in Malaga, Australia.
