Duplex fasteners are high-grade products made from duplex stainless steel and are among the best possible types in the combination of strength, corrosion resistance, and durability dimensions. Such fasteners are used in oil, gas, petrochemicals, the sea, and construction applications that need practical and reliable fastening means for critical applications. Duplex stainless steels are highly resistant to pitting, crevice corrosion, and cracking stress corrosion. Hence duplex steel fasteners are the most suitable for chemical, saltwater, and high-pressure applications along with all the benefits of various austenitic and ferritic stainless steels. All types of fasteners bolts, nuts, screws, washers, and studs are possible, making duplex steel fasteners versatile to cater to other industrial requirements. Duplex 2205 and Super Duplex 2507 are the grades that add extra strength and corrosion resistance to enable them to survive extreme conditions.
In fact, their strength is known to double or even triple that of regular stainless fasteners; hence these can carry heavier loads and can also deal with much more stringent environments. These can therefore freely be used for heavy-duty applications like pipelines, heat exchangers, and offshore platforms. Duplex steel fasteners are offered in various sizes, thread patterns, and finishes as per the specified requirement of the customer for the specific project. This makes them a reliable way to reduce the cost of critical operations in terms of maintenance. When strength, corrosion resistance, and reliability are indeed prioritized above all else, duplex steel fasteners shine in all conditions even in the toughest industrial ones.
