View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.Inco-Weld Filler Metal 686CPT is a welding product with higher (Cr + Mo + W) content than most other nickel-base welding products. This higher alloy content increases the resistance to pitting, crevice, and general corrosion. Applications include welding many CRA materials for corrosive service.
