What are the brands of China's mold steel

As an important material in industrial production, the quality and performance of die steel directly affect the accuracy, strength and life of the product. In recent years, with the vigorous development of China's manufacturing industry, the demand for mold steel is also growing. So, what are the brands of die steel in China? What are their characteristics and advantages? Today, we will conduct a deep interpretation from the brand, performance, application and other aspects of domestic mold steel.

First, the brand and characteristics of domestic mold steel

1. Cr12MoV

Cr12MoV is one of the most common grades of die steel in China, its main components are carbon (C) 1.15%-1.25%, silicon (Si) 0.15%-0.35%, manganese (Mn) 0.40%-0.60%, molybdenum (Mo) 0.15%-0.30%, vanadium (V) 0.07%-0.12%. Cr12MoV has high hardness, strength and wear resistance, and is suitable for manufacturing various cold work dies, such as punches, blanking dies, cold heading dies, etc.

2. Cr12

Cr12 is a traditional high-carbon and high-chromium die steel in China, its main components are carbon (C) 1.10%-1.30%, silicon (Si) 0.15%-0.30%, manganese (Mn) 0.30%-0.60%, chromium (Cr) 11.00%-13.00%. Cr12 has good wear resistance and heat resistance, which is suitable for the manufacture of hot working dies, such as hot heading dies and hot extrusion dies.

3. 3Cr2Mo

3Cr2Mo is a commonly used alloy structural steel in China, its main components are carbon (C) 0.30%-0.40%, silicon (Si) 0.15%-0.35%, manganese (Mn) 0.60%-1.00%, chromium (Cr) 1.30%-1.80%, molybdenum (Mo) 0.20%-0.30%. 3Cr2Mo has high strength, toughness and wear resistance, and is suitable for manufacturing large, complex and stressed molds.

4. 5CrNiMo

5CrNiMo is a new type of high performance die steel in China. Its main components are carbon (C) 0.45%-0.55%, silicon (Si) 0.15%-0.35%, manganese (Mn) 0.60%-1.00%, chromium (Cr) 4.80%-5.50%, nickel (Ni) 0.70%-1.00%, carbon (C) 0.45%-0.55%, Silicon (Si) 0.15%-0.35%, manganese (Mn) 0.60%-1.00%, Chromium (Cr) 4.80%-5.50%, nickel (Ni) 0.70%-1.00%. Molybdenum (Mo) 0.15%-0.30%. 5CrNiMo has high strength, toughness and wear resistance, and has good thermal fatigue resistance, which is suitable for manufacturing large, complex and high-strength molds.

Second, domestic mold steel application cases

1. Automobile manufacturing

In the field of automobile manufacturing, the demand for mold steel is huge. Taking the stamping die as an example, the various parts of the car body need to be stamped. At this time, Cr12MoV, Cr12 and other high-performance mold steels come in handy. They guarantee the hardness and wear resistance of the punch and improve production efficiency.

2. Electronics industry

In the manufacturing process of electronic products, precision and quality are crucial. 3Cr2Mo, 5CrNiMo and other high-strength and high-toughness mold steels can meet the high requirements of the electronics industry for molds and ensure product quality.

Iii. Summary

In general, China's mold steel grades are many, each has its own characteristics. From Cr12MoV to Cr12, to 3Cr2Mo, 5CrNiMo, these die steels have a wide range of applications in various fields. At the same time, with the continuous development of China's iron and steel industry, domestic mold steel has gradually been in line with international standards in performance and quality, and even surpassed in some aspects. It can be said that the rise of domestic mold steel has become more and more broad.
