Alloy ER 308H is used for welding of unstabilized stainless steels such as Types 301, 302, 304, 304H, 305, 308 and 308H. This filler metal is also used for general-purpose applications where corrosion conditions are moderate. The classification is the same as alloy ER 308, except that the allowable carbon content has been restricted to the higher portion of the 308 range. Carbon content in the range of 0.04-0.08 provides higher strength at elevated temperatures.
