These bolts are made from high-performance Super Duplex Stainless Steel, usually in grades S32750 or S32760, which are rich in chromium, molybdenum, and nitrogen. This unique blend gives them impressive tensile and yield strength, excellent toughness, and outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in environments filled with chlorides and aggressive chemicals. Such characteristics make them perfect for structural and mechanical fastening in critical applications where reliability is a must.

Super Duplex Steel Bolts find their place in oil and gas platforms, chemical and petrochemical plants, and marine systems, where they secure flanges, pressure vessels, pipelines, and heavy machinery. They excel in situations with high pressure, high temperatures, and corrosive conditions, where standard fasteners would simply fail. Thanks to their superior mechanical strength, corrosion resistance, and long-lasting durability, Super Duplex Steel Bolts are the go-to choice for demanding, high-performance, and safety-critical industrial applications.
