The differences between carbon steel and stainless steel

Carbon steel refers to an iron-carbon alloy with a carbon content of less than 2% WC. Carbon steel generally contains a small amount of silicon, manganese, sulfur, and phosphorus in addition to carbon. Stainless steel can resist atmoSPHEric corrosion.

The differences between carbon steel and stainless steel:

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

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