Alloy X-750 vs. Inconel Alloy X-750: Chemical Composition, Durability, and Applications
In this guide, we’ll break down what Zeron 100 is, its chemical properties, comparisons with other Monel materials and industrial applications
Alloy X-750 and Inconel Alloy X-750 are both high-performance nickel-based alloys designed for extreme environments where temperature resistance, mechanical strength, and corrosion resistance are required. These materials are commonly used in aerospace, power generation, and chemical processing industries. In this comparison, we’ll discuss their chemical compositions, durability, and key applications to help you understand which alloy is best suited for your project.
What is Alloy X-750?
Alloy X-750 is a nickel-chromium superalloy used in high-temperature applications due to its excellent oxidation resistance, strength, and long-term durability. It is commonly found in gas turbines, heat exchangers, and other applications where materials are exposed to high stress and heat. This material provides outstanding performance in applications that require resistance to both heat and corrosion at temperatures up to 1300°F.
- Nickel (70%): Provides outstanding resistance to oxidation and high-temperature strength.
- Chromium (15%): Enhances corrosion and oxidation resistance.
- Molybdenum (0.9%): Improves creep resistance and high-temperature stability.
What is the Inconel Alloy X-750?
Inconel Alloy X-750 is a variant of Alloy X-750, but it incorporates additional elements such as titanium and aluminium, which enhance its high-temperature properties. Like Alloy X-750, it is used in environments where resistance to oxidation and creep is critical, but its added elements improve its performance in extreme temperatures and harsh conditions.
- Nickel (70%): The primary element contributing to its high strength at elevated temperatures.
- Chromium (15%): Improves its resistance to corrosion and oxidation.
- Molybdenum (1.2%): Enhances high-temperature creep resistance.
- Titanium (0.3%) and Aluminum (0.3%): Improve strength and resistance to high-temperature oxidation.
Inconel Alloy X-750 is often chosen for applications that demand superior thermal stability and long-term durability under extreme conditions.
