Postalloy® CF-28


Postalloy® CF-28 is a high hardness, Chromium free hardfacing overlay designed for high abrasion applications with minimal impact. The unique wear properties are derived from a network of Boron Carbide and Nickel in a hard carbon/iron matrix. Abrasive wear properties are similar to traditional Chromium Carbide alloys of similar hardness. This alloy has excellent weldability with a very smooth bead when used with any common shielding gas. CF-28 is self-fluxing and has no any slag when used without a shielding gas.
