FCW 414DN-S
Tubular wire for submerged arc cladding steel mill rolls
Description & applications
Tubular wire for submerged arc cladding steel mill rolls.
Nitrogen-containing specially designed 13% Cr martensitic stainless steel weld deposit optimised for corrosion resistance.
The alloy has high hardness and excellent wear and galling resistance.
Ferritic-martensitic stainless steel weld deposit with excellent resistance to thermal fatigue.
Applications
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, steam turbine components, valve seats, valve gates, valve wedges, safety valves etc.
