Inconel 718 Bolts and Forging

AMEC approved Manufacturer and supplier of EN/DIN 2.4668 nut bolt and UNS N07718 Fasteners in India

Established as having excellent weldability in terms of being joint, Inconel 718 hex bolt is a Gamma double prime strengthened alloy. Which puts Inconel 718 in the category of high performance superalloys

Keeping in accordance with the typical properties of superalloys, the Alloy 718 studs bears witness to many of their characteristics. Important among them are its excellent mechanical strength as well as resistance to thermal creep deformation. In nickel based alloys that belong to the Gamma double prime category such as the Alloy 718 forging, addition of niobium or vanadium in the alloy is what is used to strengthen the alloy.

Additionally, the Inconel 718 stud bolts demonstrate good surface stability along with having superior resistance to corrosion and oxidation as well. Which is why these ASTM B637 UNS N07718 bolts are ideally selected to be used for the building of turbine engines. Since turbine engines run on basic thermodynamic principles, the efficiency of turbine engines has been increased with an increase in turbine inlet temperatures.

This increase in temperatures is what prompts many of our clients to use superalloy Inconel 718 forged rings. Since Inconel, has nickel as its primary alloyant, using the Inconel 718 fasteners at hoisted temperature shows no negative effect on either the application or on the equipment being used. Aside from being capable of withstanding very high temperature, these Alloy 718 nuts are useful in high pressured environments too.

718 Inconel Hex Head Bolts Welding

Known for having remarkable weldability, Inconel 718 bolts can be welded in either the annealed or matured condition. This is particularly helpful for applications using weld studs. Because of its age solidifying measure, Inconel 718 bolts can be welded without solidifying or breaking.

 

Nickel 718 Fasteners advantages
  • Minimize galling with proper coating and plating.
  • Often manufactured with MacLean-Fogg Lockthread
  • Minimize oxidation and corrosion at high temperature.
  • Specialty alloys to withstand up to 800 degrees Celsius.
  • Metric and Inch sizes available

Alloy 718 bolts forging processes

A single piece of billet is heated to the desired temperature less than the melting point of the alloy and then forged. The temperature is just below 1260 degrees Celsius and depends on the size and shape of the bolt that has to be produced. It is then forged by one piece of metallic component against another piece of metallic component both which have the grooves for the shape and size of the bolt. The bolt is then threaded by machining if it is a threaded bolt. Plain bolts are also used in structural applications. The bolts are used in high temperature, high corrosion prone applications such as the aerospace components and in the oilfield accessories.
