Postalloy® INLAY 93

Postalloy® Inlay 93 is a gas-shielded iron base high carbon tool steel cored wire that is capable of producing single and multiple layer weld deposits comprised of a large volume of extremely hard multi-Carbides surrounded by a Martensitic matrix. Deposits perform well under low and high stress abrasion and show dramatic improvements over traditional Chromium Carbide products. It was developed to be used in the Weld Inlay process, (Patent Pending) and may be used with carbon, low alloy, AR, T1 and manganese steels. Unlike Chromium Carbide Alloys, Inlay 93 deposits are heat-treatable, allowing for tougher weld metal for applications that encounter moderate impact.
