Inconel Bolt Corrosion Resistance
Inconel Bolt Corrosion Resistance
Inconel threaded rod, like Inconel 600, 601,625,686,718 & 725 threaded rods, are a nickel-chromium-molybdenum alloy used for its high strength at elevated temperatures and good corrosion resistance. Because of its high thermal stability it can be used in service temperatures ranging from cryogenic to 2200°F (982°C). The high alloy content in Inconel threaded rod, enables it to withstand a wide variety of severe corrosive environments. In mild environments such as the atmosphere, sea water, neutral salts, and alkaline media there is almost no attack to Inconel threaded rod. In more severe corrosive environments the combination of nickel and chromium provides resistance to oxidizing chemicals, whereas the high nickel and molybdenum contents supply resistance to nonoxidizing environments.

Because Inconel threaded rod offer a good balance of corrosion resistance, temperature stability, toughness and strength they are often a material of choice for chemical processing, aerospace, marine, electronics and oil & gas. 

  • High temperature stability up to 2200°F
Common Inconel Threaded Rod Grades
Inconel 600 Threaded Rod
A nickel-chromium alloy with good carburization and oxidation resistance through 2000°F. The alloy has long been used in the heat treating industry and Inconel 600 has useful resistance to dry Cl2 and HCl gases at moderately elevated temperatures.

Inconel 601 Threaded Rod
Inconel 601 is highly resistant to oxidation through 2200°F even under severe thermal cycling. The alloy has good high temperature strength, and retains its ductility after long service exposure. Inconel 601 alloy has good hot corrosion resistance under oxidizing conditions

Inconel 625 Threaded Rod
Inconel 625 is the workhorse of Inconel being one of the most common grades for fasteners. It exhibits high creep-rupture strength and is oxidation resistant to 1800°F (982°C). Inconel 625 has excellent resistance to hot seawater, scrubber environments and reducing acids and this alloy resists a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion.

Inconel 686 Threaded Rod
An alloy designed for outstanding corrosion resistance in a wide range of severe environments. The alloy is used in the most severe environments encountered in chemical processing, pollution control, pulp and paper production, and treatment of industrial and municipal waste.

Inconel 718 Threaded Rod
Inconel 718 is the most common grade of the hardenable Inconels. This precipitation-hardened nickel-chromium alloy combines outstanding corrosion resistance and high strength at elevated temperatures. The alloy is a about 2x as strong as Inconel 625 having excellent creep-rupture strength at temperatures to 1300°F (700°C). Inconel 718 is often used in gas turbines, rocket motors, spacecraft, nuclear reactors, pumps, and tooling.


Inconel 725 Threaded Rod
A nickel-chromium-molybdenum-niobium age-hardenable alloy that has essentially the same corrosion resistance as Inconel 625, but with a strength of that is twice that of annealed Inconel 625. The strength of this alloy is developed by heat treatment to achieve high ductility and toughness. The alloy is resistant to hydrogen embrittlement and stress-corrosion cracking as well.
