Hard Facing

JACKSUN ARMOUR 550R

AWS: E1-UM-60GR

JACKSUN ARMOUR 550R is a high-chrome, high-carbon hard-facing electrode designed for extreme abrasion and moderate impact applications.
It provides a high hardness deposit, suitable for wear surfaces exposed to sliding and gouging wear, such as crusher jaws, chutes, and hoppers.
