A 13% manganese, 4% nickel – 41⁄2% chromium electrode for joining manganese and building up parts subjected to extreme impact, compression and abrasion. For welding, joining and overlay of manganese to manganese or to dissimilar alloy steels producing a work-hardening weld deposit that takes on “armoring” characteristics. Austenitic manganese weld deposits have extreme resistance to hot-cracking where contraction strains cannot be stress relieved. No limit to the number of layers or passes that can be applied. Weld deposits are non-magnetic and easy to flame cut using an oxyacetylene torch; machining is possible using tungsten carbide tools. Commonly used on quarry and mining equipment such as stone crushers, shovel buckets and teeth, excavator pins, mill hammers, dredger bolts, railroad frogs and cross-overs, and shot blast machines
