CROMAROD® 2507R is a rutile flux coated electrode which deposits a 25%Cr/
9.0%Ni / 4.0%Mo / 0.25%N super dupex type stainless steel weld metal with
a ferrite content of approximately FN 57. The electrode 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. 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 unfavourable precipitation effects in the plate.
