Incoloy 925 washers are high-performance, age-hardenable corrosion-resistant fasteners engineered to maintain secure joints and prevent leaks in aggressive chemical and high-pressure environments. As a premier manufacturer and supplier, Renine Metalloys provides these nickel-iron-chromium washers with added molybdenum, copper, and titanium to reliably hold clamping loads in oil, gas, offshore, and chemical processing units where sour service, chloride ions, and stress-corrosion cracking degrade standard fasteners.

Composition drives performance here. The alloy runs 60-70% nickel, 19-22% chromium, 5-7% iron, 2-3% cobalt, and 2-3% molybdenum, with titanium added for age-hardening strength that most nickel-iron-chromium alloys don't carry. That combination is what lets 925 washers hold up in high-pressure oil and gas wells where 825 grade would fall short on strength alone. Beyond standard 925, we also carry Inconel 600 washers and Incoloy 825 washers for applications with different pressure or temperature profiles.

Incoloy 925 Washers come in two primary types: flat washers and lock washers. Flat washers are used to spread the load of a fastener across a wider area than the fastener itself would otherwise occupy, while lock washers can be used to prevent screws or bolts from loosening due to vibration or thermal expansion. Both types are available in different sizes and configurations to meet the specific needs.
Incoloy 925 Washers
Alloy 925 Plain Washers can be used in virtually any application where metal components need to be held securely together with fasteners. The material’s superior heat resistance makes it ideal for use in areas subject to high temperatures, such as engines or exhaust systems. Its corrosion resistance makes it perfect for marine environments or other areas where corrosion could be an issue. Its strength makes it suitable for use in heavy machinery or equipment that must withstand significant loads or impacts without deforming or breaking apart. Different types of products are available, such as Weld Neck Raised Face Flanges, Spectacle Blind Flanges, etc.
Nickel Alloy UNS N09925 Washer is an extremely versatile material that has many uses in industrial applications due to its superior heat resistance, corrosion resistance and strength. Whether there is a need of flat washers for support purposes, lock washers for security purposes, or something else entirely.
What are Incoloy 925 Washers?
Incoloy 925 Washers are high-performance alloy washers made from a nickel-iron-chromium alloy with added molybdenum, copper, and titanium. They are designed for use in high-temperature and corrosive environments and offer excellent resistance to stress-corrosion cracking and pitting.
What are Incoloy 925 washers, and what are they used for?
Incoloy 925 washers are flat, circular fasteners machined from an age-hardenable nickel-iron-chromium alloy, built to sit under a bolt or nut and distribute load without breaking down in sour, high-chloride, or high-pressure service. Oil and gas wellheads, chemical processing plants, and marine equipment all specify them for the same underlying reason: a joint that holds its clamping force and resists cracking despite sustained exposure to corrosive process media.
Advantages of Incoloy 925 washers
Incoloy 925 washers deliver higher mechanical strength and superior stress-corrosion resistance in demanding sour and chloride-heavy conditions where conventional stainless steel fasteners fail prematurely.
- Superior resistance to stress-corrosion cracking and pitting in sour, chloride-rich environments.
- Age-hardening titanium content gives it strength levels well above standard austenitic alloys.
- Strong oxidation resistance at elevated temperatures keeps clamping force stable under thermal cycling.
- Long service life and dependable performance reduce maintenance downtime and replacement costs.

Frequently Asked Questions
Titanium added to the nickel-iron-chromium-molybdenum base allows age-hardening, giving Incoloy 925 mechanical strength that non-hardenable alloys like 825 can't reach while keeping the same corrosion resistance.
No, it's a non-magnetic austenitic alloy, which matters in applications where magnetic interference needs to stay minimal.
Incoloy 925 washers are used in the oil and gas production, especially high pressure sour wells, and in chemical processing and marine equipment.
The age-hardening treatment of Incoloy 925 results in much higher tensile and yield strength than 825, making it the preferred choice where corrosion resistance and mechanical load capacity are both important.
Yes, fasteners of the same grade prevent galvanic corrosion problems of dissimilar metals in the same joint.
