With a firm dedication to reliability, performance, and customer satisfaction, Al Vishwas Nickel Alloys continues to be a trusted source for long-lasting and affordable Duplex Steel fastening products.
Duplex Steel Bolts are made from stainless steel alloys that generally include roughly 22–25% chromium, 5–7% nickel, 3–4% molybdenum, and a regulated quantity of nitrogen. This distinctive combination produces a balanced duplex microstructure composed of ferrite and austenite, giving the bolts outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. From a mechanical standpoint, Duplex Steel offers high tensile and yield strength—far exceeding that of many conventional stainless steels—together with remarkable fatigue resistance and toughness. Thanks to these properties, Duplex Steel Bolts can operate dependably under high stress, high pressure, and varying temperature conditions.
