| Overlay Description: T170 is at the top of Trimay’s product list. T170 is a nickel-based steel overlay wear solution with a unique proprietary alloy composition designed to withstand heavy impact and severe wear environments. T170 is unrivalled in wear resistance and impact resistance. The T171 (numerically higher only because it is Trimay’s latest attempt to match T170 performance in a lighter, more economical fashion) tries, but falls short. Overlay Attributes: T170 consistently rates between 46 - 50 HRc for hardness, and only loses 0.05 g (+/-0.03) on ASTM G65-04 Procedure A mass loss test. T170’s Nickel Chrome Iron Matrix (NCIM), with Macrocrystalline Tungsten Carbide (MTC) and other elements added, forms this wearable nickel-based alloy. Furthermore, because MTC carbides do not degrade throughout the overlay application process, the finished overlay keeps ductility and is able to absorb impact rather than fracture. Common Application: T170 is used in intense wear environments, most commonly in areas exposed to frequent direct impact and intense wear. It is always economical. Information provided by Trimay® |
