FCW 414MM-S
Tubular wire for submerged arc cladding steel mill rolls
Description & applications
The alloy has high hardness and excellent wear and galling resistance.
Ferritic-martensitic stainless steel weld deposit with excellent resistance to thermal fatigue.
Extensively used as a cladding alloy for rebuilding various steel mill rolls subject to repetitive thermal
stresses, corrosion and metal-to-metal wear.
Typical applications include cladding of continuous caster rolls and certain rolls used in hot rolling
applications.
Preheat prior to welding and slow cooling after welding is often essential with this alloy. In some instances,
stress relieving of the components is advisable.
