Mac Nicro E202
AWS E Ni Cr Fe 2
Descriptions & Applications:
A superior electrode for welding nickel alloys similar to Incoloy 800, Incoloy DS and Brightray to stainless steels and Cr Mo creep steels. For welding 3% to 5% nickel and 9% nickel steels for semi and full cryogenic applications and for welding high temperature cast alloys such as HK40.
