What are the commonly used materials for die-casting mold steel?

In the manufacture of die-casting molds, the commonly used materials mainly include steel and alloy materials.

The following is a detailed introduction to the commonly used steel materials in die-casting molds:

(1) H13 steel: H13 steel is a hot working die steel with excellent heat resistance and wear resistance. It is usually used to manufacture high-temperature die-casting molds and is suitable for die-casting of high-temperature molten metals such as aluminum alloys and magnesium alloys. H13 steel has good hardness and toughness, can withstand high temperature and high pressure working environments, and has a long service life.

(2) P20 steel: P20 steel is a pre-hardened mold steel with good cutting performance and wear resistance. It is usually used to manufacture medium-temperature die-casting molds and is suitable for die-casting of medium-temperature molten metals such as aluminum alloys and zinc alloys. P20 steel has high hardness and strength, can meet the use requirements of the mold, and has a low production cost.

(3) 718 steel: 718 steel is a heat-resistant plastic mold steel with good heat resistance and wear resistance. It is usually used to make high-temperature die-casting molds, suitable for die-casting of high-temperature molten metals such as aluminum alloys and magnesium alloys. 718 steel has high hardness and toughness, can withstand high temperature and high pressure working environments, and has a long service life.

(4) NAK80 steel: NAK80 steel is a high-quality plastic mold steel with good cutting performance and wear resistance. It is usually used to make low-temperature die-casting molds, suitable for die-casting of low-temperature molten metals such as aluminum alloys and zinc alloys. NAK80 steel has high hardness and strength, can meet the use requirements of the mold, and has a low production cost.

(5) 8407 steel: 8407 steel is a high-hardness mold steel with good wear resistance and impact resistance. It is usually used to make medium-temperature die-casting molds, suitable for die-casting of medium-temperature molten metals such as aluminum alloys and zinc alloys. 8407 steel has high hardness and toughness, can meet the use requirements of the mold, and has a long service life.

In addition to the above commonly used steels, there are some special requirements for die-casting molds that can use alloy materials, such as high-speed steel, cemented carbide, etc. These materials have higher hardness and wear resistance, and are suitable for special die-casting processes and material requirements.

In summary, the commonly used steel materials in die-casting molds include H13 steel, P20 steel, 718 steel, NAK80 steel, and 8407 steel. The selection of suitable materials depends on the die-casting process, metal materials, and mold use requirements. In practical applications, it is necessary to comprehensively consider factors such as material hardness, toughness, wear resistance, heat resistance, and cost to ensure the stability, precision, and durability of the mold.
