Provide Comprehensive Range Of High Performance 4130 Steel Popular Materials - China

4130 steel, also known as AISI 4130 or S30CD4, is a widely used medium carbon alloy structural steel known for its **high strength, toughness and weldability**.

It is commonly used for structural parts, vehicles and aerospace components where high strength and good toughness are required.

Here is a comprehensive introduction to 4130 steel: Main ingredients:

- **Carbon (C)**: 0.28-0.33%

- **Manganese (Mn)**: 0.4-0.6%

- **Silicon (Si)**: 0.15-0.35%

- **Chromium (Cr)**: 0.8-1.1%

- **Molybdenum (Mo)**: 0.15-0.25%

- **Phosphorus (P)**: ≤0.035%

- **Sulfur (S)**: ≤0.040% Physical and mechanical properties:

1 - **Density**: about 7.8 g/cm³

2 - **Melting point**: about 1482°C

3 - **Tensile strength**: usually between 700-850 MPa (depending on heat treatment state)

4 - **Yield strength**: usually between 550-700 MPa

5 - **Elongation**: usually between 15-20%

6 - **Hardness**: Depending on the heat treatment state, the hardness can range from 200 HB to 300 HB Application areas:

4130 steel is widely used in many industries due to its excellent comprehensive properties:

1 - **Aerospace**: Manufacturing aircraft frames, landing gear and other key structural components.

2 - **Automotive industry**: Used to manufacture racing car frames, suspension systems and roll cages.

3 - **Mechanical engineering**: Used to manufacture high-strength mechanical parts and tools.

4 - **Military**: Used to manufacture tank armor, weapon systems and military vehicles.

5 - **Bicycles and motorcycles**: Used to manufacture high-strength frames and suspension systems.

In general, 4130 steel is a versatile, high-performance material suitable for a variety of application scenarios requiring high strength, toughness and weldability.
