Inconel Alloys – Unmatched Performance in Extreme Heat and Corrosion
We supply a wide range of Inconel alloys including 600, 625, 718, X-750 for demanding high-temperature and corrosive environments. Trusted by aerospace, power, chemical and marine industries.
What Is Inconel?
Inconel® is a family of nickel-chromium-based superalloys developed by Special Metals Corporation. It is designed for service in extreme environments involving:
High temperature (up to 1000°C).Severe corrosion and oxidation.High pressure or cyclic stress.Saltwater or chemical attack.
Key Properties:
Exceptional thermal fatigue resistance.High creep and rupture strength.Excellent resistance to chloride stress corrosion cracking (SCC).Maintains strength and shape under thermal cycling.
Popular Grades:
Inconel 600 – Oxidation + chloride resistance
Inconel 625 – Strength + seawater + acid corrosion
Inconel 718 – High strength + creep resistance (age-hardenable)
Inconel X-750 – Aerospace, gas turbine, spring applications

Inconel alloy is a nickel-based superalloy widely used in extreme environments due to its superior performance. The following is a detailed analysis of its performance characteristics and applications:
1. Performance Characteristics
The core performance of Inconel alloy stems from the synergistic effect of its nickel-based composition and alloying elements (such as chromium, molybdenum, and cobalt), forming a stable austenitic structure that endows the material with excellent corrosion resistance, high-temperature strength, and oxidation resistance.
1.1 Corrosion Resistance
It exhibits excellent performance in both oxidizing and reducing environments, resisting corrosion from various acid, alkali, and salt solutions. Suitable for strong acid and alkali environments, such as chemical equipment and marine engineering, ensuring long-term stable operation.
1.2 High-Temperature Performance
It maintains high strength at high temperatures, exhibiting excellent creep and fatigue resistance, suitable for extreme temperatures above 1000°C. It has significant oxidation resistance, forming a protective oxide layer and extending service life.
1.3 Mechanical Properties
It combines high strength, high toughness, and high ductility, making it suitable for complex machining and dynamic load scenarios. 1.4 Fatigue Resistance
Excellent weldability, allowing for joining through various processes, facilitating manufacturing and maintenance.
2. Main Applications
Inconel alloys’ unique properties make them the material of choice in several key areas.
2.1 Aerospace
Used in engine components, combustion chambers, and turbine blades, they withstand high-temperature and high-pressure environments, ensuring flight safety.
2.2 Energy Sector
Applications in nuclear reactors and gas turbines, providing stability and reliability, supporting efficient energy conversion.
2.3 Chemical and Marine Engineering
Used in the manufacture of reactors and piping, resisting corrosive media and ensuring equipment integrity.
2.4 Medical Devices

Frequently Asked Questions
Q1: What's the main difference between Inconel 625 and 718?
A:
625 is non-age-hardenable, excellent for corrosion; 718 is age-hardenable, used when high strength and creep resistance are critical, such as in turbines or engines.
Q2: Can Inconel alloys be welded?
A:
Yes. Inconel can be GTAW or GMAW welded using Inconel filler metals like ERNiCrMo-3 or 718 filler.
Q3: Do you provide Inconel sheets for thermal fixtures?
A:
Yes, Inconel 600, 601, and 718 plates are ideal for baskets, trays, and jigs in heat treating processes.
Q4: Do you support cut-to-size and machining?
A:
Absolutely. We offer custom lengths, drilled plates, and CNC-milled components to drawing.
Q5: Are your Inconel products certified?
A:
Yes. MTC + AMS + NACE certifications available. We also support third-party audits and inspection.
