This specification has been declared “NONCURRENT” by the Aerospace Materials Division, SAE, as August 2008. 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-carbon steel 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 low-carbon and low-alloy steels, but usage is not limited to such applications.
