This specification covers a low-alloy steel in the form of welding wire.
This wire has been used typically as filler metal for gas-metal-arc or gas-tungsten-arc welding of critical weldments of low-alloy steels requiring a joint capable of being heat treated to a strength level approximating that of the basis metal, but usage is not limited to such applications.
Wire shall be classified as follows:
Type 1 - Bare Wire
Type 2 - Copper Coated
Type 1 shall be supplied unless Type 2 is specified.
