The difference between carbon steel and stainless steel
2022-11-16

1. Appearance difference between carbon steel and stainless steel:

The main components of stainless steel are metals such as chromium and nickel, so the appearance of stainless steel is mostly silver, and its surface is smooth and has a very strong metallic luster.

The main components of carbon steel are carbon and iron alloys, so the color of carbon steel is darker, and the surface is rougher than stainless steel.

2. The difference between carbon steel and stainless steel in terms of corrosion resistance:

Both carbon steel and stainless steel contain iron. Iron oxidizes when exposed to the environment, resulting in rust. And stainless steel has chromium added, which combines with oxygen more easily than iron.

When chromium attaches to oxygen, it forms a layer of chromium oxide that protects the steel from degradation and corrosion. Carbon steel has a low chromium content, and a small amount of chromium cannot form the chromium oxide layer. Therefore, the corrosion resistance of stainless steel is stronger than that of carbon steel.

3. The difference between carbon steel and stainless steel in terms of wear resistance:

The hardness of carbon steel is much higher than that of stainless steel, but the weight is larger and the plasticity is lower. In terms of wear resistance, carbon steel is more wear-resistant than stainless steel.

4. The difference between carbon steel and stainless steel in terms of price:

Since a lot of other alloys need to be added in the process of making stainless steel, and carbon steel does not need to add a lot of other alloys, the price of stainless steel is more expensive than carbon steel.
