Stainless Steel in Modern Aviation Industry

“The sky has no limits, so the stainless steel”

Global aviation facilitates the connection between people, countries, culture, and so on. The aviation industry limits not just to airplanes, it broadly consolidates airline, aircraft manufacturing, military aircraft, and research-oriented investment companies. The aviation industry heightens the universal economy and business around the world.

Use of Stainless steel in the aviation industry

Modern aircraft are efficient in terms of innovation and engineering. But there are many challenges associated with aircraft designs. The air vehicle works at high altitudes and travels to extreme destinations all around. Aircraft are exposed to different temperatures, extreme climatic changes, corrosions, fuel weight, cargo weight, fires and impact in case of emergency, etc. Commercial flight carries hundred of passengers for long distances at high altitude. The aeronautic engineer designs composite material and components to overcome challenges faced by the aviation industry in conjunction with safety as the utmost priority.

Stainless steel is the most advanced metal for aircraft designs. Aircraft designing needs some of the powerful essential qualities exhibited by stainless steel. Stainless steel has excellent mechanical properties like tensile strength, corrosion resistance, hardness, weldability, thermal expansion, ductility, impact resistance, etc. its exceptional strength makes it significant in applications. It can be welded and machined appropriately for the various parts of aircrafts

Stainless steel is heat, fire, and impact resistance. It can be easily sanitized and maintain durability.  Duplex stainless steel grades are powerful in terms of strength and corrosion resistance. It offers excellent corrosion resistance to a different corrosive atmosphere. Stainless steel has the strength to weight ratio important parameter for passengers and frights. Its nature of stringency relates to the safety and durability of a lifetime.



Applications of stainless steel in aircrafts

Fuel tanks

Fuel tanks are exposed to harsh corrosive chemicals. Stainless steel is an excellent corrosion resistance alloy that protects against high temperatures


Stainless steel fasteners are often used in aircraft designing and work as the linkage between other components. Fasteners are used in the landing gear, wings, engines, and cockpit.

Engine and exhaust parts

Engine and exhaust parts under the pressure of elevated temperature and corrosion resistance. Stainless steel counterparts against the challenges and ensures its safety in long run.

Landing gears

Impact stress and friction forces act into play while landing the aircraft. Stainless steel has high tensile strength and can tolerate impact resistance.

Grades of stainless steel used in the aviation industry

Grade 304 is austenitic and most widely used. It has peculiar mechanical properties like weldability, formability, and machinability. It bestows excellent corrosion resistance.

Grade 321 is also austenitic stainless steel with titanium. It can tolerate high temperatures.

Grade 316 is austenitic stainless steel and famous for superior corrosion resistance in the marine atmosphere.

Grade 410 is martensitic stainless steel and offers wear resistance and tensile strength.

Precipitation hardening stainless steels are also used in aircraft designing, and provide outstanding corrosion resistance and strength.


The metal used in aircraft should be secure, proficient, and consistent for long life. Stainless steel is used in designing and fabrication of various components of aircraft. Stainless steel has a wide scope of creating innovations in the future of aircraft. Engineering techniques are compounded at the ground and fly in the sky. The prospect growth of stainless steel in the aviation industry is taking off. The two best engineering industries are flying in the sky.
