80S-D2 is a low alloy designed to produce high strengths on a wide range of base metals such as problem steels containing high sulfur to the basic carbon and low alloy Cr-Mo base metals. Its silicon level with molybdenum and manganese gives you excellent arc stability, low spatter, yielding a flat bead with excellent impact values and high ductile tensile strengths in the 100,000 psi range. 80S-D2 produces X-ray quality and porosity free welds even over poor cleaned base metals – widely use out of position .
