Lecong Stainless stands out as a top manufacturer and supplier based in Da Nang, Vietnam, specializing in high-quality AWS Class ER308/308H SAW and Flux wires tailored for submerged arc welding. These filler wires are a go-to choice for welding 18Cr-8Ni austenitic stainless steels, especially Grades 304 and 304H, delivering outstanding corrosion resistance, impressive high-temperature strength, and smooth weld deposits. With a focus on consistent chemistry, controlled ferrite levels, and excellent arc stability, Lecong Stainless guarantees dependable performance across critical sectors like chemical processing, petrochemical, power generation, and marine engineering.
The AWS Class ER308/308H SAW and Flux wires contain 19–21% chromium and 9–11% nickel, with carefully managed carbon levels—ER308 features low carbon to reduce carbide precipitation, while ER308H has a higher carbon content for improved creep strength at elevated temperatures. These filler wires boast a tensile strength of about 550 MPa, a yield strength of around 350 MPa, and an elongation of 35% or more. This blend of properties ensures exceptional corrosion resistance, oxidation resistance, and mechanical stability in high-temperature environments.
