The AWS Class ER308/308L SAW and flux wire is a specialized stainless steel welding consumable crafted for Submerged Arc Welding (SAW) of austenitic stainless steels like 304 and 304L. The “L” version features a low carbon content (≤ 0.03–0.04%) to help minimize carbide precipitation and intergranular corrosion. When paired with the right flux, it delivers high-deposition welds that boast excellent corrosion resistance, good toughness, and reliable mechanical properties. To enhance weld quality and performance, it’s crucial to manage heat input, control interpass temperatures, and prepare the base metal properly.
The typical composition of the weld metal includes carbon at ≤ 0.03–0.04%, chromium ranging from 19.5–22%, nickel between 9–11%, molybdenum up to 0.75%, manganese from 1–2.5%, and silicon at 0.3–0.65%. In terms of mechanical properties, you can expect a tensile strength of about 610 MPa, yield strength around 410 MPa, and elongation of 35–40%, which together create strong, durable, and corrosion-resistant welds that are perfect for tough environments.

After the production of AWS Class ER308/308L SAW and Flux, our quality control team conducts thorough checks using both destructive and non-destructive testing methods to ensure the highest standards of performance and reliability. We use advanced techniques to test the products weldability and corrosion resistance. We make sure that it meets the stringent requirements of our clients. Once verified we package the SAW and Flux with the utmost care to avoid any damage during shipping. Timely delivery is our priority and we make sure that the products reach the customer without delay. All relevant documentation is provided to the clients at the time of delivery for complete transparency and assurance.
ER308/308L SAW and flux are commonly used for welding stainless steel tanks, vessels, piping, pressure components, and structural fabrications in industries like chemical, food, beverage, and brewing. They’re also great for repair or overlay jobs where an austenitic stainless weld metal deposit is needed. Submerged Arc Welding is particularly effective because it ensures high deposition rates, deep penetration, and minimal spatter, making it a go-to choice for thick sections and large-scale fabrication projects.
