Product Overview
Inconel 625 is a solid-solution strengthened nickel alloy designed to perform in environments where conventional stainless steel components fail. The alloy offers remarkable resistance to chloride stress corrosion cracking, pitting, crevice corrosion, seawater attack, oxidation, and carburization. Washers manufactured from this alloy distribute fastening loads evenly while preventing damage to bolted joints and maintaining secure assemblies during thermal expansion and vibration.
These washers are commonly available as flat washers, spring washers, lock washers, square washers, plain washers, heavy-duty washers, shim washers, and custom-machined washers. Standard sizes are manufactured from M3 to M100 and larger custom dimensions, while imperial sizes are also available according to project requirements.
Material Composition and Chemical Properties
The superior performance of Inconel 625 is achieved through its carefully balanced chemical composition.
Typical composition includes:
- Nickel (Ni): Minimum 58%
- Chromium (Cr): 20–23%
- Molybdenum (Mo): 8–10%
- Niobium + Tantalum (Nb + Ta): 3.15–4.15%
- Iron (Fe): Maximum 5%
- Cobalt (Co): Maximum 1%
- Manganese (Mn): Maximum 0.50%
- Silicon (Si): Maximum 0.50%
- Carbon (C): Maximum 0.10%
- Titanium (Ti): Maximum 0.40%
- Aluminum (Al): Maximum 0.40%
- Phosphorus (P): Maximum 0.015%
- Sulfur (S): Maximum 0.015%
This balanced chemistry enables outstanding corrosion resistance in acidic, alkaline, oxidizing, and reducing environments while maintaining excellent weldability and fabrication characteristics.
Mechanical Properties and Pressure Resistance
One of the major reasons industries specify Inconel 625 washers is their excellent mechanical strength over a wide temperature range. Even after prolonged exposure to elevated temperatures, the alloy retains impressive tensile strength and fatigue resistance.
