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-tungsten-arc or gas-metal-arc welding of corrosion and heat-resistant alloys of similar composition, but usage is not limited to such applications.

The relatively high ferrite content promotes weldability by combating microfissuring and minimizing cracking in heavy sections but limits use of the wire to applications not operating in the sigmaforming temperature range, approximately 1100 to 1600 °F (590 to 870 °C).
