FCW CNV
Tubular wire for self shielded metal arc hardfacing
Beschrijvingen & toepassingen
• Tubular wire for self shielded metal arc hardfacing
• Highly-alloyed chromium cast iron with a high concentration of complex carbides
• High chromium cast iron for hardfacing components subject to extremely severe abrasive wear and moderate impact up to 600°C.
APPLICATIONS
FCW CNV is designed to give a weld deposit of particularly high hardness and wear resistance on account of the dispersion of complex carbides it contains. This gives superior performance compared to standard chromium cast irons. The properties are reached in only three layers and relief checking is normal.
Examples
Used for crushing, riddling, blast furnace hoppers and throats, ovens, extractor fans etc.
