C45 Carbon Steel – Medium Carbon Steel with High Strength & Durability

C45 Carbon Steel is a premium medium carbon steel grade known for its excellent strength, durability, and reliable mechanical performance in industrial applications.
The balanced chemical composition of C45 Carbon Steel with carbon, silicon, and manganese provides superior hardness, toughness, and machining capability.
Carbon content ranging from 0.42–0.50% gives C45 Carbon Steel high tensile strength, making it suitable for demanding engineering work.
Silicon content of 0.17–0.37% improves structural stability and enhances overall material performance during fabrication.
Manganese content between 0.50–0.80% increases toughness and wear resistance for long-lasting industrial use.
Low phosphorus and sulfur levels (≤ 0.035%) ensure excellent material purity, improved machinability, and dependable operational performance.

High carbon content in C45 Carbon Steel ensures excellent hardness and strength for heavy-duty industrial applications.
Balanced silicon composition improves durability and dimensional stability during machining processes.
Enhanced manganese levels provide better toughness and resistance to mechanical stress.
Low phosphorus content ensures structural consistency and reduces brittleness risks.
Controlled sulfur composition supports smooth cutting and easy fabrication performance.
C45 Carbon Steel is suitable for shafts, gears, bolts, machine components, and precision engineering applications.
