CROMAMIG 2507 deposits a 25%Cr/9%Ni/4%Mo/0.25% N super duplex type
weld metal with a ferrite level of approximately FN 55. It is designed for
welding similar composition steels e.g. SAF 2507, Uranus 52N, Zeron 100,
which offer even higher strength and corrosion resistance levels than the
ordinary duplex grades. CROMAMIG 2507 may also be used for welding
standard duplex steels when higher corrosion resistance in the weld metal is
required. A heat input range of 0.4-1.5 KJ/mm is recommended to maintain a
favourable phase balance in the weld metal and avoid deleterious
precipitation effects in the plate.
