WEAR PIPE
TWP57
TWP57is an iron-based steel overlay wear solution with a unique proprietary chemical composition designed to withstand heavy wear environments exposed to mild-moderate direct impact.
TWP57 is the top-performing chromium carbide wear pipe on the market. It has a smooth surface with extra Chromium and Manganese on its composition.
KEY PERFORMANCE
CHARACTERISTICS
- Heavy abrasion and mild/moderate impact resistance.
- Compatible composition for welding.
- Hardness increase on underlying layer(s).
- Good hardness at elevated temperatures.
Applications
TWP57 is Trimay’s® premium Chromium Carbide alloy and has virtually no competition in the market place. It acheives excellent wear life in highly abrasive environments and exhibits high impact resistance.
Overlay Attributes
TWP57 consistently rates between 56 – 58 HRc for hardness, and only loses 0.13 g (+/-0.03) on ASTM G65-04 Procedure A mass loss test. T157 has a slick drag coefficient of 0.185 to deter material buildup
