This specification covers a corrosion and heat resistant cobalt alloy in the form of welding wire. This wire has been used typically as filler metal for gas-tungsten-arc or gas-metal-arc welding of parts fabricated from alloys of similar or dissimilar composition, and as stapling pins requiring high strength up to 1500 °F (816 °C) and oxidation resistance up to 2000 °F (1093 °C), but usage is not limited to such applications.
