What is the mold material.

Mould steel is a pure steel material produced in accordance with the German DIN standard, which has relatively superior mechanical properties and good machinability in similar grades of steel, and is mainly used for the processing and production of hot work molds, among which the application of plastic molds is the most common. In addition, the pre-hardening treatment of the special finger hu of the steel makes it have a good hardness when it leaves the factory, which can reduce the heat treatment link in the processing and production of the normal mold and improve the economic benefits.

It belongs to 430 steel that changes its composition and becomes easy to cut.

Hello, and is the same material are void god is a plastic pre-hardened mold steel.

The chemical composition and steelmaking process of the two are the same. The difference lies in the difference in material and material hardness.

The meaning of 2738hhigh intensity is hard, which is higher than the hard letter.

Here's a brief rundown:

The difference is that the hardness of the material is different.

It is a German grade, and the corresponding Chinese grade is 40crmnnimo;

Mould steel is a steel material for die section excavation tools produced in accordance with the German DIN standard of slag burning, which has relatively superior mechanical properties and good machinability in similar grades of steel, and is mainly used for the processing and production of hot cracking molds, among which the application of plastic molds is the most common. In addition, the special pre-hardening treatment of the steel makes it have a good hardness when it leaves the factory, which can reduce the heat treatment links in the processing and production of normal molds and improve economic benefits.
