Product Overview
Inconel 625 Fasteners are manufactured from a solid-solution strengthened nickel alloy known for its remarkable resistance to oxidation, pitting, crevice corrosion, chloride attack, and stress corrosion cracking. Unlike precipitation-hardened alloys, Inconel 625 derives its strength primarily from molybdenum and niobium, providing superior mechanical performance without extensive heat treatment.
The alloy maintains excellent structural integrity under extreme thermal cycling, making it suitable for equipment exposed to temperatures ranging from cryogenic conditions up to approximately 980°C. Because of these characteristics, industries continue to prefer Inconel 625 Fasteners where reliability cannot be compromised.
Material Composition
The outstanding performance of Inconel 625 Fasteners comes from its carefully balanced chemical composition.
Typical chemical composition includes:
| Element | Percentage |
|---|---|
| Nickel | 58% Minimum |
| Chromium | 20–23% |
| Molybdenum | 8–10% |
| Niobium + Tantalum | 3.15–4.15% |
| Iron | Maximum 5% |
| Cobalt | Maximum 1% |
| Aluminum | Maximum 0.40% |
| Titanium | Maximum 0.40% |
| Carbon | Maximum 0.10% |
| Manganese | Maximum 0.50% |
| Silicon | Maximum 0.50% |
This alloy chemistry provides remarkable resistance against oxidizing and reducing acids, seawater, chlorides, and aggressive industrial chemicals.
Mechanical Properties
The superior mechanical characteristics make Inconel 625 Fasteners suitable for highly demanding applications.
Typical mechanical properties include:
| Property | Value |
|---|---|
| Tensile Strength | 827 MPa Minimum |
| Yield Strength | 414 MPa Minimum |
| Elongation | 30% Minimum |
| Hardness | Approximately 220 HB |
| Density | 8.44 g/cm³ |
| Melting Range | 1290–1350°C |
These properties enable the fasteners to maintain structural integrity even under continuous heavy loads, cyclic stresses, and elevated temperatures.
