Stainless steel and carbon steel are relatively common metal materials, so what are the differences between stainless steel and carbon steel?

1. Different appearance

Stainless steel is mainly composed of chromium and nickel elements, so the appearance of the product is mostly silver and bright, and the surface is smooth and shiny. Carbon steel metal is mainly composed of carbon and iron elements, so the appearance of the product is mostly black, and its surface is relatively dull, and it is not as smooth and shiny as the surface of stainless steel.

2. Different corrosion resistance

The corrosion resistance of stainless steel is better than that of carbon steel, because stainless steel metal contains more chromium, and chromium reacts with oxygen to form a chromium oxide layer on the surface of stainless steel to prevent the metal from being corroded. However, the surface of carbon steel cannot form a chromium oxide layer, so its corrosion resistance is relatively poor.

3. Different wear resistance

The wear resistance of carbon steel is better than that of stainless steel, because the hardness of carbon steel is higher than that of stainless steel, and its plasticity is lower, so it will be more wear-resistant.

4. Different magnetic properties

Carbon steel is more magnetic than stainless steel because of its high iron content. Stainless steel is mostly non-magnetic or weakly magnetic products, because stainless steel usually contains nickel, which inhibits or removes the magnetism of the product.

5. Different ductility

The ductility of stainless steel is better than that of carbon steel, because stainless steel has a high content of nickel, which has good ductility, so the ductility of stainless steel is also good. Carbon steel contains very little nickel, which can be ignored, so the ductility will be relatively poor.

6. Different prices

The price of stainless steel is more expensive than carbon steel, because stainless steel will add a lot of alloys in the production process, its cost is high, and the price is also expensive. In the production process of carbon steel, less alloy is added, and the cost will be relatively lower.
