CROMAROD® DUPLEX B Covered (Stick) Electrodes (SMAW) Stainless

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.
