Incoloy 800 and Inconel 600 are both nickel-iron-chromium alloys but differ in composition and application. Here’s a comparison of their performance and price:
Состав:
Incoloy 800 (Alloy 800):
- Composition: Primarily nickel, with significant amounts of chromium and iron. Contains small additions of aluminum and titanium for improved high-temperature properties.
- Main Characteristics: Designed for high-temperature applications, oxidation resistance, and carburization resistance.
Inconel 600 (Alloy 600):
- Composition: Nickel-chromium alloy with good oxidation resistance at higher temperatures. Contains iron as the base metal and chromium for oxidation resistance.
- Main Characteristics: Known for its excellent mechanical properties and high strength, along with good resistance to stress-corrosion cracking and good weldability.
Производительность:
- Инколой 800:
- High-Temperature Performance: Excellent resistance to oxidation, carburization, and nitridation in high-temperature environments.
- Устойчивость к коррозии: Good resistance to many corrosive environments, including sulfur-containing atmospheres.
- Creep and Rupture Strength: Maintains good strength and resistance to creep deformation at high temperatures.
- Инконель 600:
- High-Temperature Performance: Resistant to oxidation and scaling up to about 2000°F (1093°C).
- Устойчивость к коррозии: Excellent in a wide range of corrosive media, including oxidizing and reducing conditions.
- Механические свойства: High strength and good fabricability, making it suitable for various industrial applications.
Price:
- Инколой 800 typically tends to be more expensive than Inconel 600 due to its specialized composition and properties designed for high-temperature applications.
- Инконель 600 is relatively more economical, although prices can vary based on market conditions and the specific form (sheet, plate, pipe, etc.).
Приложения:
- Инколой 800: Used in furnace components, petrochemical process equipment, heat-treating equipment, and nuclear power plants where heat resistance and corrosion resistance are critical.
- Инконель 600: Widely used in chemical and food processing, nuclear engineering, furnace components, and for applications requiring high mechanical properties and resistance to corrosion.
Summary:
- Инколой 800 is preferred where high-temperature strength and resistance to oxidation are paramount.
- Инконель 600 is chosen for its excellent mechanical properties and good corrosion resistance across a broad range of environments.
Choosing between Incoloy 800 and Inconel 600 depends largely on the specific application requirements, especially regarding temperature, corrosion environment, mechanical stress, and budget constraints.
