The differences between carbon steel and stainless steel

The differences between carbon steel and stainless steel

Posted:2022-01-10 10:38:15

1. Different colors: stainless steel contains more chromium and nickel metals, and the exterior color is mostly bright silver. Carbon steel is mainly carbon and iron alloy, and other metal elements are relatively small. The main color of the outer surface is the color of iron, and the color will be much darker.

2. Different textures: stainless steel contains many other metal elements, and the surface is smooth, while carbon steel contains more iron and carbon, which has the essence of iron, and the surface is not as smooth as stainless steel.

3. Different magnetism: the surface of carbon steel is magnetized and can be attracted by magnets. Stainless steel has no magnetism under normal conditions and will not be attracted by magnets.

4. Different carbon elements: carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content of steel, and generally do not add a large amount of alloy metal elements, in which the carbon content WC is less than 2%. In order to maintain corrosion resistance, stainless steel contains carbon content. Both are low, and the maximum does not exceed 1.2%.

5. Different alloy content: carbon steel contains few alloying elements, only a small amount of silicon, manganese, sulfur, and phosphorus. Stainless steel contains a lot of gold elements, and the main chromium and nickel elements exceed 12%.

6. Different corrosion resistance: carbon steel contains less alloying elements and has weak corrosion resistance, while stainless steel contains more chromium-nickel metal, which has strong corrosion resistance.
