BuildHARD® 4300
Open Arc Flux Cored Wire – Hardfacing


General Characteristics

BuildHARD® 4300 is an open arc flux cored wire provides corrosion resistance and thermal shock resistance up to 850 ‘C. Austenitic non-magnetic weld metal work hardens depending on the impact.

Weld metal is suitable for ductile buffer layers on old hardfacings also for joining dissimiliar and difficult to weld steels and impact load parts. Work hardening and anti-magnetic.
