■ Mechanical Properties & Yield Strength
Inconel 718 Fasteners achieve their extreme strength through precipitation hardening. Below are the mechanical properties required for demanding EPC and structural applications:
| Tensile Strength (Min) | Yield Strength 0.2% Offset (Min) | Elongation (%) | Hardness (HRC) |
|---|---|---|---|
| 185 ksi (1275 MPa) | 150 ksi (1034 MPa) | 12% Min | 36 - 44 HRC |
■ Aerospace & High-Temperature Applications
Inconel 718 is highly versatile, retaining its mechanical properties from cryogenic temperatures up to 1300°F (704°C).
- Aerospace & Aviation: Jet engine components, gas turbine blades, and structural aerospace fasteners.
- Oil & Gas / EPC: Down-hole shafting, high-pressure wellhead parts, and sour gas (H2S) environment joints.
- Nuclear Engineering: Reactor internals requiring high strength and resistance to neutron degradation.
- Cryogenic Storage: Liquid natural gas (LNG) tanks and cryogenic transfer lines.
■ Quality Assurance & MTC Downloads
As a primary manufacturer based in Mumbai, our quality control goes beyond standard chemical analysis. We conduct rigorous first-hand testing on all Inconel 718 Fasteners to ensure they meet the stringent safety requirements of EPC contractors and aerospace engineers.
- Ultrasonic Testing (UT): Internal flaw detection performed on raw billets prior to machining.
- Destructive Testing: In-house tensile, yield, and shear testing to verify precipitation hardening efficacy.
- PMI (Positive Material Identification): 100% optical emission spectroscopy scanning prior to dispatch.
