ROYAL ARCPRO 14

AWS/ASME: A5.17 EH14

ROYAL ARCPRO 14 is a manganese-silicon alloyed submerged arc welding wire classified as EH14.
Designed for welding structural steels, pressure vessels, pipelines, and shipbuilding steels.
Provides higher tensile strength and toughness compared to EM12K.
Delivers high deposition rates, smooth bead appearance, and excellent slag detachability.
Performs well with basic and neutral fluxes in both single-pass and multi-pass welding.
Suitable for low-temperature applications with good notch toughness.
