Postalloy® 53-SPL
Highly machinable. Postalloy® 53-SPL, a solid, gas-shielded welding wire, is designed for joining, build-up and overlaying various types of cast iron, such as ductile, nodular, gray, and Ni-resist. The unique chemistry of Postalloy® 53-SPL provides weld deposits that are fully machinable. Under normal circumstances, if dilution is kept to a minimum, there is no undercutting and weld deposits can be machined through the fusion zone, even with high speed steel tooling.

Welding Procedure:
Gas Coverage: While both Argon and Argon/CO can be used as a gas cover, pure Argon will help this alloy to wet out better on cast iron and produce much better welding characteristics. Postalloy® 53-SPL should be applied in stringer beads with only a slight side to side oscillating motion. All craters should be back-filled. Optimum bead contour is slightly convex. Peening will help to relieve stresses. When welding cast iron preheat will improve machinability and reduce stress caused by welding. Gray, nodular and ductile: 400-500 ˚F (204-260 ˚C) Ni-resist and other alloyed types: 800-1000 ˚F (427-538 ˚C)
