Inconel high-temperature alloy

Inconel is a high-performance nickel-based superalloy known for its exceptional resistance to high temperatures, oxidation and corrosion. The alloy is primarily composed of nickel (Ni), chromium (Cr) and iron (Fe), making it indispensable in extreme conditions such as high temperatures, pressures and aggressive chemical environments. Unlike ordinary steel, although the melting point of steel may be higher than that of nickel, it will quickly lose strength and corrosion resistance at high temperatures; nickel-chromium iron alloys can still maintain excellent mechanical properties in a hot state and form a dense protective oxide layer to effectively resist high-temperature corrosion.

With excellent mechanical strength, thermal stability and durability, Inconel is widely used in aerospace, energy, chemical and marine engineering fields.

Inconel 617

Inconel 617 (GH617) is a nickel-chromium-cobalt-molybdenum alloy designed to provide excellent strength and corrosion resistance at high temperatures. It exhibits excellent resistance to oxidation and carburization under cycling conditions up to 1100°C, making it ideal for extreme temperature environments. The alloy maintains excellent mechanical properties under both short-term and long-term high-temperature loading, ensuring structural integrity and durability in heavy industry.

Frequently Asked Questions (FAQ)

What is the ingredient system of Inconel 617? What brand does it correspond to in China?

617 is a nickel-chromium-cobalt-molybdenum superalloy: nickel ≥44.5%, chromium 20-24%, cobalt 10-15%, molybdenum 8-10%, iron is limited to ≤3%, and corresponds to GH617 in China. The addition of a large amount of cobalt and molybdenum significantly improves the high-temperature strength and corrosion resistance. The density is 8.4 g/cm³, the melting point is 1330-1380°C, and it takes the ultra-high temperature route.

How high a temperature can Inconel 617 withstand?

What are the thermophysical properties of Inconel 617?

What are the characteristics of Inconel 617's performance under short-term and long-term high temperature loads?

The characteristic of 617 is that it is stable at both ends: it can withstand instantaneous impact without failure under short-term high-temperature load; under long-term high-temperature load, it relies on excellent oxidation resistance and anti-carburization capabilities to maintain structural integrity and is not easily degraded due to oxidation loss or carburization. This short-term plus long-term stability makes it a reliable choice for high-temperature equipment in heavy industry.

In what industries is Inconel 617 (GH617) mainly used? What form can it provide?

617 is commonly used in extreme temperature situations such as gas turbines, industrial furnaces, petrochemical high-temperature furnace tubes, etc. Its durability is ensured by its oxidation resistance, anti-carburization and stable high-temperature mechanical properties under 1100°C cycle conditions. Complete supply forms: plate thickness 0.5-100 mm, rod diameter 5-500 mm, seamless tube outer diameter 6-273 mm, wire 0.1-10 mm.
