S45C Carbon Steel Coil is a type of medium carbon steel coil that adheres to the Japanese Industrial Standard (JIS) G4051. This material grade, S45C, is known for its moderate strength and good machinability.
S45C Carbon Steel Coil is a type of medium carbon steel coil that adheres to the Japanese Industrial Standard (JIS) G4051. This material grade, S45C, is known for its moderate strength and good machinability.
Ingredients:
Carbon Steel: The primary composition of S45C Carbon Steel Coil includes iron with a carbon content ranging from 0.42% to 0.50%. It also contains:
- Manganese: Typically up to around 0.6%, which enhances strength and hardenability.
- Silicon: Present in limited amounts to improve strength and deoxidize the steel during production.
- Phosphorus and Sulfur: Kept at low levels (<0.035% each) to ensure good ductility and weldability.
Uses:
- Machine Parts: S45C coils are widely used for manufacturing machine parts like shafts, gears, bolts, nuts, and various mechanical components due to their high tensile strength and excellent machinability.
- Forging Applications: After being processed into blooms or billets, they can be forged into complex shapes for industrial machinery and equipment.
- Cold Rolled Products: Cold rolled S45C coils can be formed into precision parts or further processed into sheets and strips for applications where dimensional accuracy is crucial.
- Welded Fabrication: Although not as common as other lower carbon grades, S45C can still be welded when necessary for specific structural applications requiring higher strength.
In summary, S45C Carbon Steel Coils offer an ideal balance between strength, hardness, and machinability, making them suitable for producing high-quality machine parts and components across various industries. While welding may require extra precautions due to its relatively higher carbon content, it remains a popular choice in applications where wear resistance and moderate toughness are desired.
