Metrode TUF-MET-2NIB description: Fabrication of storage tanks, process plant and associated pipework where good fracture toughness from as-welded joints is demanded down to temperatures in the region of -60ºC. The addition of about 2.5%Ni improves microstructural refinement and tolerance to procedural variations compared to plain CMn weld metal. It also promotes the formation of a stable patina as required for matching the characteristics of weathering steels, and is an alternative to using matching consumables (data sheet A-70).
