C45 Steel Coil Has Various Heat Treatment Methods To Optimize Its Performance - China

C45 steel coil is a commonly used medium carbon steel, and its chemical composition mainly includes carbon, silicon, manganese, phosphorus and sulfur.

The carbon content is between 0.42-0.50%, the silicon content is between 0.17-0.37%, the manganese content is between 0.50-0.80%, the phosphorus content does not exceed 0.035%, and the sulfur content does not exceed 0.035%.

The content of these elements makes C45 steel have good mechanical properties, such as hardness, strength and toughness.

C45 steel coil can be optimized through a variety of heat treatment methods.

Common heat treatment methods include normalizing, annealing, quenching and tempering.

Normalizing can improve the mechanical properties of C45 steel coil; annealing helps to improve its machinability; quenching can make C45 steel coil obtain higher hardness and strength; tempering can relieve the internal stress generated by quenching and improve the toughness of steel.

In addition, C45 steel coil can be flame or induction hardened to a minimum surface hardness of 55HRC or higher.
