Cromarod 312 is a rutile flux coated electrode which deposits a 29%Cr/9%Ni austenitic/ferritic stainless steel weld metal with a ferrite content of approximately FN 50. The weld metal exhibits excellent tolerance to dilution
from dissimilar and difficult-to-weld materials without hot cracking.
Applications:
– Difficult-to-weld steels e.g. high carbon hardenable tool, die and spring steels, 13% Mn steels, free-cutting steels, high temperature steels(non-structural).
– Dissimilar joints between stainless and high carbon steels.
– Surfacing of metal-to-metal wear areas, hot working tools, furnace components.
