Super Duplex Steel Bolts crafted from UNS S32760, often referred to as Zeron 100, are specifically designed to thrive in harsh, corrosive environments where mechanical demands are high. These bolts are made from a high-alloy duplex stainless steel that features around 25% chromium, 7% nickel, and 3.6% molybdenum, along with some tungsten, copper, and nitrogen. This unique blend gives them remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. Thanks to their dual-phase microstructure, which includes both austenite and ferrite, S32760 bolts deliver exceptional strength and toughness, making them perfect for use in offshore oil and gas platforms, subsea systems, desalination plants, and chemical processing facilities.

When it comes to mechanical performance, S32760 bolts shine with a minimum tensile strength of 800 MPa and a yield strength of about 550 MPa, enabling them to handle heavy loads even in extreme conditions. They maintain their structural integrity under high pressure, elevated temperatures, and cyclic loading, while also standing up to erosion and corrosion from seawater, brine, and harsh industrial chemicals. This combination of strength, corrosion resistance, and reliability ensures they have a long service life and require less maintenance in critical applications.
Widely used in marine engineering, power generation, pulp and paper, and mining industries, Super Duplex S32760 bolts are the go-to choice for structural connections, flanged joints, pressure equipment, and heavy-duty assemblies that face tough environments. Their impressive performance in both oxidizing and reducing conditions makes them a dependable and cost-effective option for long-term use in the most challenging settings.
