6996-O is mainly used to rebuild components exposed to high impact and corrosion Sub-layer before hardfacing, particularly on manganese steels and “hard to weld” steels Buffer layers for welding on black manganese steel, for welding on hardenable steel and for welding of hardfacings.Hardfacing on rails, switches, tumblers, striking pins, components subjected to thermal stress, e.g. in rockwool production Examples : Steel mill rolls, metallurgical plant guides, tram and train rails and crossings, high speed forming rolls.
