Harshita Stainless is one of the leading suppliers of AWS Class ER309/309L SAW and Flux from Delhi, India. Ideally suited for dissimilar metal welding and buffer layers, ER309/309L offers outstanding oxidation and heat scaling resistance. The low carbon “L“ grade minimizes the precipitation of carbides during welding to enhance intergranular corrosion resistance. Harshita‘s submerged arc welding consumables offer high strength, crack resistance, and cleanliness in bead formation. These products are suitable for the joining of stainless steel to carbon or low-alloy steels, and for overlaying surfaces which are exposed to high temperature and severe chemical conditions.
ER309/309L welding wire has a composition of 23–25% chromium and 12–14% nickel with a maximum of 0.03% carbon in the “L“ grade. This composition gives a strong, ductile weld deposit having good high-temperature strength and resistance to oxidation. Mechanical properties are tensile strength ≥80 ksi, yield strength ≥60 ksi, and elongation ≥30%. SAW flux provides stable arc control, smooth weld bead, and facile slag removal. ER309L has good hot crack resistance and is well suited for joining two dissimilar metals and as a buffer layer in high-temperature applications.
