Hilchrome 307R is our rutile basic coated electrode for joining dissimilar steels and difficult-to-weld steels. Typical
applications include joining 14Mn steels, spring steels, tool steels, and high carbon steels. This electrode is
recommended for buffer layers prior to surfacing. The deposit weld metal features strain hardenability, excellent
cavitation resistance, thermal shock resistance, crack resistance and scaling resistance up to 850ºC.
Hilchrome 307R is a core wire alloyed all-current type (AC/DC).
