AWS: SFA 5.5 E8015-B6

EN ISO CODE:

It is low hydrogen electrode producing a weld deposit containing 5Cr - 0.5Mo, which has excellent creep resistance at elevated temperatures up to 550 ^oC. The weld metal displays excellent creep resistance with controlled hardness. This electrode is used for welding creep resistant steel and cast steels of similar composition. Typical applications include steam boiler construction, welding of steam and super- heater piping, power plants, Oil refinery and chemical plants.
