Postalloy® 305 Flux-coated Electrode
Postalloy® 305 is a non-cracking electrode designed to weld low alloy, high strength steel such as T-I, Hy-90, Hy-100, SSS-100. An all-position electrode that provides crack-free welds under highly stressed conditions with outstanding elongation and ductility. Easy slag removal.
- Flux-coated Electrode
- Used to fabricate tanks, containers, covers, and high strength pipe.
- Use for welding low alloy steels containing manganese, nickel, molybdenum, and chromium such as I-beams, angle iron, scaffolding and super structures.
- Weldments can be used as welded or stress relieved.

Preheat is unnecessary when welding low carbon steels. A preheat of 400-600 °F (204-316 °C) is recommended when joining heavy sections to thin sections and low alloy or higher carbon steels are welded. Maintain a short arc and use stringer or weave beads. Allow deposit to cool before chipping off slag. Heat to 1025 °F (552 °C) and maintain for 1 hour to stress relieve.
