Postalloy® 206HD Tubular Electrode

Postalloy® 206HD is a high chromium-nickel-moly alloy electrode that produces deposits with excellent strength and elongation, combined with a high degree of toughness. Weld deposits work-harden in service and provide outstanding impact resistance. The austenitic structure of the weld deposit provides very good corrosion resistance. It's versatility allows it to be used for joining, as well as a cushion layer prior to hardfacing with a harder, more wear resistant alloy. Use on carbon and alloy steels, stainless and joining dissimilar combinations.

Welding Parameters

Current Type : DC Electrode Positive , AC

Amps Diameter
90-130 1/8" (3.2mm)
125-160 5/32" (4mm)
150-225 3/16" (4.8mm)

Welding Procedure:

Clean weld area. Maintain a short to medium arc. Direct the arc on deposited weld metal depositing 3 to 4" at a time (76.2-101.6mm). Skip welding is advisable on large parts. Peening while hot helps shape the deposit and reduce stress. Cool slowly.
