HARDCOVER 430
Alloy Type: HARDFACING Core, Bare, and Coated Electrodes
HardCover 430 (HC430) is a tubular,
self-shielded wire for metal arc hardfacing.
It is an austenitic manganese steel type alloy
used for build-up and reinforcing manganese
steel castings and wear components. It has
excellent work hardening properties. The
degree of work hardening is dependent on
the amount of impact on the rebuilt
component. HC430 should be considered
when rebuilding 14% manganese steel parts.
Typical Applications
• Reclaiming crusher jaws and rolls
• Gyratory mantles
• Blow bars
• Swing hammers
• Manganese dredge components
• Railroad sections
• Bucket teeth and lips
