Product Overview and Material Composition
Inconel 625 is a solid-solution strengthened nickel alloy developed for outstanding corrosion resistance and high mechanical strength without requiring precipitation hardening. The alloy maintains its properties across a wide temperature range, making it suitable for both cryogenic and elevated-temperature applications.
Its typical chemical composition includes:
- Nickel (Ni): Balance
- Chromium (Cr): 20–23%
- Molybdenum (Mo): 8–10%
- Niobium + Tantalum (Nb + Ta): 3.15–4.15%
- Iron (Fe): Maximum 5%
- Minor additions of titanium, aluminum, manganese, silicon, carbon, phosphorus, and sulfur
This balanced composition provides excellent resistance against chloride-induced corrosion, oxidation, carburization, and chemical attack while delivering outstanding weldability and structural integrity.
Mechanical, Chemical, and Performance Properties
The superior performance of Inconel 625 comes from its carefully controlled alloy chemistry and outstanding mechanical characteristics. These bolts exhibit high tensile strength, remarkable fatigue resistance, and excellent creep strength under prolonged service conditions.
Typical mechanical properties include tensile strength exceeding 827 MPa, yield strength above 414 MPa, elongation around 30%, and excellent hardness suitable for heavy-duty fastening applications. The alloy also performs exceptionally well under cyclic loading, making it ideal for vibration-prone equipment.
From a corrosion perspective, Inconel 625 performs exceptionally in seawater, acidic environments, alkalis, chloride-containing solutions, and oxidizing atmospheres. It offers excellent resistance to pitting corrosion, crevice corrosion, intergranular attack, and stress corrosion cracking. The alloy also retains excellent oxidation resistance at temperatures approaching 980°C, making it suitable for continuous high-temperature operations.
International Standards and Specifications
Inconel 625 Bolts are manufactured according to internationally accepted quality standards to ensure compatibility with global engineering projects. Depending on application requirements, these fasteners are supplied in compliance with ASTM, ASME, DIN, EN, ISO, and JIS specifications.
Common specifications include ASTM B446, ASTM B564, ASME SB446, ASME SB564, and ASTM F468 for non-ferrous fasteners where applicable. The alloy is internationally recognized as UNS N06625 and Werkstoff Number 2.4856 under European standards. In Germany it is commonly referred to by its DIN/Werkstoff designation, while European industries identify it under EN standards. Japanese industries frequently specify the material according to JIS requirements, ensuring compatibility with regional manufacturing practices.
These international designations allow engineers and procurement teams to specify equivalent materials confidently across global projects.
