Technical Cored welding Wire
data sheet
011121MBA
HARDFACE BNC-O
CLASSIFICATION
EN 14700: T ZFe16
DESCRIPTION
• Tubular wire for self-shielded metal arc hardfacing
• Alloy designed for extreme resistance to high stress grinding abrasion with moderate impact
• The abrasion resistance and hardness are achieved in one layer thus allowing interesting cost saving
• Suitable for service temperatures up to 650°C
APPLICATIONS
The deposit resists abrasion by small particles under high restraint or erosion in gaseous media.
Examples
Screw conveyors, blast furnace bells and screens operating at high temperatures, ceramic augers, sinter breakers,
extractor fans, etc.
