OA WC2-Fe FCAW Flux-Cored




OA WC2-Fe

 
CATEGORY 
TYPE 
Iron based flux cored wire for hardfacing containing a high amount of fused tungsten carbides.
APPLICATIONS 
This fused tungsten carbide based alloy provides an excellent resistance against extreme abrasion wear. OA WC2-Fe can be applied on most type of steels except on cast iron or Mn-steel. This alloy is the most wear resistant type in almost any hardfacing application.
PROPERTIES 

2400 HV Iron and Tungsten based hardfacing alloy containing 52-58% (depending on wire diameter) tungsten carbides. OA WC2-Fe  has good welding characteristics. Multi-layer deposits are not recommended due to the extreme high hardness. Fused tungsten carbide will guaranty a long life for several wear applications. Best to be used without gas protection (self shielded).

CLASSIFICATION
