Description
ER80S-B6 is used for joining 5% Cr and 1/2% Mo steels such as A336 Gr. F5, A155 Gr. 5 Cr, A335 Grs. P5 and P5b, A217 C5 (cast) and A199/A213 Grs. T5 and T5b. These grades are used for elevated temperature creep service and with corrosion resistance against steam, hot hydrogen gas and high sulfur crude oils. Used primarily in the petro-chemical and refinery industries. A preheat and inter-pass temperature of not less than 350°F should be maintained during welding. 80S-B6 is similar to material previously classified as ER502 in AWS A5.9-93.
