Abracrom 904
Highly corrosion-resistant stainless steel electrode
Product description
Rutile-base-coated electrode depositing a steel with an austenitic structure for welding steels of identical grade (Uranus B6).
Molybdenum and copper content give the deposit excellent corrosion resistance in sulfuric and phosphoric media. Good resistance to pitting, crevice and/or stress corrosion, particularly in hydrochloric environments. Service temperature up to 400°C. Mainly used for welding and hardfacing steels of identical grade. Excellent weldability, very smooth melting, good slag release, excellent bead appearance.
Main applications : equipment for the paper and cellulose industries, storage and transport tanks.
N.B.: Uranus B6 is a trademark of CREUSOT Loire.
