Njabulo Stainless, located in Cape Town, South Africa, is a reputable manufacturer and supplier of Alloy 309LMo SAW and Flux. This combination is specifically designed for submerged arc welding (SAW), ensuring that you get high-quality, durable welds for austenitic stainless steels, even in high-temperature and corrosive settings. With its remarkable weld penetration, minimal spatter, and smooth bead formation, Alloy 309LMo SAW and Flux create strong, crack-resistant joints. It’s widely utilized in sectors like chemical, petrochemical, power generation, and industrial fabrication, where Njabulo Stainless provides welding consumables that blend mechanical strength, corrosion resistance, and high-temperature stability for critical welding tasks.
Alloy 309LMo SAW and Flux is made up of iron, combined with 23–25% chromium, 13–15% nickel, and 1–2% molybdenum, while keeping the carbon content low (≤0.03%) to reduce carbide precipitation. The flux guarantees excellent arc stability, a smooth weld bead, and consistent deposition. Weld deposits can reach tensile strengths of up to 650 MPa, showcasing impressive ductility, toughness, and thermal stability. The synergy between the alloy and flux ensures corrosion resistance, high-temperature strength, and crack resistance, making it perfect for joining austenitic stainless steels in challenging industrial and high-temperature conditions.
