ER80S-D2 is a mild steel TIG rod used in situations where porosity is a problem or when you must counter high-sulfur or carbon content in your base metal. It contains high levels of manganese and silicon to provide good wetting as well as good rust and scale tolerance.
In addition to high amounts of Silicon and Manganese, this wire is alloyed with 0.50% Molybdenum, which produces weld deposits with high ductility, excellent impact values and tensile strength.
ER80S-D2 is often used on AISI 4130 where strengths of plain carbon wires are inadequate.
Typical Applications: x-ray quality applications, high-strength welds, steam boilers, pressure tanks, gas pipes, heat exchangers, petrochemical industry
