AWS A5.5 E8018-B8 | ASME SFA 5.5 E8018-B8 F-4, A=5
8018-B8 (formerly 505 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 9% Cr, 1% Mo steels are found. Typical base metals found in this group are ASTM grades:A182-F9, A336-F9, A199-T9, A200-T9, A213-T9, A335-P9, A369-FP9, A426-CP9, A217-C12, and A387- Gr9. Idea for high pressure hydrogen service . 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.
