What is a super duplex bolt?
Super duplex bolts are fasteners whose shank consists of threads emerging from below their head. They have higher mechanical strength and better creep resistance even at higher temperatures.

Do super duplex stainless steel fasteners corrode?
Unlike traditional stainless steel alloys, they are highly alloyed. Thus these fasteners have a higher PREN value (pitting resistance equivalent number) i.e. – 38 – 45. They are better at resisting corrosion compared to duplex alloys and work well in stronger acid and base environments.

Super duplex nuts and bolts and disadvantages
The fact that super duplex grades are highly alloyed and their mechanical and corrosion resistance properties of these alloys is ranges from excellent to good. They have one drawback. There may be a development of intermetallic phases or a drastic reduction of impact resistance if they are improperly processed.

Application of super duplex washers
Components made from super duplex alloys were specifically designed to cater for the demands of the oil and gas industry. The deposition of hydrogen or sulfur on traditional stainless steel pipes would cause them to break down by stress-related corrosion cracking. Since the PREN of super duplex fasteners is higher, they deliver excellent performance in the oil and gas sector.

Super duplex carriage Bolt vs U Bolt
A carriage Bolt is similar in appearance to a U Bolt. However, they are shorter in length and are used to fasten two materials together without a nut. These are preferred in assemblies that require very small and/or unobtrusive fastening. A super duplex U Bolt, on the other hand, is used in structural assemblies. They have higher tensile strength and can form both temporary & permanent attachments.
