CHROMECORE 414MM-S

CLASSIFICATION

EN 14700 T Fe7

DESCRIPTION

• Tubular wire for submerged arc cladding steel mill rolls
• 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.
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.
