Abracrom 25/35 H
High temperature stainless steel electrode
Description & applications
Basic coated austenitic stainless steel electrode with 26%Cr, 35%Ni, 1.2%Nb and an increased carbon contend. Used to weld austenitic heat resistant alloys, centrifugally cast tubes etc. resisting to scaling and oxidation up to 1200°C. Regular and stable fusion, good slag removal, nice aspect of the bead.
Main applications:
Petrochemical industry, for welding centrifugally cast pyrolysist coils, reformer tubes, piping systems.
