AWS A5.1: E7018-1 H4R
Hobart 718MC is a high-performance extra low hydrogen electrode, with low moisture absorption rate, good arc starting and stability, excellent wetting action, easy to remove slag, which is easy to use in all welding positions, and very low spatter levels. This electrode weld metal exhibits very high impact toughness values up to -46°C and is CTOD tested, hence welding of very heavy thickness can be planned with this electrode where extra high toughness requirements are preferred like in Offshore and pressure vessels. This electrode conforms to ASME BPVC Section II part C SFA 5.1 AWS E7018-1 H4 R and E7018 H4 R, and can be used for steels with UTS upto 490 N/mm2 and impact toughness up to -46°C where low hydrogen (H4) compliance and low moisture absorption requirements are preferred. Offshore, Pressure Vessels, Piping, Steel Structures, Petrochemical plants can make use of this electrode.
