Form

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

Application

This wire has been used typically as filler metal for gas-metal-arc or gas-tungsten-arc welding of critical weldments of lowalloy steels requiring a weld joint capable of being heat treated to a strength approximating that of the parent metal, but usage is not limited to such applications.

Classification

Wire supplied to this specification is classified as follows:

Type 1 - Bare

Type 2 - Copper Coated

Type 1 shall be supplied unless Type 2 is specified.
