The C45

C45 is a material number for a non-alloy structural steel with the designation EN 1.0503. It is a commonly used material in metal processing and is known for its good strength, toughness, and wear resistance.

There are different variants of C45, characterized by various manufacturing processes and properties. Some of them include:

1. C45E: This variant has improved toughness due to the addition of sulfur and phosphorus.

2. C45R: This variant exhibits enhanced wear resistance and is achieved through a special heat treatment.

3. C45+N: The "+N" denotes normalized treatment, leading to improved strength and toughness.

4. C45+C: The "+C" indicates cold-drawn processing, resulting in improved surface quality and dimensional accuracy.
