ER80S-B6

AWS A5.28 ER80S-B6

80S-B6 is a low alloy Cr-Mo filler commonly used in the oil and chemical industries 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. Controlled preheat, interpass and postheat treatment may be needed. 80S-B6 is similar to the previously classified ER502 in AWS A5.9-93.

USA 80S-B6 (502) is used for welding AISI type 502 stainless steels and 5% chrome moly steels.
