Arc Welding Service

CATEGORY

TYPE

Fluxcored welding wire for corrosion resistant hardfacing applications

APPLICATIONS

Rebuilding parts that faces wear combined with corrosion and impact.

PROPERTIES

Extreme tough and corrosion resistant weld deposit, well suited for parts that encounter wear from sea water plant and power plant operation. This acid corrosion resistance alloy has a 14% Cr. content combined with 0,3% carbon that results in excellent wear properties.
