Description: AFM E320-16 is primarily used to weld base metals of similar composition, such
as alloy 20, for applications where resistance to severe corrosion is required
for a wide range of chemicals including sulfuric and sulfurous acids and their
salts. They can be used to weld both castings and wrought alloys of similar
composition without postweld heat treatment.
