Duplex Steel Threaded Fittings are high-strength forged fittings designed for
excellent corrosion
resistance, superior mechanical properties, and outstanding resistance to stress
corrosion cracking.
With a balanced austenitic–ferritic microstructure, these fittings perform reliably
in high-pressure and
corrosive service environments.
Duplex Steel Threaded Fittings are manufactured in precision-forged form with
threaded connections and
are widely used in oil & gas, offshore platforms, chemical processing plants, marine
systems, power
generation, and industrial piping applications where durability and leak-free
performance are essential.
Duplex Steel Threaded Fittings are available in standard duplex stainless steel
grades to suit demanding
operating conditions. The most commonly supplied grades include
Duplex S31803 (UNS S31803) and
Duplex S32205 (UNS S32205), known for their excellent resistance to
pitting and crevice
corrosion, high yield strength, and good weldability.
