Punit Fasteners, a leading supplier and manufacturer in Delhi, India, offers high-strength Duplex Steel Nuts suitable for harsh industrial settings. These nuts are made from duplex stainless steel, recognized for its dual-phase microstructure that combines austenite and ferrite, giving them exceptional strength and corrosion resistance. Duplex Steel Nuts work well in offshore platforms, chemical plants, desalination systems, and structural assemblies that need high tensile strength and protection against pitting and stress corrosion cracking. At Punit Fasteners, we ensure careful manufacturing and quality compliance to meet the demands of heavy-duty and high-performance applications.
Duplex Steel Nuts usually include 22–25% chromium, 5–7% nickel, 3–5% molybdenum, and nitrogen. This unique combination leads to high tensile strength (600–900 MPa), excellent yield strength, and superior corrosion resistance, especially against chlorides and sulfides. These nuts resist stress corrosion cracking and crevice corrosion very well. The duplex microstructure balances toughness and strength, with better fatigue performance than standard stainless steels. Their hardness and heat resistance make them suitable for high-pressure, high-temperature situations.
