What is carbon steel made of?
So-called carbon steel actually means the mechanics performance depends on is the carbon content in steel, general not add master alloy elements of the steel is also known as general carbon steel or carbon steel, and also called carbon steel, carbon steel means the carbon content WC is less than two percent of the iron carbon alloy, carbon and carbon steel in addition to outside, also contains a small amount of materials such as silicon, manganese, sulfur and phosphorus.
Generally carbon steel with higher carbon content will be harder and stronger, but the plasticity will be lower.
What are the advantages and disadvantages of carbon steel?
advantages
1. Higher hardness and better wear resistance of carbon steel can be obtained after heat treatment.
2. The hardness of carbon steel in annealed state is very moderate, and it has good machinability.
3, carbon steel raw materials are very common, simple and easy to obtain, and the cost of production is relatively low.
disadvantages
1, the thermal hardness of carbon steel will be poor, because when the working temperature of the tool is more than two hundred degrees, its hardness and wear resistance will drop sharply.
2, the hardenability of carbon steel is very low, water quenching completely quenched the diameter of the general in 15-18 mm, and for the diameter or thickness is only about 6 mm, so it will be relatively easy to deformation and cracking.
What are the classifications of carbon steel
1, according to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and easy to cut structural steel these three categories.
2. According to the smelting method, carbon steel can be divided into open hearth steel, converter steel and electric furnace steel.
3. According to the method of deoxidation, carbon steel can be classified into efferrescent steel, killed steel, semi-killed steel and special killed steel, which are denoted by code F, Z, B and TZ respectively.
According to the carbon content, carbon steel can be divided into low carbon steel, medium carbon steel and high carbon steel.
5. According to the content of sulfur and phosphorus, carbon steel can be divided into ordinary carbon steel with higher content, high-quality carbon steel with lower content of phosphorus and sulfur, and high-grade high-quality steel with lower content of phosphorus and sulfur, and finally there is a super grade of high-quality steel these four categories.
