Разница между углеродистой сталью и нержавеющей сталью
Stainless steel and carbon steel belong to one body and are all steel. Сталь, содержащая только углерод, называется углеродистой сталью., а нержавеющая сталь - это сталь с высоким содержанием сплава для предотвращения ржавчины..
1. Anti-corrosion and wear resistance
Stainless steel refers to an alloy that is resistant to corrosion by weak corrosive media such as air, Стим, вода, and chemically aggressive media such as acids, alkalis, and salts. This function is mainly due to the addition of the stainless element – chromium. When the content of chromium element is more than 12%, an oxide film is formed on the surface of the stainless steel, commonly known as a passivation film. With this layer of oxide film, it will not dissolve easily in some media, which has a good isolation effect. Strong corrosion resistance.
Carbon steel refers to an iron-carbon alloy with a carbon content of less than 2.11%, also called carbon steel. Its hardness is much higher than that of stainless steel, but it has a large weight and low plasticity. It is typically “just too easy to fold” and easy. Rusty.
2. Appearance
Also, because stainless steel contains more chromium and nickel metal, the exterior color is mostly silver, and the surface is smooth and has a strong metallic luster.
Carbon steel is mainly carbon and iron alloy, other metal elements are relatively small, the main color of the exterior is iron color, it will be much darker, and the surface is not smooth with stainless steel.
3. Price
A large number of other alloys are mixed with stainless steel, which is more expensive than carbon steel.
