BuildHARD® 4400
Open Arc Flux Cored Wire – Hardfacing

 

General Characteristics

BuildHARD® 4400 is an open arc flux cored wire developed for repair, buffer or hardfacing operations of manganese steels (Hadfield type).

Welding procedures should be prepared according to base materials size and geometry. Base material should be allowed to cool down while welding. If base material has complex geometry or large dimensions, welding in a cooling bath will avoid grain growth which cause embrittlement.
