E8018-B6
AWS A5.5 E8018-B6 | ASME SFA 5.5 E8018-B6
8018-B6 (formerly 502 family) is a low hydrogen covered electrode commonly used in the oil and chemical industries, tubes, heat resistant steel and where base metal such as 5% Cr, 1/2% Mo steels are found. Typical base metals found in this group are ASTM grades: A182-F5/F5a, A336-F5/F5a, A199-T-5, A200-T5, A213-T5, A335-P5, A369-FP5, A426-CP5, A217-C5, and A387-Gr5. Our coating yields a stable arc that has low spatter, high deposition, low moisture absorption, with a great re-strike and easy flux removal. As with many Cr/Mo base metal alloys using a preheat and post heat will ensure best quality crack free welds.
