S55C is a high-carbon steel known for its high strength, excellent wear resistance, and superior hardness after heat treatment. It is often used in applications that demand high surface hardness and good mechanical properties. S55C is ideal for components that require a balance of toughness and strength, especially in high-stress environments.
Key Characteristics:
Composition: Contains approximately 0.52-0.58% carbon, along with small amounts of manganese, silicon, and other trace elements.
Strength: Very high strength, which can be further enhanced with heat treatments such as quenching and tempering.
Hardness: Capable of achieving high surface hardness, making it suitable for wear-resistant applications.
Machinability: Moderate; machining requires careful handling due to high hardness.
Weldability: Limited; requires special attention with preheating and post-weld heat treatment to avoid cracking.
Common Applications:
Heavy-duty shafts, gears, and axles
Dies and cutting tools
Springs and wear-resistant parts
Machine components that require high durability
S55C carbon steel is favored in industrial applications where high strength, wear resistance, and surface hardness are crucial, making it a preferred material for manufacturing durable and high-performance mechanical parts.
