Why choose this cored wire?
-
Excellent resistance to extreme impact
➤ Ideal for parts exposed to severe impact, crushing or continuous hammering. -
Significant strain-hardening effect
➤ Austenitic deposit that hardens with use: low initial hardness (~200 HB), but can reach 45-55 HRC under the effect of impact. -
Very good toughness and absence of cracking
➤ Highly ductile deposit, ideal for parts undergoing severe deformation without breaking. -
Multi-passing possible without risk
➤ Deposited metal can be accumulated in multiple layers, even on complex or thick geometries. -
For use on Hadfield and low-alloy steels
➤ Excellent compatibility for repairing or protecting manganese steel equipment.
