Inconel Nuts, Bolts, and Fasteners

At Atlanta Rod & Manufacturing, we manufacture Inconel 600 and Inconel 625 bolts, studs, and nuts to meet our customer’s specifications. With some of the most innovative products available in today’s marketplace, we work to ensure our clients receive only the best products made from the highest quality materials available.


Specifications of Inconel 600

A nickel-chromium-iron alloy, Inconel 600 is not hardened or strengthened by precipitation, but only by cold work. The specifications of Inconel 600 are listed below.

Cold worked rounds, as worked:

  • Under 1/2”, or 12.7 mm: Tensile strength, psi (MPa) 120,000 (820). Yield strength, psi (MPa): 90,000.
  • 1/2” to 1” (12.7 to 25.4mm): Tensile strength 110,000 (760). Yield strength 85,000 (585).
  • Over 1” to 2 1/2” (25.4 to 63.5 mm): Tensile strength 105,000 (725). Yield strength 80,000 (550).

Hot worked rounds, as worked:

  • 1/4” to 1/2” (6.4 to 12.7mm): Tensile strength 95,000 (655). Yield strength 45,000 (310).
  • Over 1/2” to 3” (12.7 to 76.2mm): Tensile strength 90,000 (620). Yield strength 40,000 (275)

Benefits of Inconel 600

Uniquely manufactured to resist both heat and corrosion, Inconel 600 combines superior strength with outstanding workability that won’t crack due to chloride ion stress corrosion. With its resistance to oxidizing conditions when faced with corrosive materials or high temperatures, Inconel 600 is known for its strength, durability, and resistance to corrosion. As a result, Inconel 600 stands up to harsh environmental conditions without need for repair or replacement, keeping structures safe while reducing cost.

Applications of Inconel 600

Customers within the chemical industry favor Inconel 600 for use in heating applications, bubble towers, condensers, and stills, among other uses. Often, it is used to process fatty acids and in manufacturing sodium sulfide. Professionals within the paper pulp industry have found Inconel 600 extremely useful in handling abietic acid. It is also used in evaporator tubes, flaking trays, and tube sheets.

Inconel 625 Bolts, Studs and Nuts

In addition to Inconel 600, Atlanta Rod manufactures Inconel 625 bolts, nuts, and studs. A nickel chromium alloy, Inconel 625 is known for its strength and resistance, even in high temperature environments. From aerospace to seawater environments, Inconel 625 fasteners have earned a reputation for superior performance and value.

Specifications of Inconel 625

The unique combination of elements in Inconel 625 and the effects of niobium and molybdenum make this alloy a solid choice, suitable for use in a number of industries. The nickel chromium matrix gives Inconel 625 superior strength and resistance to corrosion, carburization and oxidation. Its chemical composition percentages are as follows:

  • Ni: 58 percent
  • Cr: 20 to 23 percent
  • Fe: Maximum of 5 percent
  • Mo: 8 to 10 percent
  • Nb+Ta: 3.15 to 4.15 percent
  • C: Maximum of 0.10 percent
  • Si: Maximum of 0.50 percent
  • P: Maximum of 0.015 percent
  • S: Maximum of 0.015 percent
  • Al: Maximum of 0.40 percent
  • Ti: Maximum of 0.40 percent
  • Co: Maximum of 1 percent
  • Mg: Maximum of 0.50 percent

Benefits of Inconel 625

There are many benefits to Inconel 625 bolts, studs, and nuts, including:

  • Ability to meet custom specifications
  • High, uniform resistance to corrosive environments
  • Resistance to extreme temperatures
  • Resistance to carburization and oxidation
  • Superior creep, rupture, tensile, and thermal fatigue strength
  • Fatigue resistance
  • Chloride ion stress corrosion cracking resistance
  • And more

Applications of Inconel 625

There are four primary industries in which Inconel 625 is frequently used, including chemical processing, nuclear, aerospace, and seawater applications. Particularly due to its high corrosion fatigue strength, Inconel 625 is preferred in seawater environments and known for its high tensile strength and resistance to cracking from chloride ion stress corrosion.

In the aerospace industry, professionals prefer Inconel 625 because of its thermal fatigue strength and resistance to rupture. Inconel 625 is also used in chemical processing, thanks to its serious corrosion resistance regardless of pressure or temperature changes. These qualities make Inconel 625 an ideal fit for the nuclear industry where, like other trades, one non-functioning fastener may create an unsafe working environment.
