Nitrogen bearing open arc wire for cladding of continuous casting rolls
Beschrijvingen & toepassingen
Nitrogen bearing open arc wire for cladding of continuous casting rolls.
Nitrogen-containing 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
The fully martensitic microstructure provides outstanding tempering resistance, wear resistance, excellent response to thermal fatigue and stress corrosion cracking.
Extensively used as a cladding alloy for rebuilding various steel mill rolls subject to repetitive thermal stresses, corrosion and metal-to-metal wear.
Examples
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...
