ROYAL PRIME A1 is a low alloy flux-cored wire designed for welding 0.5% Mo creep-resistant steels. It provides good tensile strength, toughness, and creep resistance under elevated temperature service conditions. Typical applications include boilers, pressure vessels, piping, and structural components in power plants and refineries.
