From the heart of Manama, Bahrain, Niazi Stainless stands as a trusted partner for industry, providing precision-engineered welding solutions. We take pride in supplying the high-performance AWS Class ER320LR MIG and TIG filler rod welding wire, a product specifically formulated for demanding environments. This wire is designed for professionals who require unwavering reliability when joining specialized alloys, ensuring strong, durable welds that stand the test of time in critical applications.
The ER320LR wire is distinguished by its balanced composition, which includes chromium, nickel, and molybdenum, topped with a low carbon content (hence the “LR” for Low Residual). This specific chemistry is key to its performance, delivering exceptional resistance to cracking while promoting a smooth, stable arc during both MIG and TIG processes. The resulting welds exhibit impressive tensile strength and excellent ductility, meeting the rigorous mechanical standards required for challenging fabrication and repair work.
