Product description
Basic type flux cored wire for welding thick steel sections and dynamically loaded structures, where high toughness is required. Provides high mechanical properties and high crack resistant weld metal. Suitable to welding of boiler, tank, pressure vessel, heavy machine production and heavy constructions. Weld are metallurgically clean and are of X-ray quality. Suitable for welding high carbon steels and buffer application on worn parts before hardfacing.
