| Overlay Description: T161 is a iron-based steel overlay wear solution with a unique alloy composition designed to resist heavy wear under extreme temperature. This is Trimay’s complex carbide overlay that deters corrosion and protects against abrasion even in extreme heat. Overlay Attributes: T161 consistently rates between 60-62 HRc for hardness, and only loses 0.11 g (+/-0.03) on ASTM G65-04 Procedure A mass loss test. The mixture of Chromium Iron, Niobium and Vanadium, plus Trimay’s Sub Arc Welding process, forms a tight crystalline structure, giving T161 the ability to resist corrosion and heavy wear between temperatures of 450o C & 650o C. Common Application: T161 is primarily used for hot or corrosive wear environments. The Oil and Gas, Concrete and Power Industries are primarily where T161 is used. A variation of the T161, the T161i, has added nickel and is used for moderate-heavy impact environments. Information provided by Trimay® |
