Mac Nicro E217
AWS E Ni Cr Mo 7
Descriptions & Applications:
MMA electrode manufactured on a pure nickel core wire with a chemically neutral, alloy bearing, high purity, concentrically extruded flux coating. Metal recovery is 140% with respect to that of the core wire. Designed for welding Ni Cr Mo base materials such as ASTM B574, B575 and UNS N06455 to itself as well and steel and related cladding operations.
