The difference between carbon steel and stainless steel:
①Corrosion resistance, stainless steel is more corrosion resistant than carbon steel.
②ductility, stainless steel is more ductile than carbon steel.
③ Cost gap, stainless steel is more valuable.
④ The difference in use, carbon steel is mostly used for springs, low-speed wheels, etc., stainless steel is more widely used in anti-theft nets and kitchen utensils.
⑤ Color difference, carbon steel color is black, stainless steel is silver.
Why is stainless steel more corrosion resistant than carbon steel? In fact, we can see some clues from the name. The name of stainless steel describes its characteristics to a certain extent, it is not easy to rust. As for why stainless steel is not easy to rust, it is mainly because chromium is added to stainless steel, and chromium is a metal element that increases the corrosion resistance of metal, so stainless steel is more corrosion resistant than carbon steel.
As to why stainless steel is more ductile than carbon steel, it is mainly related to another element. Yes, that element is nickel. Nickel is a ductile and ferromagnetic metal element, and in carbon steel and stainless steel, the nickel element in stainless steel is much more than that in carbon steel, so stainless steel is also stronger than carbon steel in terms of ductility. Regarding ductility, we can understand that it means that the metal can be pressed thinner.
In terms of strength, carbon steel is better than stainless steel, but because stainless steel has strong corrosion resistance, the production process of stainless steel is more complicated, and more materials are added, so it is also higher in cost than carbon. Steel. In life, our stainless steel is mostly used in kitchen utensils, knives, and some special items. One of the reasons for choosing it is because it is not easy to rust.
