Heer Fittings is a prominent manufacturer and supplier of Duplex Steel UNS S32205 Buttweld Fittings in Delhi, India, offering high-strength, corrosion-resistant piping solutions to demanding industrial processes. The fittings—in elbows, tees, reducers, caps, and crosses—are produced in accordance with ASTM A815 and ASME B16.9 specifications. Duplex UNS S32205, or 2205 duplex stainless steel, has a balanced microstructure of about equal amounts of austenite and ferrite. This blend yields much greater strength and superior localized corrosion resistance than conventional austenitic stainless steels such as 316L.

UNS S32205 has about 22% chromium, 5–6.5% nickel, 3–3.5% molybdenum, and a controlled amount of nitrogen to provide improved mechanical and corrosion resistance properties. It has a tensile strength of 620–800 MPa, minimum yield strength of 450 MPa, and elongation of 25–30%. The duplex microstructure enables superior resistance to chloride stress corrosion cracking, crevice and pitting corrosion, even in aggressive chemical or marine environments. The alloy remains weldable and thermally stable, with wide application in pressure and fabrication applications.
