Ed Stainless supplies AWS Class ER308/308H MIG and TIG filler welding wire and rod, designed in Houston, USA for high-temperature and structural applications. ER308 is great for general welding of austenitic stainless steels, while ER308H has a higher carbon content to improve creep strength in hot environments. These filler metals meet strict AWS standards and produce strong welds with good ductility and corrosion resistance. Used in sectors like oil and gas, power generation, and petrochemical processing, Ed Stainless provides high-quality welding materials for critical applications.
ER308/308H fillers contain 19-21% chromium and 9-11% nickel, with a carbon content around 0.04-0.10% in ER308H for better high-temperature strength. The standard ER308 version has ≤0.08% carbon. These fillers deliver tensile strength of ~80 ksi, yield strength ≥55 ksi, and elongation of ≥30%. The increased carbon in 308H provides better creep resistance, making it suitable for high-temperature service. Both versions offer stable arc performance and good corrosion resistance, making them reliable options for structural and thermal applications involving stainless steel grades like 304 and 304H.

ER308 and ER308H fillers are commonly used for welding 304/304H stainless steels in high-temperature pressure vessels, boilers, reactors, and heat exchangers. The 308H variant is particularly suited for elevated temperature applications that need improved creep strength, such as in power plants and refineries. Standard ER308 is great for structural and general-purpose welding of stainless steels in tanks, frames, piping, and fabrications exposed to moderate heat and corrosion. These filler wires and rods work well for both TIG and MIG welding. Ed Stainless ensures reliable products, AWS compliance, and tailored support for industrial and commercial welding operations.
