Postalloy® 207 Flux-coated Electrode

Postalloy® 207 is a high alloy, work-hardening austenitic manganese steel hardfacing electrode. It can be used equally well for joining and build-up/surfacing of carbon, low alloy and manganese steels. Weld deposits made with Postalloy® 207 are a modified chromium-manganese chemistry providing an excellent combination of weld metal strength and ductility. Work-hardens rapidly under repeated impact. The yield strength is higher than ordinary manganese alloys providing greater resistance to mushrooming when subjected to compressive loads and repeated impact. Ideal as a cushioning or buffer layer on manganese steel parts that must be rebuilt on a repetitive basis. Since it will not embrittle until 1000 °F (538 °C), it will act as an insulator to the manganese base metal in helping it keep below 500 °F (260 °C) during the welding operation.
