KOVET-309L is a titania type electrode. The weld metal contains more Cr, Ni alloy than KOVET-308L. The alloy in the weld metal makes austenite structure which contains suitable quantity of ferrite. It has high temperature and corrosion resistibility. It is particularly good for the welding of dissimilar metals, hardening alloy steel, mild steel, low carbon clad steel, SUS 309S and 13Cr Steel.
