Product Description
Inconel 718 Nickel Alloy Round Bar – UNS N07718
ECER supplies premium Inconel 718 (UNS N07718 / W.Nr. 2.4668) nickel-chromium alloy round bars engineered for extreme high-temperature and corrosive environments. As a precipitation-hardenable nickel-based superalloy, Inconel 718 delivers exceptional tensile strength, creep resistance, and fatigue life up to 704°C (1300°F), making it the material of choice for critical aerospace and energy applications.
Key Features
- Superior High-Temperature Strength – Maintains mechanical integrity at elevated temperatures, resisting creep and stress rupture under sustained loads
- Excellent Corrosion Resistance – Outstanding resistance to pitting, crevice corrosion, and chloride stress-corrosion cracking in sour gas environments
- Precipitation Hardenable – Achieves maximum strength through solution annealing followed by aging heat treatment, with minimal distortion
- Weldability – Excellent resistance to post-weld strain-age cracking, ideal for complex fabricated assemblies
- Cryogenic Performance – Retains ductility and toughness at cryogenic temperatures down to -253°C (-423°F)
Available Conditions
| Condition | Description | Typical Hardness |
|---|---|---|
| Solution Annealed | Heated to 927-1010°C, air cooled or faster. Optimal for subsequent machining and forming. | 240-300 HBW |
| Aged (Precipitation Hardened) | Solution annealed + 718°C/8h furnace cool to 621°C + 621°C/8h air cool. Maximum strength condition per AMS 5662. | 331-400 HBW |
| Hot Rolled | Rolled above recrystallization temperature. Suitable for general structural applications. | As rolled |
| Cold Drawn | Drawn at room temperature for enhanced surface finish and dimensional tolerance (h9/h10). | Work hardened |
