Type
High-alloy tubular wire based on a complex carbide alloy wire for hardfacing against extreme abrasion.
classification
EN ISO
14700: T Z Fe8
Toepassingen

CEWELD® OA 70 Na is based on a nanotechnology concept of the alloy CCrMoNbWB. It forms special carbides for the wear protection coating of exhaust fans, mixer blades, kiln mixers,  furnace chutes, scrapers, screw conveyors and other equipment that is subject to heavy abrasion and erosion at elevated temperature.

(Best weldable with M21 mixed gas)
