HARDFACE AP-O
EN 14700 T Fe9
• Cored wire for self shielded metal arc hardfacing
• Austenitic deposit with excellent work hardening properties
Hardface AP-O produces an austenitic and non magnetic weld deposit which has excellent work hardening properties. The degree of work hardening is dependent on the amount of impact on the rebuilt component. It is used for rebuilding components exposed to high impact or heavy loads and can be used on ferritic and austenitic steels including “Hadfield” manganese steel. Deposit can be multi-layered
Examples
Railroad frogs, crusher rolls, hammers, steel mill rolls and all components where a work hardening deposit is desirable.
