It is 22% chromium duplex stainless steel.

The nut has internal threads so that it can be tightened easily on the bolt. The size of the nut is smaller than that of the bolt. The nuts experience compression forces. It is compressive stress that leads to its failures. There are different types of nuts: Hex Nut, Nylon Insert Lock Nut, Jam Nut, Nylon Insert Jam Lock Nut, Square Nut, Cap Nut, Acorn Nut, T-Nut, Cape Nut, Castle Nut, Wingnut, Flange Nut, Slotted Nut, Coupling nut, etc. most common type of nut found today is a hexagonal nut.

Supler Duplex Steel UNS S32760 stud bolt has a higher yield strength and lower ductility than the austenitic steels so fabricators may find that higher forming forces, increased radius of bending, and increased allowance for spring-back are necessary.

Inconel 600 Bolts can also be easily formed, machined and welded. The minimum tensile strength of fasteners can reach 825MPa, and the minimum yield strength can reach 620MPa. The strongest are cold-worked round fasteners.

C22 nickel alloy fasteners offer better overall corrosion resistance than its sister alloy Hastelloy C-276, and more specifically, it offers better protection when used in certain saturated wet chlorine environments. Additionally, its high chromium content provides C22 fasteners with better resistance to oxidative media than C276. This makes it excellent resistance to chloride-induced pitting, although in most cases C-276 fasteners are a more cost-effective option due to their availability, especially in sizes smaller than 1/ 2″ case.
