Stainless steel 347 is an austenitic stainless steel with niobium addition, which provides improved high-temperature strength and corrosion resistance. Here are ten common applications of 347 stainless steel:

Aircraft and Aerospace Components:

347 stainless steel is used in the aerospace industry for components such as exhaust systems, jet engine parts, and other structures that require high-temperature strength and corrosion resistance.

Chemical Processing Equipment:

In the chemical industry, 347 stainless steel is employed for the manufacturing of reactors, heat exchangers, and piping systems where resistance to corrosive chemicals and elevated temperatures is crucial.

High-Temperature Furnaces:

347 stainless steel is suitable for use in high-temperature furnaces and heat treatment equipment due to its excellent high-temperature strength and resistance to oxidation.

Oil Refining Equipment:

Components in oil refining processes, such as catalytic cracking units and distillation columns, may use 347 stainless steel due to its resistance to corrosion in high-temperature and corrosive environments.

Power Generation:

Power plants, especially those using fossil fuels, may use 347 stainless steel in components exposed to high temperatures, such as boiler tubes, superheaters, and turbine parts.

Heat Exchangers:

347 stainless steel is commonly used in the manufacturing of heat exchangers for various industries, including chemical processing, petrochemical, and power generation.

Automotive Exhaust Systems:

Similar to some other high-strength stainless steels, 347 is used in automotive exhaust systems where corrosion resistance and high-temperature strength are essential.

Food Processing Equipment:

The food and beverage industry may use 347 stainless steel for equipment like storage tanks, processing machinery, and piping systems where corrosion resistance and hygiene are critical.

Pressure Vessels:

347 stainless steel can be employed in the construction of pressure vessels, particularly those operating at elevated temperatures, where strength and corrosion resistance are important.

Welded Components:

Due to its good weldability, 347 stainless steel is often used in welded components such as pipes, fittings, and structural elements in various applications.
As with any material selection, it's crucial to consider the specific requirements of each application. We should evaluate factors such as temperature, corrosion resistance, mechanical properties, and cost to ensure the suitability of 347 stainless steel for a particular use project.
