OA 57 FCAW Flux-Cored




OA 57

 
CATEGORY 
TYPE 
High-alloyed tubular wire on a C-Cr. carbide basis for extreme hard deposits on parts subject to strong mineral abrasion.
APPLICATIONS 
Rebuilding and or protecting wear parts against extreme abrasion with low impact.
PROPERTIES 

High C-, Cr- alloyed flux-cored wire electrode which forms extremely hard carbides for extremely hard deposits on parts subject to excessively heavy abrasive wear weldable without protective gas. More than 3 layers should not be deposited. A Buffer layer with OA 4370 or OA MnCr is recommended in case of old layers or critical base metals.. Equivalent in SMAW: Dur 62S
