There are various types of steel used in molds, including carbon tool steel, alloy tool steel, high-speed tool steel, and hard alloy steel.

The selection of suitable steel depends on the working conditions, material requirements, and production needs of the mold.

Mold steel is an important material in mold manufacturing, and its types and properties directly affect the quality and service life of molds.

Below, we will provide a detailed introduction to several common mold steels and their applications.

1、 Carbon tool steel

Carbon tool steel is one of the most commonly used steels in mold manufacturing.

It has moderate strength, good toughness, and wear resistance, and is suitable for manufacturing some low precision molds, such as stamping molds, plastic molds, etc.

The main advantages of carbon tool steel are low cost and easy processing, but its wear resistance and corrosion resistance are poor.

2、 Alloy tool steel

Alloy tool steel is made by adding a small amount of alloying elements to carbon tool steel to improve its performance.

Alloy tool steel has high strength and hardness, good wear resistance and corrosion resistance,

 and is suitable for manufacturing molds with medium precision and complexity, such as plastic injection molds, die-casting molds, etc.

3、 High speed tool steel

High speed tool steel is a type of mold steel with high hardness, wear resistance, and high thermal stability.

It is suitable for manufacturing high-speed cutting and heavy-duty molds, such as punching dies, cutting dies, etc.

The main advantages of high-speed tool steel are good wear resistance and long service life, but its cost is high and the processing difficulty is relatively high.

4、 Hard alloy steel

Hard alloy steel is a composite material composed of hard phases and metallic phases, which has high hardness and wear resistance.

It is suitable for manufacturing high-precision, high load, and high-speed cutting molds, such as precision punching molds, powder metallurgy molds, etc.

The main advantages of hard alloy steel are good wear resistance and long service life, but it is difficult to process and costly.

In short, when choosing mold steel, the appropriate steel should be selected based on the working conditions, material requirements, and production needs of the mold.

Meanwhile, attention should also be paid to the processing and heat treatment properties of the steel to ensure the quality and production efficiency of the mold.
