Electrodes for Nickel and it's Alloys
D&H 1225(NS)
AWS: SFA 5.11 ENiCrCoMo-1
EN ISO CODE:
A non-synthetic Inconel type of electrode, depositing weld metal of Ni-Cr-Co-Mo alloy. The weld metal has excellent crack resistance. Electrodes are used for welding similar type of alloys to themselves and to steel and for surfacing steels with Ni-Cr-Co-Mo weld metal. The electrodes are also used for applications where optimum strength and oxidation resistance is required above 820 deg C & up to 1150 deg C, especially when welding on base metal of Nickel-Iron-Chromium alloys. Specially recommended for welding furnace heating elements, reformer tubes etc.
