1、 Alloy steel is a type of steel material that changes its properties and characteristics by adding alloying elements to ordinary steel. The alloying elements of alloy steel can include noodles, molybdenum, nickel, vanadium, manganese, etc. By combining different alloying elements, alloy steel can have different properties, such as wear resistance, corrosion resistance, high-temperature strength, etc.

2、 Performance characteristics of alloy steel

High strength: Alloy steel can significantly improve its strength by adding alloying elements. The presence of alloying elements can alter the crystal structure of steel, giving it a more uniform structure and better mechanical properties. This allows alloy steel to withstand greater forces and pressures in high-pressure and high-temperature environments.

Corrosion resistance: Some alloying elements in alloy steel, such as noodles and nickel, can form a dense oxide layer, which plays a role in resisting oxidation and corrosion. This makes alloy steel have excellent corrosion resistance in harsh environments, which can extend its service life.

Wear resistance: Alloy steel has excellent wear resistance and can resist the effects of friction, wear, and cutting forces. This enables alloy steel to withstand significant impacts and wear during mold manufacturing, while maintaining stable dimensions and shapes

High temperature strength: Some alloy steels can significantly improve their high temperature strength by adding alloying elements such as molybdenum and vanadium. This allows alloy steels to maintain high strength and hardness in high-temperature environments, and are less prone to deformation and melting, making them suitable for high-temperature working environments.

Workability: Although alloy steel has high hardness and strength, it still has good machinability. Alloy steel can adjust its structure and properties through appropriate heating, forging, and quenching processes to meet the needs of different applications.

3、 Application fields of alloy steel

Mold manufacturing: Alloy steel is widely used in the mold manufacturing industry due to its high hardness, high wear resistance, and stable dimensional performance. Molds made of alloy steel can be used for plastic injection, die casting, stamping, forging and other processes to improve the service life and production efficiency of the molds.

Tool manufacturing: Tools made of alloy steel have high hardness and wear resistance, and are widely used in metal processing, cutting, drilling and other processes. Alloy steel tools can improve machining quality and efficiency, reduce tool wear, and
