Cromarod Duplex B is a basic flux coated electrode intended for welding similar composition duplex stainless steels e.g. 1.4462, UNS 31803. The basic coating design produces a very low micro-oxide level in the deposit, giving excellent fracture toughness at temperatures down to -46 °C. Duplex stainless steels offer an excellent combination of high strength and very good resistance to chloride induced pitting and stress corrosion cracking. A heat input range of 0,5-2,5 kJ/mm is recommended to maintain a favourable ferrite/austenite phase balance in the weld metal.
