Does Steel Rust? An Overview

Does Steel Rust?

Steel is an incredibly durable material that is used in a wide variety of applications—from construction to manufacturing to automotive. Despite its strength, steel can be vulnerable to the elements. One of the most common issues it faces is corrosion, more commonly known as rust. So, what causes steel to rust? And how can you prevent this from happening? Let’s take a closer look at what makes steel so susceptible to corrosion and how you can protect it.

Why Does Steel Rust?

The simple answer is oxygen. When steel is exposed to oxygen for long periods of time, it will eventually begin to corrode or rust. This process occurs because iron oxide—a compound made up of iron and oxygen—forms on the surface of the steel when oxygen reacts with the iron molecules in the steel’s composition. The formation of iron oxide requires water or moisture in order for it to occur; this means that steel will not rust if there’s no water present.

How Can I Prevent Steel From Rusting?

The best way to prevent your steel from rusting is by keeping it dry and away from any sources of moisture (e.g., rainwater). If you have items that are made out of steel, make sure they are stored in a dry place like a shed or garage with good ventilation so that moisture doesn’t accumulate inside. You should also try to keep your steel items away from any salty environments (such as near bodies of water), as salt accelerates the rusting process even further. Additionally, applying a coat of paint or sealant onto your metal surfaces can help provide an extra layer of protection against moisture and corrosion.


Steel may be strong and durable, but it isn’t immune to corrosion or rusting caused by exposure to oxygen over time—especially when combined with other elements such as water or salt. However, there are ways you can prevent your metal items from developing rust too quickly, such as keeping them in dry areas away from moisture and salt sources and applying a protective coating on them like paint or sealant. By taking these steps now, you can ensure that your metal items will stay looking great for years to come!
