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 mDF (816 mDC) and oxidation resistance up to 2000 mDF (1093 mDC), but usage is not limited to such applications.
