Description: AFM ER409Cb is the same as ER409 except that columbium (niobium) is used instead
of titanium to achieve similar results. Oxidation losses across the arc are
generally lower. It is used to weld 409 stainless steel. The greatest usage is
for applications where thin stock is fabricated into exhaust system components.
