Nihonweld Mouldweld description: NHF-MOULDWELD is suitable for cladding high-grade parent metals like boiler and fine-grained structural steels, quenched and tampered and alloy structural steels. It can also be used to join non-alloy and alloy steels, cast steel, manganese steels, tool steels, die steels, heat-treatable steels. For joining clad plates on the cladding side. Joinings and surfacings are not subjected to any heat treatment. The molybdenum content together with the high contents of chromium and nickel makes the work-hardening weld metal (Brinell hardness up to 350) exceptionally suited for use in dies and mould-making.
