Depending on the Inconel alloy model, its high temperature resistance varies. Let's take a closer look at the high temperature resistance of Inconel alloy.
1. Inconel 600
Inconel 600 (also known as Inconel 600 alloy) is an alloy containing 80% nickel and 15% chromium, with good high temperature resistance.
High temperature resistance: Inconel 600 can work for a long time at a temperature of up to 1093°C (2000°F). In the short term, Inconel 600 can withstand higher temperatures, but it is best to keep it between 800°C and 900°C for long-term high temperature use to ensure its excellent mechanical properties and oxidation resistance.
2. Inconel 625
Inconel 625 (also known as Inconel 625 alloy) is a nickel-based alloy reinforced with chromium, molybdenum and niobium, with extremely strong high temperature resistance and corrosion resistance.
High temperature resistance: Inconel 625 alloy can be used for a long time at temperatures up to 982°C (1800°F). In some special environments, it can also withstand higher temperatures for a short time.
3. Inconel 718
Inconel 718 (also known as Inconel 718 alloy) is an alloy containing nickel, chromium, iron and molybdenum, widely used in aerospace and high-temperature structural applications.
High temperature resistance: The operating temperature of Inconel 718 alloy is usually below 704°C (1300°F), but it can be used for a short time at temperatures up to 982°C (1800°F). It has good strength and oxidation resistance at high temperatures, so it is widely used in turbines, engines and other components in high temperature environments.
4. Inconel 750
Inconel 750 is an alloy with excellent oxidation resistance and high temperature strength, commonly used in aerospace engines.
High temperature resistance: Inconel 750 can withstand temperatures up to 982°C (1800°F), but the optimal operating temperature range is usually recommended to be controlled at around 760°C (1400°F).
5. Inconel X-750
Inconel X-750 is an alloy with high temperature strength and oxidation resistance, often used for key components in high temperature and pressure environments.
High temperature resistance: The optimal operating temperature of Inconel X-750 is 816°C (1500°F), but it can withstand temperatures of 982°C (1800°F) or even higher in the short term.
6. Inconel 925
Inconel 925 is a high-strength, corrosion-resistant nickel-based alloy that is often used in extremely high temperature and corrosive environments.
High temperature resistance: Inconel 925 alloy can operate for a long time at temperatures up to 982°C (1800°F) and can withstand higher temperatures (in the short term).
7. Summary
The high temperature resistance of Inconel alloy is very good, mainly depending on the specific type of alloy. Generally, Inconel alloy can withstand operating temperatures of 700°C to 1093°C (1300°F to 2000°F), and some types can withstand higher temperature limits under short-term high temperatures.
Inconel 600: up to 1093°C (2000°F)
Inconel 625: suitable for 982°C (1800°F)
