 Description and Applications
 Rutile coated austenitic electrode with stainless steel core wire, for
 welding of dissimilar steels, steels that are not readily weld able and
 14%Mn steel. Also it is recommended for buffer layers on steels prior to
 hard surfacing.
 Distinguished by its outstanding welding characteristics such us excellent
 out of weldability good striking and re striking properties, stable arc, no
 spattering and weld metal showing strain herdanability, excellent
 cavitation resistance, cracking resistance.
 Preheating post weld heat treatment is dictated by the base metal.
