ER80S-B6 (502)

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.

ER80S-D2

ER80S-D2 is a mild steel solid wire that contains 1/2% Mo for increased strength and high levels of manganese and silicon to provide good wetting and good rust and scale tolerance. It will give radiographic quality welds with excellent bead appearance in both ordinary and difficult-to-weld carbon and low alloy steels. 80S-D2 is suitable for single and multiple pass welding of carbon and low alloy steels and higher strength steels in the as welded and postweld heat treated conditions. It exhibits excellent out of position characteristics with the short circuiting and pulsed arc processes.

ER80S-Ni2

ER80S-Ni2 is a mild steel solid wire that contains over 2% Ni. It will give radiographic quality welds with excellent bead appearance and is suitable for single and multiple pass welding. 80S-Ni2 is used for welding of fine grain structural steels if low temperature impact values are required. For service temperatures down to -76ºF (-60ºC).
