BuildHARD® 4200
Open Arc Flux Cored Wire – Hardfacing


General Characteristics

BuildHARD® 4200 is an open arc flux cored wire developed for repair, buffer or hardfacing operations of low or high alloy steel parts with work hardening properties against heavy impact, pressure and friction.

Fully austenitic structure, tough with strong tendency to work-hardening under pressure and shock. Machinable only with carbide tools or by grinding.
