Arc Welding Service

CATEGORY

TYPE

High-alloyed tubular wire on a C-Cr-B-W-V carbide basis for extreme hard deposits on parts subject to strong mineral abrasion.

APPLICATIONS

Rebuilding and or protecting wornout parts that faces extreme abrasion attack with medium impact.

PROPERTIES

Very good wear resistance even at higher temperatures. The deposit gives already a very good hardness in the first layer. A buffer layer with OA 4370 or OA MnCr is recommended in case of sensible base material or old layers. Weldable without protective gas.
