Description
AWS: SFA 5.4 E320-16
EN ISO CODE: 3581-A E Z R 3 2
D&H 320 (NS) is a rutile type non-synthetic all position electrode depositing 20Cr - 35Ni - 2.5Mo - 3.5Cu - Nb weld metal. The weld metal has excellent resistance to oxidation and scaling at 1200 C continuous service. Quiet and stable arc. Less spatter loss good bead appearance with equal ripples. It is primarily used to weld base metals of similar composition for applications where resistance to severe corrosion is required for a wide range of chemicals including sulfuric and sulfurous acid and their salts. These electrodes can be used to weld both castings and wrought alloys of similar composition without post weld heat treatment. The typical applications include HV-9A stainless steel, for fabricating carpenter 20 stainless steels etc.
