FCW 250-O
Tubular wire for self-shielded metal arc hardfacing
Description & applications
Tubular wire for self-shielded metal arc hardfacing.
Surfacing or rebuilding parts subjected to high compression stresses and high impact.
FCW 250-O is used as buffer layer on ferritic steels before hardfacing with wires providing higher abrasion resistance or for rebuilding.
