Description:
Cromarod Duplex-140 is a rutile flux coated high deposition electrode with 140% recovery. It
complements the normal recovery electrode Cromarod Duplex and is primarily intended for welding
medium to heavy sections of duplex type stainless steels, e.g. W. 1.4462, SAF 2205, Uranus 45N. It
can also be used for the lower alloyed duplex types W. 1.4362, SAF 2304 and Uranus 35N. The
electrode is easy to use and produces smooth weld beads, slightly concave profile fillets and
easy-releasing slag. A heat input range or 0.5-2.5 KJ/mm is recommended to maintain a favourable
austenite-ferrite phase balance.
