Product Description
HARDFACE AP-O x 2.0mm
EN 14700 T Fe9
DESCRIPTION
• Cored wire for self shielded metal arc hardfacing and build-up
• Austenitic deposit with excellent work hardening properties
APPLICATIONS
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. also suitable as a buffer [build-up] deposit prior to application of a harder hardfacing wire. e.g. HC-O
Examples
Railroad frogs, crusher rolls, hammers, steel mill rolls and all components where a work hardening deposit is desirable.
