Later, a super-duplex was made to meet the needs of both the oil and gas and chemical industries. By another name this type of stainless steel is called Hyper Duplex type by the company that makes Super Duplex Fasteners. Different types of super duplex stainless steel are in different shapes, configurations, fasteners, bars, rods, etc. you can click the websites to contact us

Super Duplex Stainless Steel Fasteners Specifications
The word "duplex" means that this metal has an equal amount of austenite and ferrite in its microstructure. This two-phase microstructure is made of 300 series metals, nickel-based alloys, etc., found in 2507 nuts. It guarantees a higher resistance to stress corrosion cracking and pitting than conventional identical grades of stainless steel. Fixtures made of 2507 stainless steel are especially useful in the offshore oil and gas industry, where they have been used to improve recovery in wells with naturally high brine levels or where brine is present. The Super Duplex group of stainless steels shows that Super Duplex 2507 screws are made of a high alloy stainless steel with better performance. UNS S32760 Fg stud nuts and super duplex screws are much more resistant to acids, chlorinated compounds, and caustic solutions than 300-grade stainless steel. The high amount of chromium, nickel, and molybdenum in UNS S32760 stud nuts makes them much more substantial. For example, these three parts make UNS S32760 bolting more resistant to pitting and rust between the grains. Nitrogen is added to some super duplex grades of stainless steel to make them stronger. Nitrogen in the alloy of UNS S32750 bolts makes structural hardening happen, which improves the tensile and yield strength of SAFF 2507 bolts without changing the toughness of the stainless steel.
Oil and gas industry in the ocean Super Duplex fasteners are often used on offshore platforms, subsea equipment, and oil rigs where harsh temperatures and corrosive seawater are ordinary. They are very resistant to pitting, corrosion in pits, and breaking from stress corrosion. Industry of Chemicals and Petrochemicals In places like chemical processing plants and refineries, where harsh chemicals and high temperatures are frequent, Super Duplex fasteners are solid and don't rust. Marines and Building Ships Super duplex fasteners are used in shipbuilding and other marine settings because they can withstand seawater's corrosive effects and other marine conditions. Water Treatment Plants Where there is a lot of salt in the water, like in desalination plants, Nickel Alloy 200 Fasteners are very resistant to corrosion caused by chloride. Making electricity In power plants, Super Duplex screws are used, especially in places where fossil fuels are burned, and acidic generators are made. Strange results.
