Abracrom 4462
Stainless steel duplex electrode
Product description
Rutile-base coated electrode depositing a steel with an austenitic-ferritic (duplex) structure.
The deposit is characterized by very good resistance to pitting, crevice and/or stress corrosion (particularly in the presence of chlorides), combined with very good mechanical tensile strength. Service temperature can reach 250°C. Mainly used for welding and hardfacing steels of identical grade. Excellent weldability, very smooth melting, self-detachable slag, excellent bead appearance.
Main applications: tanks, centrifuges, pumps, piping
