Andre Stainless provides AWS Class ER308 and ER308L SAW wire and associated flux combinations designed for submerged arc welding of low-carbon stainless steels. Servicing Singapore and Pulau Ujong‘s fabricating industry, Andre Stainless provides high availability and product reliability for stainless work requiring minimum sensitization risk. Optimized for high-productivity use in ship construction, petrochemical equipment fabricating, and stainless structure fabrication, the system is supported by Andre Stainless’s timely technical assistance. With the ER308L type, welders receive superior resistance to intergranular corrosion, while ER308 provides ease of feeding and weld integrity—supported by Andre Stainless‘s reliable technical support.
Both wires have 18–20% chromium and 9–11% nickel. ER308L has carbon <0.04% to minimize carbide precipitation; ER308 is the same but a bit higher. Tensile strength is generally >560 MPa, with elongation ~30%. The flux system assists in achieving deep weld penetration, stable slag, and clean bead profiles. This blend produces corrosion- and crack-resistant welds with smooth morphology. ER308L is particularly well-suited for applications that require long-term corrosion resistance in thermal cycles, and both are readily converted for flat and horizontal SAW operations.

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.
Applicable for welding Type 304/304L stainless steel parts with submerged arc processes, the system is commonly utilized in process vessel fabrication, tank fabrication, heat exchanger fabrication, and piping system fabrication. ER308L is used in food, dairy, and pharmaceutical industries where intergranular corrosion is a problem. ER308 has wider applications in general stainless structural constructions. Uses include chemical plants, heating ventilation air conditioning systems, marine equipment, and refinery machinery. The SAW equipment accommodates large welded seams with high deposition rates, making it ideal for industrial stainless steel welding operations.
