Machine-processed carbon steel shaft
After turning, milling, grinding and other processing methods, the dimensional accuracy is high, and it is used in high-precision equipment and aerospace shafts.
Low Carbon Steel (C ≤ 0.25%)
Good plasticity and toughness, easy processing, excellent welding performance, but low hardness and strength, general wear resistance, used in ordinary mechanical shafts, structural shafts, and low-speed shafts.
Medium Carbon Steel (C = 0.25% - 0.6%)
High mechanical strength and hardness, can be improved by quenching and tempering, with certain toughness and wear resistance, suitable for medium load applications.
High Carbon Steel (C = 0.6% - 1.0%)
High hardness, strong wear resistance, but low toughness, large brittleness, mainly used for high-precision, high-wear-resistant parts.
Plain Carbon Steel
Mainly composed of iron (Fe), carbon (C), silicon (Si), manganese (Mn), and does not contain special alloy elements.
Alloy Carbon Steel
Adding chromium (Cr), nickel (Ni), molybdenum (Mo) and other elements to carbon steel to improve strength, wear resistance and corrosion resistance.
Customization of Carbon Steel Shaft
Size customization: Determine the diameter, length, keyway size, etc. of the carbon steel shaft according to the equipment space and transmission requirements.
Shape customization: In addition to the common cylindrical shape, it can also be designed into a conical shape, spline shaft and other shapes according to special needs.
Structure customization: Various mounting structures can be designed on the shaft, such as bosses, steps, threads, etc., so as to install transmission parts such as gears, pulleys, couplings, etc.
Carbon content selection: Select carbon steel with a suitable carbon content according to the requirements for strength, hardness and toughness.
Alloy element addition: Alloy elements such as chromium (Cr), nickel (Ni), and molybdenum (Mo) can be added to further improve performance.
Quenching: The hardness and strength of carbon steel shafts can be improved by quenching.
Tempering: Tempering after quenching can eliminate internal stress, stabilize the structure and size, and improve toughness.
Normalizing: Used to improve the cutting performance of low-carbon steel, refine the grains, and improve strength and toughness.
Nitriding treatment: A nitride layer with high hardness, good wear resistance and strong corrosion resistance can be formed on the surface of the carbon steel shaft.
Hard chrome plating: It can improve the hardness and finish of the shaft surface, reduce the friction coefficient, enhance wear resistance and corrosion resistance, and is often used in occasions with relative movement and low friction requirements.
Blackening treatment: It is mainly for rust prevention and beauty. A black oxide film is formed on the surface of the shaft. It can be used in some occasions with certain requirements for appearance and relatively good working environment.
Forging process: By performing multiple upsetting and drawing operations on the blank, the internal structure of the metal is improved and the comprehensive performance of the shaft is improved.
