NS322 Alloy is a high-performance nickel-based superalloy designed for applications that demand exceptional strength, corrosion resistance, and thermal stability. It is widely used in high-temperature environments where reliability and durability are critical.
Composition:
NS322 Alloy consists of:
- Nickel (Ni): 50 - 60%
- Chromium (Cr): 20 - 25%
- Molybdenum (Mo): 8 - 12%
- Iron (Fe): ≤ 10%
- Cobalt (Co): ≤ 5%
- Titanium (Ti): 1 - 2%
- Carbon (C): ≤ 0.08%
- Manganese (Mn): ≤ 1%
- Silicon (Si): ≤ 0.5%
High-Temperature Performance:
NS322 Alloy is engineered to perform reliably at elevated temperatures, typically ranging from 1300°C to 1400°C. Its high melting point and ability to retain mechanical strength make it ideal for use in gas turbines, heat exchangers, and other high-temperature applications.
