Medium-Carbon Steels

 Medium-carbon steels are those steels that have between 0.25 and 0.60% carbon.

MEDIUM-CARBON STEELS

1. What are Medium-Carbon Steels?

✓ Medium-carbon steels are those steels that have between 0.25 and 0.60% carbon.

✓ The medium-carbon steels may be heat treated by austenitizing, quenching, and then tempering to improve their mechanical properties.

2. Characteristics of Medium-Carbon Steels

The main properties of medium-carbon steels are as follows:

1. The plain medium-carbon steels have low hardenabilities.

2. In plain medium-carbon steels, the high strength and hardness properties are achieved (at the sacrifice of ductility and toughness).

3. Applications of Medium-Carbon Steels

Typical applications of medium-carbon steels include railway wheels, railway tracks, gears, crankshafts, and other machine parts.
