Form This specification covers a corrosion and heat resistant steel in the form of welding wire. Application This wire has been used typically as filler metal for gas-metal-arc welding or gas-tungsten-arc of critical weldments of precipitation-hardenable@ corrosion and heat resistant steels of similar composition where the weld area is required to have strength and corrosion resistance comparable to those of the parent metal@ but usage is not limited to such applications. This filler metal provides joints with increased crack resistance over those using AMS5805 wire when welding similar steels.
