Super-duplex developed later to meet specific demands of the oil& gas as well as those of the chemical industries. This grade of stainless steel is also known as or Hyper duplex grades by Super Duplex Fasteners Manufacturer. Super duplex stainless steel  grades are available in a variety of shapes, configurations & specifications like fasteners, bard, rods, etc. An advantage of super duplex stainless steel is its good ductility and weldability.

Labelled as Super duplex grade of stainless steels, these Super Duplex 2507 Bolts have a similar microstructure as duplex grade stainless steels. The term duplex indicates that this alloy has a mixed austenite and ferrite microstructure in an equal proportion. This two-phase microstructure in the 2507 Nuts guarantees higher resistance to stress corrosion cracking and pitting when compared with conventional stainless steel grades like the 300 series or nickel-based alloys etc. 2507 Stainless Steel Fixings are especially useful in industries like offshore oil and gas and applications in wells in the presence of either naturally high brine levels or brine has been injected to enhance recovery.
