How Are Car Clutches Made from SCM440H Steel?

1. What is a Car Clutch?

A clutch, also known as a "disc" or "clutch assembly," is one of the key components of automobiles and tractors.

The clutch connects the engine's crankshaft (flywheel) to the drivetrain system, transmitting torque smoothly while enabling quick and decisive disengagement when needed.

Even when the vehicle is stationary but the engine remains running, a clutch is essential to disconnect power from the engine to the wheels.

2. How Does a Clutch Work?

When the engine starts running, the friction disc is pressed tightly against the flywheel's rotating motion. Under the influence of frictional force, these parts form a unified assembly.

Clutches operate in environments subjected to continuous friction, wear, and heat generation during vehicle operation, making them prone to cracking and breakage.

Thus, a high-quality material is needed to significantly reduce cracking and breakage in components during use.

3. How Are Car Clutches Made from SCM440H Steel?

Since clutches often work under challenging conditions such as exposure to environmental factors like sunlight, rain, and mud, as well as internal factors like high gravity and friction forces, issues like breakage and wear frequently arise during use.

To address these issues, save costs, and extend product lifespan, many companies utilize solid round SCM440H steel.

How SCM440H Steel is Used in Clutch Manufacturing:

SCM440H is a Chromium-Molybdenum steel produced by Hyundai. This steel grade is commonly applied in machine manufacturing and precision mechanical processing, such as gears, anchor bolts, etc.

Solid round SCM440H steel is an ideal material for making clutches for the following reasons:

- Strength and Toughness: It can withstand various forces during operation while maintaining both toughness and hardness.

- Improved Wear Resistance: With approximately 1.2% Chromium content, its wear resistance is significantly enhanced compared to other steel grades.

- Balanced Properties: The combination of Chromium and Molybdenum balances hardness and toughness, reducing the risk of cracking and breakage.

Conclusion:

Through this article, we hope to provide you with essential information about SCM440H solid round steel used in clutch manufacturing to improve product efficiency, extend lifespan, and reduce material costs.
