Product Description:
C50 is a medium carbon steel (with a carbon content of approximately 0.50%) that is widely used in the manufacturing of mechanical and structural components requiring moderate strength, hardness, and wear resistance. It is a non-alloy steel that can be heat-treated to improve its mechanical properties. The steel is commonly used in industries like automotive, machinery, and construction for parts such as shafts, gears, axles, and other mechanical components.
Features:
- Good Strength and Hardness: C45 is suitable for parts requiring a balance of hardness and toughness, achieving good strength after heat treatment.
- Excellent Machinability: It offers good machinability in both its annealed and hardened states
- Heat Treatment Capability: It can be heat treated to increase its mechanical properties, including tensile strength, hardness, and wear resistance.
- Versatile: It is used for a wide range of applications, from structural components to mechanical parts and automotive parts.
- Good Toughness: C45 steel retains good toughness, which makes it suitable for applications subject to impact.
Specifications:
- DIN 17200: A German standard for steel grades, which includes C50 steel for mechanical applications.
- EN 10083-2: European standard for steel used in quenching and tempering, applicable to C50.
- UNS G10500: The Unified Numbering System (UNS) designation for C50 steel.
- ISO 683-2: International standard for heat-treated steels, which includes C50 for various mechanical applications.
