welding-alloys.com 9 Thermal fatigue Hot oxidation Corrosion Cutting Work hardening Machining Description and applications u u u u Strong tough austenitic weld metal composition that work hardens. Work hardening rate is lower than 13% Mn steel. Weld metal has excellent crack resistance with high tolerance to dilution. Suitable to use as a buffer layer before hardfacing, particularly on manganese steels and 'hard to weld' steels. Applications: steel mill rolls, tram / train rails and crossings, high speed forming rolls. u u u Non-magnetic deposit highly resistant to impact and pressure. High rate of work hardening. Multi-purpose cored wire. Economic ductile buffer layer prior to hardfacing with chromium carbide cored wires. Applications: repair works on railway frogs and crossings, hammers, bars, cones and jaws for crushers. u u u High rate of work hardening. Austenitic manganese steel deposit strongly resistant to impact and high pressure. Applications: reclaiming crusher jaws and rolls, gyratory mantles, blow bars, swing hammers, manganese dredge components such as buckets and tumblers. u u u Colour and structure of the deposit similar to Hadfield type 13% Mn steel. A buffer layer such as HARDFACE 19 9 6 or HARDFACE AP should be used prior to hardfacing low or medium alloyed steels with HARDFACE NM14. Applications: retouching of casting imperfections, parts undergoing high impact or heavy battering loads. u u u Non-magnetic deposit highly resistant to impact and pressure. Excellent work hardening properties. Applications: rebuilding components exposed to abrasion, high impact and heavy loads. Back to contents page
