Aviation and Aerospace; two industries that gave flight to each definition of innovation. 

The terms ‘Aviation industry’ and ‘Airline Industry’ might sound the same but their meaning differs, ‘airline’ stands for air transportation services for people or cargo whereas ‘aviation’ is quite weightier as it includes air safety specialists, airliner manufacturers, and massive businesses that create or use drones.

1,75,000 lbs – is what each Aerospace weighs with parts including actuators, fasteners, landing gear, and many others that should withstand complex temperatures and corrosion resistance. 

Stainless Steel helps to cover each of them – in fact, according to a report published by the Federal Aviation Administration, stainless steel can be used in almost any element of aircraft.

Rather, environments turning extremely hot or cold stainless steel extremely benefits both airline and aviation equally with high corrosion resistance and prolonged work durability. 

Uses of Stainless Steel in the Airline Industry

When the word “Airline” comes, the first thing which needs to be considered is its strength which can cross long distances at high altitudes that too with hundreds of people on board. 

And as we are familiar – stainless steel has already marked its title for such parameters with its easy-to-work and low maintenance characteristics that resist the lowest to the highest form of temperatures and even in acidic and marine environments. 

The airline is meant to be considered in such extreme conditions, so the wider the use of stainless steel the wider aerospace durability will be! This high strength requirement multiplies the ratio of stainless steel used in aircraft by offering various sizes and shapes in airline parts that are precisely welded and machined.

As stainless steel signifies corrosion resistance it adds a bookmark to hygiene and durability too, which is considered an important factor in giant aircraft that provide every day and constant transportation services.

Uses of Stainless Steel in Aviation Industry

Manufacturing, maintaining, and operating – aircraft and airports are accomplished by this business sector. As stainless steel offers versatility it can be used by any metallic aircraft part however consideration of aluminum is quite more because of its cost-effectiveness and lightweight factors.

Stainless steel is mostly used for aircraft that need to be heavier in strength or in particular areas where metals can be harmed by corrosion such as fuel tanks, battery boxes, cylinder fins, and many other minute areas which need to be thoroughly inspected. 

In Aviation industries, stainless steel is more likely to be used as key structural components such as actuators, fasteners, and landing gear components. The primary work of these elements is to hold aircraft together, mainly found in the landing gear, the wings, the engines, and the cockpit.

Stainless Steel Grades Used in Aviation and Aerospace Industry

Use of grade SS 304 in aircraft:

When we previously read about stainless steel’s heavy weightage, we might keep stainless steel as a second option for getting in use. Whereas the fact of the matter is stainless steel alloys also offer higher tensile strength, shear modulus, and melting points than aluminum.

Because of its easy welding, formability, machinability, and top of its high-corrosion resistance grade, SS 304 surrounds a huge portion of the manufacturing of aircraft parts.

Use of grade SS 321 in aircraft: 

Grade SS 321 is an ideal and proven grade that can easily withstand temperatures from 800 to 1500°F and resist oxidation up to 1500°F, even in such high temperatures SS 321 reflects its excellent machinability and resistance without getting any structural transformations. 

Aircraft components such as engines, exhaust manifolds, jet engine parts, exhaust ducts, and flanges get exceptional benefits with such physical properties of SS 321 and its durability too.

Use of grade SS 316 in aircraft:

Stainless Steel 316 is authentic stainless steel with an addition of molybdenum chemical element which increases its corrosion resistance and workability even in high temperatures and disputes against sulfurous and phosphoric acids. 

As SS 316 derives it is a powerful grade, and also profits the aerospace industry, likely being unharmed and offering the same work quality even in high temperatures of 1598 degrees Fahrenheit.

Applications of Stainless Steel in Aerospace Industry

• Actuators
• Fasteners
