Does carbon steel rust?

Yes, carbon steel rusts. The iron in carbon steel reacts with oxygen to form iron oxide (aka rust), which is particularly prone to rust in humid environments. However, carbon steel rusts relatively slowly and can be slowed down to some extent by surface treatment.

In order to prevent rust of carbon steel, the following measures can be taken:

1. Surface treatment: surface treatment can be used to prevent rust of carbon steel by electroplating, spray painting, plastic spraying, galvanized and other ways of treatment.

2. selection of stainless steel: stainless steel added chrome and other alloy elements, can effectively prevent steel rust.

3. Anti-corrosion treatment: In some special occasions, anti-corrosion coating or other anti-corrosion measures can be used to prevent steel rust.

Even if the anticorrosive treatment, can not completely avoid the rust of carbon steel, so the need for regular inspection and maintenance, timely treatment of steel surface rust.
