When selecting the ideal tool steel for mold production, 1. and 1. are often the top options. While they belong to the same family and are widely used, understanding their differences can help you choose the steel best suited for your project.

 

Why Does 1. Excel in Machinability?  

The standout feature of 1. steel is its superior machinability, achieved by adding sulfur to its chemical composition. This modification makes the steel easier to cut and shape, providing significant advantages for workshops and manufacturers looking to reduce costs and processing time.  

 

Key Benefits:  

- Faster Processing: Improved machinability reduces tool wear and boosts productivity.  

- Cost Savings: Shorter machining times and less tool wear lead to more economical solutions.

 

Why Does 1. Excel in Surface Finish?

On the other hand, 1. steel is widely recognized for its superior surface finish, making it the preferred choice for applications requiring high levels of polishing or detailed textures. Its chemical composition ensures cleaner and smoother surfaces, which are essential for high-quality molds.  

 

Key Advantages:

- Better Polishing Results: Ideal for molds that demand highly reflective or smooth surfaces.  

- Versatility: Used in detailed applications, such as molds for lenses or transparent plastic components.

 

When Should You Choose Each Steel?

Both materials are pre-hardened steels, typically delivered with a hardness range of 28 to 34 HRC. This feature eliminates, in most cases, the need for additional heat treatments, saving time and resources. However, the choice between the two should be guided by your project's specific needs.

- Choose 1. if:

  Your priority is steel that is easier to machine and allows for greater productivity in industrial environments.  

 

- Choose 1. if:

  Surface finish is critical for your project, such as molds for high-precision plastic parts.   

Durability and Performance

Both steels offer good dimensional stability and wear resistance. However, their chemical differences result in specific advantages. While 1. stands out for machining efficiency, 1. is better suited for molds that require superior aesthetic quality.  

 

Understanding these nuances helps mold manufacturers and steel distributors optimize their choices, ensuring both productivity and quality.

Both 1. steel and 1. steel are pre-hardened plastic mold steels whose hardness is evenly distributed on a large cross-section, and are mainly used to manufacture molds and tool parts. They have many similarities, so when choosing 1. material and 1. material, you should first understand the differences between them, so that you can choose a more suitable and better steel for the project that needs to be applied.

This article will discuss the main differences between 1. material and 1. material in terms of chemical composition, hardness, mechanical properties, heat treatment and application,etc.
