This specification has been declared NONCURRENT by the Aerospace Materials Division, SAE, as of July 2009. It is recommended, therefore, that this specification not be specified for new designs. NONCURRENT refers to those specifications which have previously been widely used and which may be required for production or processing of existing designs in the future. The Aerospace Materials Division, however, does not recommend these specifications for future use in new designs.

This specification covers a low-alloy steel in the form of welding wire.

This wire has been used typically as filler metal for gas-tungsten-arc and gas-metal-arc welding of steels of similar composition which may be heat treated after welding, but usage is not limited to such applications.
