Harshita Stainless, a reputable manufacturer and supplier based in Delhi, India, specializes in top-notch 309LMo MIG and TIG Filler Welding Wire and Rod, perfect for high-performance stainless steel welding. These filler materials are crafted specifically for welding dissimilar steels and overlay applications that demand exceptional corrosion resistance in tough environments. With a carefully controlled chemistry that includes molybdenum, they offer improved resistance to pitting and crevice corrosion. Harshita Stainless guarantees consistent mechanical and metallurgical properties in every batch, ensuring clean, stable arc performance and outstanding weld quality. These wires and rods are perfect for critical applications in the chemical, offshore, and marine sectors.
309LMo MIG and TIG Filler Wire and Rod are low-carbon austenitic stainless fillers that contain about 23% Chromium, 13% Nickel, and 2.5–3% Molybdenum. The low carbon content (<0.03%) boosts resistance to intergranular corrosion, while molybdenum enhances resistance to pitting and crevice corrosion. Typical mechanical properties include a tensile strength of 600–650 MPa, a yield strength of around 400 MPa, and an elongation of 30%. These fillers showcase smooth arc characteristics, minimal spatter (MIG), and excellent weld pool control (TIG), providing high strength and remarkable corrosion resistance in both single- and multi-pass applications.
