Aditya Stainless, a reputable manufacturer and supplier located in Kolkata, India, specializes in high-quality AWS Class ER308/308L Submerged Arc Welding (SAW) Wire and Flux. These products are specifically designed for welding austenitic stainless steels in tough industrial settings. This filler metal is perfect for joining 18Cr-8Ni stainless steels like 304 and 304L, especially when a low carbon content is necessary to avoid intergranular corrosion. When paired with the right flux, it ensures excellent slag removal, stable arcs, and a smooth bead finish. Commonly used in pressure vessels, structural components, and piping systems, ER308/308L SAW wire guarantees strong, corrosion-resistant welds with minimal contamination.
ER308/308L SAW wire is composed of 19.5–22% chromium, 9–11% nickel, and a maximum carbon content of 0.03% (for the “L” version). This blend provides outstanding corrosion resistance and weldability. When used alongside compatible SAW flux, the typical mechanical properties of the deposited weld metal include a tensile strength of at least 75,000 psi (520 MPa), yield strength of at least 55,000 psi (380 MPa), and an elongation of about 30%. The low carbon content helps reduce the risk of carbide precipitation, maintaining corrosion resistance even in high-temperature or corrosive environments. Welds remain ductile, robust, and stable under both mechanical and thermal stresses.
