How Aluminized Steel is Different from Stainless Steel

Client in several different industries rely on Block Steel to provide quality aluminized steel and stainless steel for a variety of different applications. These two types of steel are very different, but can be beneficial depending on the nature of the project you need it for. In today’s post, we will compare stainless and aluminized steel to help you determine which may be the best option for your company’s needs.

Composition & Coating

Stainless Steel is composed primarily of iron, at least 10.5% chromium, nickel, and possibly other elements that can help improve corrosion resistance.

Aluminized Steel is a carbon steel that is coated with an aluminum-silicon alloy that improves the steel’s resistance to heat and corrosion.

Corrosion Resistance

The chromium content in Stainless Steel makes it highly resistant to rust and corrosion, which is why it is preferred for use in harsh environments.

While Aluminized Steel is more resistant to corrosion than normal regular carbon steel, it can wear down over time, especially in environment with a higher possibility of corrosion.

Heat Resistance

Stainless Steel can withstand high temperatures with a lower risk of degradation.

Aluminized Steel does have good heat resistance qualities because of its aluminum coating, but the coating can be degraded with prolonged exposure to extreme heat.

Strength & Durability

Stainless Steel is a strong, durable material that is great for use in structural and industrial applications.

Aluminized Steel has sufficient strength for applications like auto exhaust systems and ovens, though it is vulnerable to mechanical wear over time.

Cost

Due to its material composition and durability, Stainless Steel is more expensive than Aluminized steel, which is more affordable and cost-effective for applications where extreme durability is not a requirement

Applications

Stainless Steel is used in a wide array of applications like medical instruments, kitchen appliances, construction, and marine environments.

Aluminized Steel is a popular choice for applications that require moderated corrosion and heat protection, like automotive exhausts, ovens, and HVAC systems.
