〣Description of carbon plate
Mainly refers to the carbon mass fraction less than 2 percent, 11 percent of the steel without specially added alloying elements. Sometimes called plain carbon steel or carbon steel.
Carbon steel, also known as carbon steel, refers to the carbon content of less than 2 percent, 11 percent of the iron carbon alloy. In addition to carbon steel generally contains a small amount of silicon, manganese, sulfur, phosphorus.
Carbon steel according to the name of the main classification: pig iron, carbon structural steel, high quality carbon structural steel, low alloy structural steel, alloy structural steel, spring steel and bearing steel, tool steel, stainless steel and heat resistant steel and so on.
〣High carbon steel plate
Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. Also known as carbon steel. Generally also contains a small amount of silicon, manganese, sulfur, phosphorus. Generally, the higher the carbon content of carbon steel, the greater the hardness, the higher the strength, but the lower the plasticity.
〣The main element of carbon steel plate
Carbon (C) : With the increase of carbon content in steel, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content exceeds 0.23%, the welding performance of steel deteriorates. Therefore, the carbon content of low-alloy structural steel used for welding generally does not exceed 0.20%. High carbon content will also reduce the atmospheric corrosion resistance of steel, high carbon steel in the open pit is easy to rust; In addition, carbon can increase the cold brittleness and aging sensitivity of steel.
Silicon (Si) : Silicon is added as a reducing agent and deoxidizer in the steelmaking process, so the sedated steel contains 0.15-0.30% silicon. If the silicon content of the steel exceeds 0.50-0.60%, silicon is considered an alloying element. Silicon is widely used as spring steel because it can significantly improve the elastic limit, yield point and tensile strength of steel. The strength of tempered structural steel can be increased by 15-20% by adding 1.0-1.2% silicon. Silicon and molybdenum, tungsten, chromium, etc. combine to improve corrosion resistance and oxidation resistance, can be made of heat-resistant steel. Low carbon steel containing 1-4% silicon, with very high permeability, used in the electrical industry to make silicon steel sheet. The increase of silicon will reduce the welding performance of steel.
Manganese (Mn) : In the process of steelmaking, manganese is a good deoxidizer and desulfurizer, the general steel manganese 0.30-0.50%. When more than 0.70% is added to carbon steel, it is considered as "manganese steel". Compared with the general steel, steel not only has enough toughness, but also has higher strength and hardness, improve the quenching of steel, improve the thermal working performance of steel, such as 16Mn steel is 40% higher than A3 yield point. Steel with manganese content of 11-14% has very high wear resistance and is used for excavator bucket, ball mill lining board, etc. The increase of manganese content weakens the corrosion resistance and welding performance of steel.
Phosphorus (P) : In general, phosphorus is a harmful element in steel, which increases the cold brittleness of steel, deteriorates the welding performance, reduces the plasticity, and deteriorates the cold bending performance. Therefore, it is usually required that the phosphorus content in steel is less than 0.045%, and the requirement of high-quality steel is lower.
Sulfur (S) : Sulfur is also a harmful element in general. Make the steel produce hot brittleness, reduce the ductility and toughness of steel, cause cracks in forging and rolling. Sulfur is also bad for welding performance, reducing corrosion resistance. Therefore, sulfur content is usually required to be less than 0.055%, and quality steel is required to be less than 0.040%. The machinability can be improved by adding 0.08-0.20% sulfur to steel, which is usually called free-cutting steel.
