Incoloy Alloys – High-Temperature Corrosion-Resistant Nickel-Iron Alloys
Incoloy alloys are designed for service in extreme environments combining heat, pressure, and corrosive media. Ideal for chemical processing, nuclear, marine, and thermal treatment systems.
What Is Incoloy?
Incoloy® is a family of nickel-iron-chromium-based superalloys manufactured by Special Metals Corporation. Unlike Inconel, which is optimized for oxidation and strength at ultra-high heat, Incoloy offers a balance between:
- High strength at elevated temperatures
- Outstanding resistance to sulfuric and phosphoric acid
- Stress-corrosion and pitting resistance in seawater and chlorides
- Excellent structural stability under thermal cycling
Most Popular Incoloy Grades:
Incoloy 800 / 800H / 800HT – High strength + oxidation resistance
Incoloy 825 – Corrosion resistant in reducing + oxidizing acid
Incoloy 925 / 945 / A286 – High strength and corrosion resistance, often used in oil & gas

Frequently Asked Questions
Q1: What's the difference between Incoloy 800 and 825?
A:
800 is mainly for high-temperature stability and oxidation resistance; 825 is used more for corrosion resistance in acids like sulfuric or phosphoric.
Q2: Can Incoloy 825 be used in seawater?
A:
Yes. It has excellent resistance to seawater corrosion, pitting, and crevice attack, making it suitable for marine systems.
Q3: Do you supply seamless pipes and heavy plates in Incoloy grades?
A:
Yes, we offer both hot-rolled plates up to 100mm and seamless tubes from NPS 1/2” to 20”.
Q4: What is the welding condition of Incoloy alloys?
A:
Most Incoloy grades can be welded using standard nickel-based filler wires (e.g., ERNiCrMo-3) with preheat control.
Q5: Do you offer low MOQ or urgent delivery?
A:
Absolutely. Stocked items can ship in 3–5 days, and small batch trial orders are welcome.
