Description
AWS: SFA 5.4 E33-31-16
EN ISO CODE:
Secheron 33/31 is a rutile coated electrode, depositing 31Ni - 33Cr - 1.6Mo with Nitrogen and low carbon stainless steel weld metal. This electrode is ideally suited for welding Nickel-Chromium-Iron alloy UNS R20033 to itself, and to weld to carbon steel. It is also suitable for welding ASTM B625, B649, B366, B472, B564, B619, B622, and B626 alloys . The electrodes are generally used in the flat position.
