ER80S-B8
Alloy Type: A5.28, LOW-ALLOY STEEL Filler Metals for Gas Shielded Arc Welding
ER80S-B8 is used for joining 9Cr-1Mo air hardening steels for elevated temperature creep service, and with corrosion resistance from steam, hot hydrogen gas, and high sulfur crude oils. These include steels such as A335 Grade F9, A336 Grade F9, A217 C12 (Cast). And A199, A220 and A213 grade T9, used primarily in the petrochemical and refinery industries. A preheat and interpass temperature of not less than 400⁰ should be maintained during welding.
