Abstract

COLMONOY No. 42SA is a nickel-base alloy recommended for hard surfacing parts to resist wear, heat, corrosion and galling. Deposits have a moderate hardness of Rockwell C 35-40 and can be machined with carbide tooling. Also, deposits have fairly good workability, ductility and impact strength. Colmonoy No. 42SA is supplied as an atomized powder for application with Wall Colmonoy's SPRAYWELD Process. This datasheet provides information on composition, physical properties, hardness, elasticity, and compressive strength as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, joining, and powder metal forms. Filing Code: Ni-227. Producer or source: Wall Colmonoy Corporation.
