The difference between carbon steel and stainless steel
1. The density of carbon steel and stainless steel is different: the density of carbon steel is slightly higher than that of stainless steel
2. The electrical resistance of carbon steel and stainless steel is different: the electrical resistivity increases in order of carbon steel, ferritic, martensitic and austenitic stainless steel.
3. The linear expansion coefficients of carbon steel and stainless steel are different: the order of linear expansion coefficients is also similar, with austenitic stainless steel being the highest and carbon steel being the smallest.
4. The magnetic properties of carbon steel and some stainless steels are different: carbon steel, ferritic and martensitic stainless steels are magnetic, austenitic stainless steels are non-magnetic, but they will produce magnetism when they are hardened by cold work to form martensite transformation. Heat treatment can be used to eliminate this martensite structure and restore its non-magnetic properties.
Stainless steel and carbon steel belong to the same body, and both are steel . steel containing only carbon is called carbon steel, while stainless steel is a steel with high content alloy added for rust prevention. The following is a detailed introduction to the difference between the two.
Resistance to Corrosion:
Stainless steel refers to an alloy that is resistant to weak corrosive media such as air, steam, and water, and chemically aggressive media such as acids, alkalis, and salts. And this function is mainly attributed to the addition of stainless element-chromium. When the chromium element content is greater than 12%, an oxide film will form on the surface of the stainless steel, commonly known as a passivation film. With this oxide film, it will be difficult to dissolve in certain 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%. It is also called carbon steel. Its hardness is much higher than that of stainless steel, but it has a larger weight and lower plasticity. It is typically "excessively rigid and easy to break". Rusty.
Stainless steel contains more chromium and nickel, its appearance is mostly bright silver, and the surface is smooth with strong metallic luster.
Carbon steel is mainly carbon and iron alloy, and other metal elements are relatively few. The main color of the outer surface is the color of iron, which will be much darker, and the surface is not as smooth as stainless steel.
A large number of other alloys are mixed with stainless steel, So stainless steel price is more expensive than carbon steel.
