Frequently Asked Questions (FAQ)

Inconel 718 is a high-strength, corrosion-resistant nickel-chromium alloy known for its excellent mechanical properties at high temperatures (up to 1300°F / 704°C) and resistance to oxidation and corrosion.

Inconel 718 bolts are known for Exceptional tensile, yield, and creep-rupture strength, Good fatigue resistance, Excellent weldability, Resistance to post-weld cracking, High resistance to corrosion and oxidation.

Inconel 718 bolts can maintain their strength and corrosion resistance in temperatures ranging from cryogenic (as low as -423°F / -253°C) to approximately 1300°F (704°C).

Yes, they are highly resistant to a wide range of corrosive environments including acids, seawater, and oxidizing environments.

Yes. Heat treatment typically includes solution annealing followed by age hardening to achieve desired mechanical properties.

Yes, manufacturers often offer custom bolt dimensions, threads, and surface treatments such as passivation or coatings depending on the application.

While stainless steel is corrosion-resistant, Inconel 718 offers superior performance in high-temperature and high-stress environments, with better fatigue and creep resistance.

Lead time varies based on size, quantity, and whether it's custom-made, but it typically ranges from a few days for stock items to several weeks for custom orders.

Common standards include ASTM B637, AMS 5662 / AMS 5663, ISO 9723 / ISO 9724 (for rods and bolts), NACE MR0175 (for sour service).

Typical mechanical properties include Tensile Strength: ≥ 135 ksi (930 MPa), Yield Strength: ≥ 70 ksi (480 MPa), Elongation: ~12–25%, Hardness: ~331–385 HB (varies by heat treatment).
