Austenitic Mn steels and Austenitic CrMn steels have the ability to rapidly work harden under impact loading, which makes them a great solution for a number of applications.
Cored wires with a high content of alloying elements (e.g. HARDFACE 19 9 6 and HARDFACE AP) are easily applicable and their weld metal deposits are well known for their high tolerance to dilution and cracks. Thanks to these properties, they can be deposited directly to low or medium alloy substrates, with no risk of forming a martensitic structure at the interface.
Their multi-purpose nature makes them an ideal choice for a number of applications (build up, buffer layer or hardfacing).
Products that have a similar chemical analysis to Hadfield 13% Mn steels must be applied with care. This is due to their intrinsic susceptibility to embrittlement when exposed to interpass temperatures higher than ~150°C.
Their resistance to gouging abrasion is exceptional and unique, but special care should be adopted when applying these types of cored wires.
