Description

POSTALLOY® 2825-MCG with RCT™ Reactive Core Technology**

POSTALLOY® 2825-MCG is a non-cracking carbide containing martensitic hardfacing alloy for improved abrasion and impact resistance compared to standard general purpose hardfacing alloys. POSTALLOY® 2825-MCG works especially well on dirty contaminated surfaces. Weld deposits are smooth and free of any slag. An excellent choice for applications requiring crack-free deposits with good wear characteristics. Use on carbon and low alloy steels.

** RCT™ Reactive Core Technology improves weldability and optimizes wear properties.
