MIDALLOY ER80S-D2 Bare WELDING WIRE CLASSIFICATION ? AWS 5.28 Class ER80S-D2 / ASME SFA 5.28 Class ER80S-D2 DESCRIPTION ? MIDALLOY ER80S-D2 welding wire is a bare wire, used for GMAW and GTAW welding. APPLICATION ? MIDALLOY ER80S-D2 welding wire is designed for the gas metal arc welding and gas tungsten arc welding when moderately high strength and good sub-zero toughness is needed in the PWHT condition. ? Preheating and interpass temperatures of not less than 300°F must be used during welding.
