Mold steel plays an important role in the manufacturing industry, especially in industries such as automotive manufacturing, plastic products, electronics, and hardware products. The main characteristics of mold steel are high hardness, high wear resistance, high strength, and good corrosion resistance. According to different uses and working conditions, mold steel can be divided into cold work mold steel, hot work mold steel, plastic mold steel, and hot forging mold steel. In addition, mold steel also includes various types such as time hardening, corrosion resistance, and easy deformation to meet the needs of different mold manufacturing.

Mold steel can be used to manufacture molds such as cold stamping dies, hot forging dies, and die-casting dies. Mold is the main processing tool for manufacturing parts in industrial sectors such as mechanical manufacturing, radio instruments, motors, and electrical appliances. The quality of molds directly affects the quality of pressure processing technology, product accuracy and production cost. In addition to reasonable structural design and processing accuracy, the quality and service life of molds are mainly affected by mold materials and heat treatment.

1. High hardness: After overheating treatment, the hardness of the mold steel can reach HRC50 or above, making it have high wear resistance and impact resistance.
2. High toughness: Mold steel has a certain degree of toughness and can withstand deformation such as impact and bending, ensuring the accuracy and service life of the mold.
3. Good corrosion resistance: After surface treatment, the mold steel has good corrosion resistance, which can extend the service life of the mold.
4. Excellent processing performance: Mold steel can be processed by turning, milling, drilling, grinding, etc., making it easy to manufacture complex mold shapes and structures.

Different type of mould steel has different characteristics. The characteristics of common grades of mould steel as below.

D2 Steel

SAE D2 has great hardenability and wear resistance. After quenching and polishing, its corrosion resistance will be better. And its heat treatment deformation is small, is a good material for cold work mold with high precision and long life.

P20 Steel

It belongs to plastic mould steel. Due to the great machinability and other properties, it is widely used for plastic injection mold cavities and tooling and for die casting dies for zinc.

Mold Steel 718

It has great mechanical property and machinability. With sample processing technic, it is commonly used in the industry of mold.

H13 Steel

It has high hardenability and toughness and medium wearing resistance. And the heat treatment deformation is small. By the way, it can be used to make the fittings of the aircraft industry.
