Duplex Steel Fasteners find extensive use across various industries, including oil and gas, petrochemicals, marine, chemical processing, and power generation. They are particularly suited for offshore platforms, pipelines, pressure vessels, and desalination plants, where exposure to chloride-rich environments is a given. In marine engineering, they ensure secure fastening for ships, pumps, and heat exchangers that come into contact with seawater. With their blend of strength, durability, and corrosion resistance, Duplex Steel Fasteners are the top choice for heavy-duty applications in extremely challenging service conditions.
These fasteners are primarily made up of chromium (about 22–25%), nickel (4–7%), and molybdenum (up to 4%), with nitrogen included to boost strength and corrosion resistance. This well-balanced composition gives them a unique dual-phase microstructure, making them twice as strong as standard stainless steels. On the mechanical side, these fasteners show impressive tensile strength ranging from 620 to 880 MPa, along with high yield strength and excellent toughness, even in freezing temperatures. Their outstanding mechanical profile guarantees dependable performance in both high-stress and corrosive settings.
