Description:

INCONEL 686 (UNS N06686) is a nickel-chromium-molybdenum alloy designed for applications that require superior resistance to both corrosion and high temperatures. It is particularly noted for its ability to resist sulfuric and phosphoric acids, as well as other aggressive chemicals, even at elevated temperatures.

The alloy's high molybdenum content (8-9%) helps it resist pitting, crevice corrosion, and stress-corrosion cracking in highly corrosive environments. The combination of nickel, chromium, and molybdenum makes INCONEL 686 ideal for use in chemical processing, pollution control, and heat exchangers, where exposure to aggressive chemical agents and high temperatures is common.

INCONEL 686 also provides excellent performance in high-temperature environments, making it suitable for applications such as combustion systems and other high-heat industrial processes.

Applications:

• Chemical Processing: Equipment used for handling sulfuric acid, phosphoric acid, and other corrosive chemicals.
• Pollution Control: Components in systems designed to control emissions and handle highly corrosive gases or chemicals.
• Power Generation: Heat exchangers and other components exposed to high temperatures and corrosive environments.
• Heat Exchangers: Especially in environments where corrosion resistance and high-temperature performance are required.

FAQ

1. What is INCONEL? INCONEL is a family of high-performance, heat-resistant alloys primarily made of nickel, chromium, and iron. These alloys are designed to withstand extreme temperatures and resist oxidation, corrosion, and thermal fatigue, making them ideal for use in high-temperature environments.

 

2. What are the main types of INCONEL alloys? Some of the most common types of INCONEL alloys include:

• INCONEL 600 (UNS N06600): Known for excellent oxidation and carburization resistance, used in heat exchangers, furnace components, and chemical processing.
• INCONEL 625 (UNS N06625): Provides high strength and resistance to fatigue and thermal-fatigue stress, used in aerospace, marine, and chemical industries.
• INCONEL 718 (UNS N07718): A precipitation-hardening alloy with high strength at elevated temperatures, commonly used in aerospace and turbine components.

 

3. What are the properties of INCONEL alloys?

• High Temperature Resistance: INCONEL alloys maintain excellent strength and stability even at high temperatures, often up to 1,100°C (2,000°F).
• Oxidation and Corrosion Resistance: These alloys are highly resistant to oxidation and corrosion in extreme conditions, such as steam, acids, and sulfur gases.
• Strength and Durability: INCONEL alloys exhibit superior tensile strength, creep, and fatigue resistance at both high and low temperatures.

 

4. What are the common applications of INCONEL alloys? INCONEL alloys are widely used in applications where high strength and corrosion resistance at elevated temperatures are essential, including:

• Aerospace: Gas turbine engines, jet engines, and exhaust systems.
• Chemical Processing: Reactors, heat exchangers, and piping systems.
• Power Generation: Components in power plants, such as turbines and boilers.
• Marine: Seawater pumps, marine exhaust systems, and propeller shafts.
• Furnace Components: Heat-resistant elements in furnaces, kilns, and industrial heating equipment.

 

5. How do INCONEL alloys compare to other high-temperature materials?
INCONEL alloys offer superior high-temperature performance compared to other metals such as steel or titanium. They provide better oxidation and corrosion resistance, especially in environments with high heat and aggressive chemicals. They also exhibit greater stability and strength over a wide range of temperatures.

 

6. Can INCONEL alloys be welded?
Yes, INCONEL alloys can be welded using various welding techniques, including TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding. Proper welding procedures are required to maintain the material's high strength and resistance properties, often involving pre-heating or post-weld heat treatment to reduce the risk of cracking.
