Type
High-alloyed tubular wire on a C-Cr-Nb-W-V carbide basis against schock and abrasion.
classification
EN ISO
14700: T Fe8
DIN
8555: MF 6-55-GP
Applications

CEWELD OA 56 Nb is a self- shielded crored wire for high pressure resistant hardfacing. With the additional Nb carbides they have a good resistanc against abrasive wear.

Rebuilding and hardfacing wornout parts that faces heavy shock and abrasion at the same time.

Cement crush rollers, Pulverizer Rolls, Hammers

Properties

Very good wear resistance against abrasion combined with impact. The deposit gives already a very good hardness in the first layer thank to the Nb carbides. The choice for the buffer layer is depending on the base metal and not always necessary. If applied correctly the hardfacing layer wil not show any cracks.
