Sling quality carbon structural information

Material rigging is divided into high quality carbon steel and ordinary carbon steel, two compared with content of sulfur and phosphorus and other non-metallic inclusions of low. According to the carbon content and the use of different, this kind of steel was also divided into three categories: less than 0.25%C for low carbon steel, especially carbon less than 0.10% of 08F, 08Al and so on, because of excellent deep drawability and weldability and is widely used as deep drawing parts such as the car, can...... Etc.. 20G is the main material for the production of ordinary boiler. In addition, low carbon steel is also widely used as a carburizing steel, used in mechanical manufacturing. 0.25 ~ 0.60%C for medium carbon steel, more in the state of conditioning, the production of machinery manufacturing parts. Greater than 0.6%C for high carbon steel, more for the manufacture of springs, gears, rollers, etc.. According to the different manganese content, it can be divided into ordinary manganese content (0.8% ~ 0.25) and a high manganese content (0.7 ~ 1% and 0.9 ~ 1.2%) two steel group. Manganese can improve the hardening of steel, strengthen the ferrite, improve the yield strength, tensile strength and wear resistance of the steel. Usually in the high manganese steel grades after the mark "Mn", such as 15Mn, 20Mn to distinguish them from normal manganese content of carbon steel.
