HARDCOVER 450
Alloy Type: HARDFACING Core, Bare, and Coated Electrodes
HardCover 450 (HC450) is a hardfacing
electrode well suited for metal to metal wear
applications involving steel, manganese steel
and cast iron. The weld deposits are very
crack resistant and multiple layers are easily
applied for thick build-ups. HC450 is intended
for impact and moderate abrasion.
Typical Applications
• Especially suited for metal wear applications
involving steel, manganese steel and cast
iron.
