Description

Product Description

HARDFACE CNV-O x 2.0mm

CLASSIFICATION

EN 14700 T Fe16

DESCRIPTION

• 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

Hardface CNV-O 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.
