Are Steel Rolling Shafts Made from SCM440H or Other Materials?

1. What Are Steel Rolling Shafts?

There are various types of steel rolling shafts, notably:

- Rolling shafts for U- or V-shaped steel

- Ribbed rolling shafts for construction steel

- And others depending on the application

2. Operating Principles and Working Environment of Rolling Shafts

Rolling shafts operate by generating force to directly act on the material, deforming it according to specific requirements.

These shafts work in environments characterized by high friction and wear, as well as significant torsional forces (reaction forces). Thus, they must be durable, resilient, and elastic within predefined limits, while maintaining high hardness and resistance to friction.

3. What Material Is Suitable for Steel Rolling Shafts?

Given these requirements, SCM440H steel is an ideal material for steel rolling shafts.

The inclusion of chromium and nickel in SCM440H enhances the wear resistance of the rolling shafts:

- Chromium content (0.9%–1.2%): Improves wear resistance significantly.

- Nickel content: Increases hardness and provides a polished, shiny finish to the product.

- Molybdenum content (0.15%–0.3%): Enhances the product's heat resistance.

The combination of chromium and molybdenum balances hardness and ductility, reducing the risk of cracking or breaking.

Applications Beyond Steel Rolling Shafts

In addition to steel rolling shafts, SCM440H steel is versatile and can be used for various shaft types, such as:

- Sugarcane pressing shafts.

- Steel straightening shafts

- Pellet press shafts.

With this information, Sevit hopes you have a clearer understanding of SCM440H steel and why it is an excellent choice for steel rolling shafts.
