5 Differences Between Aluminized Steel and Stainless Steel

No matter what application you need steel for, you can count on us to provide you with the right products at your precise specifications to help your business run smoothly and efficiently. But what is the difference between these two types of steel. Let’s take a quick look at the five main differences between Aluminized Steel and Stainless Steel.

Steel Composition

Aluminized Steel is a carbon steel with an aluminum-silicon alloy coating that adds corrosion resistance and extra strength. Stainless steel is a different alloy that is made of iron, chromium, and often nickel that is highly resistant to rust and corrosion.

Corrosion Resistance

Aluminized Steel has an aluminum coating that is resistant to corrosion in high-temperature environments, though it may be vulnerable in highly corrosive or moist environments if the coating is damaged. Stainless Steel offers corrosion resistance in marine or acidic conditions due to the presence of chromium.

Heat Resistance

With an aluminum coating that helps reflect heat, Aluminized Steel can withstand high temperatures, making it a great option for exhaust systems and ovens. Stainless Steel offers better heat resistance and can withstand higher temperatures without serious corrosion or deformation.

Strength and Durability

Aluminized Steel is strong but can be vulnerable to mechanical wear, especially if the aluminum coating has been damaged or compromised in any way. Stainless Steel has a higher tensile strength that makes it a great choice for structural applications or environments in which mechanical stress is a concern.

Appearance and Aesthetics

Aluminized Steel has an aluminum coating that creates a matte, silver finish which can degrade or discolor over time due to high heat or corrosive environments. Stainless Steel has a smooth, shiny, polished appearance that can be maintained with proper care for aesthetic applications.
