Vinit Stainless, a well-respected manufacturer and supplier located in Chennai, India, specializes in high-quality AWS Class ER308/308H Submerged Arc Welding (SAW) Wires and Matching Fluxes tailored for critical stainless steel welding tasks. These austenitic stainless filler metals are crafted for joining 304, 304H, 308, and 308H grades, ensuring top-notch weld strength, corrosion resistance, and creep resistance even at high temperatures. Vinit’s SAW wires, paired with low-hydrogen, slag-forming fluxes, deliver outstanding arc stability, a smooth bead appearance, and minimal weld defects. These solutions are perfect for boiler fabrication, pressure vessels, petrochemical plants, and nuclear piping systems that demand metallurgical reliability.
The AWS Class ER308/308H SAW wire features around 19–21% chromium, 9–11% nickel, and a carbon content of up to 0.08% (for 308H), making it ideal for high-temperature applications. The fluxes that accompany these wires facilitate excellent slag removal and reduce spatter. Mechanical properties include a tensile strength of at least 550 MPa, yield strength of at least 350 MPa, and elongation of at least 30%. The stabilized microstructure guarantees remarkable ductility, creep resistance, and corrosion performance, even in thermally cycled environments. This combination is perfect for applications involving intermittent heating up to 850°C.
