C38D carbon steel

1. Overview of C38D carbon steel:

C38D carbon steel is a medium carbon steel with moderate carbon content and good plasticity and weldability. It is a commonly used structural steel for the manufacture of mechanical parts, bearings, gears, etc.

2. Chemical composition of C38D carbon steel:

The chemical composition of C38D carbon steel usually includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements. Among them, the content of carbon is about 0.35%-0.42%, the content of silicon is about 0.10%-0.35%, the content of manganese is about 0.50%-0.80%, and the content of phosphorus and sulfur should be less than 0.040%.

3. Mechanical properties of C38D carbon steel:

The mechanical properties of C38D carbon steel show high strength and toughness. Its tensile strength is usually about 600MPa, the yield strength is about 370MPa, and the elongation is about 16%. These properties allow C38D carbon steel to provide excellent mechanical properties in many engineering applications.

4. Heat treatment of C38D carbon steel:

C38D carbon steel can be heat treated to change its properties. Common heat treatment methods include normalizing and quenching. Normalizing can improve the hardness and toughness of the material, while quenching can increase its strength. The C38D carbon steel after heat treatment has good comprehensive mechanical properties and wear resistance.

5. C38D carbon steel application field:

Because C38D carbon steel has good mechanical properties and heat treatment plasticity, it has been widely used in many fields. It is often used in the manufacture of mechanical parts, auto parts, molds and so on. At the same time, C38D carbon steel is also commonly used in the manufacture of tools and tools that require high hardness and strength.
