Electrodes for Creep Resisting Steels
CROMOTHERME-5L
AWS: SFA 5.5 E8018-B6L
EN ISO CODE: 3580-A ECrMo5 B 4 2 H5
Low carbon, low hydrogen, iron powder producing a weld deposit containing 5Cr - 0.5Mo, which has excellent creep resistance at elevated temperatures up to 550°C. The weld metal displays excellent creep resistance with controlled hardness. The lower levels of carbon limit in weld metal ensuring higher ductility. Ideal for welding steels of similar composition. Typical applications include welding of 4 - 6% Cr steels in oil refinery, chemical plant and equipment.
