Described is a new flux-cored wire PP-AN204 that provides deposited metal of the type of maraging steel with the Fe-Ni-Mn-Si-Mo alloying system. Hardness of the as-deposited metal is HRC 20–30, which allows its easy cutting, while after tempering its hardness grows to HRC 50. After tempering, the deposited metal is characterised by high hot hardness, thermal stability and wear resistance in friction of metal on metal at increased temperatures. Therefore, it can be recommended for hardening of working surfaces of complex-configuration die tools.
Keywords: arc surfacing, deposited metal, maraging steel, flux-cored wire, hot hardness, wear resistance, heat resistance
