Arc Welding Service

CATEGORY

TYPE

High-alloyed tubular wire on a C-Cr-Nb carbide basis for extreme hard deposits on parts subject to strong mineral abrasion, weldable without protective gas.

APPLICATIONS

Cladding and rebuilding parts that are subject to severe abrasion.

PROPERTIES

Extreme abrasion resistant with reasonable impact properties and temperature resistance up to 300ºC. Due to the combination Cr and Nb carbides the deposit structure contains very fine particles that results in excellent wear resistance against heavy abrasion. Usualy the maximum number of layers is 2 till 3 but when using a special stringer build up technick with release cracks, upto 15 layers is also possible.
