Bolts of Inconel 718 are used for landing nipples, polished hole sockets in sour gas service, and side pockets or hangers. In addition, it is used in high-strength machines or tools in marine applications.

Alloy 718 fasteners are a major hardware element almost everywhere, whether it’s home appliances, machinery, automobiles, buildings, infrastructure, or any other item that needs to be assembled, there will definitely be fasteners to hold them all together.

Hastelloy C2000 fasteners combine the excellent resistance to oxidizing media of C276 with excellent resistance to non-oxidizing environments, making it a unique alloy for protecting chemical process equipment under a variety of conditions, including fluids contaminated with iron ions . It is designed to provide greater versatility than other Hastelloy alloys. This is achieved by increasing the content of chromium and molybdenum and adding a small but effective amount of copper (1.6%). The addition of copper increases the temperature capability of C2000 fasteners in sulfuric, hydrofluoric, and dilute hydrochloric acids.

Hex bolts are used to fasten two or more parts together to form an assembly either because it cannot be manufactured as a single part or to allow for maintenance and repair disassembly. By definition “A Bolt is a headed and externally threaded mechanical device designed for insertion through holes in assembled parts to mate with a nut and is normally intended to be tightened or released by turning that nut.” When used with a preformed internally threaded (tapped) hole, the hex bolt’s head is turned to tighten, which technically makes it a screw (see our Tech Data section for a discussion regarding the differences between bolts and screws). Hex bolts are also known as: hex head bolts, cap screws, hex cap screws, hex head cap screws, machine bolts, hex machine bolts, hex head machine bolts and, if fully threaded, tap bolts, hex tap bolts and hex head tap bolts. A hex bolt is often differentiated from a hex cap screw by its underhead bearing surface: if it has a circular boss, called a washer face, it’s a hex cap screw¡ªif it doesn’t then it’s a hex bolt.

Its high nickel content, a minimum of Ni 72%, combined with its chromium content, provides users of Nickel Alloy 600 a number of benefits such as good oxidation resistance at high temperatures and corrosion resistance to both organic and inorganic compounds.

It also exhibits extremely high tensile, yield and creep rupture properties at elevated temperatures. It is suitable for long-term use from low temperatures to 1200¡ãF. One of the defining features of the composition of B637 UNS N07718 is the addition of niobium to allow age hardening, which facilitates welding and annealing without unforced hardening during heating and cooling.

Inconel 625 bolts can be used in a variety of corrosive environments due to their ability to prevent stress corrosion, crevice corrosion and pitting corrosion. In mild applications such as atmospheric, fresh or salt water, neutral salts and alkaline media are almost completely tolerated. In more severe cases, nickel and chromium content provides resistance to oxidizing chemicals. Inconel 625 bolts are also resistant to non-oxidizing environments.

Its corrosion resistance also finds other uses in the chemical, food, pharmaceutical and plastics industries. Alloy 20 resists pitting and chloride corrosion, and its copper content protects it from sulfuric acid. Alloy 20 is not SS, but a nickel alloy (ASTM).

Similar to Inconel grades, Incoloy grade alloys have nickel and chromium as the main base elements. The only difference between these two alloy classes is their chemical composition. Inconel alloys contain almost more than 50% nickel, while Incoloy alloys are not only less than 50% nickel, but the alloys also contain iron. Known as a heat-resistant alloy, Inconel 825 has excellent properties. The most interesting properties of Incoloy 825 fasteners are their high creep resistance and high mechanical strength despite prolonged exposure to heat.
