The Chemistry Behind Special Steel 10201.0402 Carbon Steel
The chemical composition is like the DNA of the steel. Each element has a specific role:
- Carbon (C): The main hardening element. Increases strength and hardness but too much can reduce toughness.
- Silicon (Si): Helps deoxidize the steel and can improve strength.
- Manganse (Mn): Improves hardenability, wear resistance, and tensile strength.
- Phốt pho (P) and Lưu huỳnh (S): Usually kept low because they can cause brittleness.
- Crôm (Cr) and Niken (Ni): Add strength and toughness. Though present in small amounts here, they enhance the steel’s performance.
- Molypden (Mo): Increases strength and hardness.
- Copper (Cu): Helps in improving corrosion resistance.
By tweaking these elements, manufacturers can tailor the steel to meet specific needs, making it more versatile and reliable.

The Science of Mechanical Properties
The mechanical properties of Special Steel 10201.0402 Carbon Steel are impressive. Here’s a closer look at what each property means:
- Độ bền kéo: This is the maximum stress the steel can withstand while being stretched or pulled before breaking. A high tensile strength indicates the steel can handle substantial forces.
- Yield Strength: The stress at which the steel begins to deform plastically. Beyond this point, it won’t return to its original shape. This is crucial for applications where permanent deformation must be avoided.
- Elongation: This measures the steel’s ability to stretch or elongate before breaking. Higher elongation means better ductility, allowing the material to absorb energy without breaking.
- Độ cứng: Measured in Brinell hardness (HB), this indicates how resistant the steel is to deformation. Higher hardness means better wear resistance.
- Impact Energy: This measures the steel’s toughness, or its ability to absorb energy during impact. Higher values mean better resistance to sudden forces, reducing the risk of brittle failure.
The Importance of Heat Treatment
Heat treatment processes are essential for enhancing the properties of this carbon steel. Here’s why each process is used:
- Ủi nhiệt: This process softens the steel, making it easier to machine and shape. It also relieves internal stresses that could lead to failure.
- Chuẩn hóa: This refines the grain structure, leading to improved mechanical properties and uniformity.
- Hardening: By heating and then rapidly cooling (quenching), the steel’s hardness and strength are significantly increased. This is crucial for applications requiring high wear resistance.
- Ủ nhiệt: After hardening, tempering is used to adjust the steel’s hardness and toughness. It reduces brittleness and ensures the steel can withstand impacts without shattering.
