Dual Shield 7100SRM
Dual Shield 7100SRM is an all-position flux cored wire that displays exceptional impact properties in both the as welded and stress relieved condition when used with 75% Ar/25% CO2 shielding. The weld deposit has less than 0.5% nickel which conforms to the A-1 composition in ASME Section IX, QW-440.
