Mold Steel - Developmental Status of Mold Steel Technology in Our Country, Comparing with Development of Mold Steel Overseas


Mold is the cornerstone of industrial development, the manufacturing industry in various countries in the world in order to reduce product costs, improve product quality

Volume and Productivity  Improved Material Utilization  Energy Saving  Wide range of die forming processes

For the traditional cutting process. According to the International Mold and Metal & Plastic Industry Supplier Association Luo Baihui referral

Shao  Currently, there are about 60% ~ 80% of the products in machinery manufacturing, electronics industry, light industry and other industrial sectors

Molded with a mold. A lot of product quality, dimensional accuracy, surface roughness, replacement speed and product

The cost, largely depends on the quality of the mold, service life and manufacturing cycle. As the main mold material

Material mold steel is the basis of mold manufacturing  With the rapid development of the mold industry, the number of mold steel,

Quality, variety, specifications, performance and other aspects, continue to put forward higher and newer requirements. In recent years 

Mold steel production at home and abroad, production technology, technology and equipment, quality, variety, etc. have made more rapid

Rapid development.

    1, the development of steel mold steel

    Mold steel production in China already ranked the forefront of the world. Mold steel production has increased rapidly in the past two decades

Leading to other steel  mold steel production accounts for about 80% of alloy tool steel. With mold working conditions

Increasingly harsh  countries in the original cold-work die steel, hot work die steel and plastic mold steel on the basis of three categories 

Have also developed a lot of new steel to meet the new requirements.

    In cold work die steel, the material developed 

    (1) high toughness, high wear resistance of the die steel C, C content of these steels is lower than the traditional Crl2 die steel 

Increased the number of Mo, V alloy , its wear resistance is better than Crl2MolVl steel toughness and anti-temper softening capacity then

Higher than Crl2 such as the United States vanadium alloy steel company early published VascoDie (8Cr8M02V2Si), Japan Datong

Special steel company's DC53 (CrSM02VSi)  developed in China there are 7CrTM02V2Si (LD steel),

9CrW3M02V2 (GM steel), etc.  separately for cold extrusion dies  cold stamping dies and high strength bolts rolling dies

With.

    (2) Low-alloy air-quenched micro-deformed steel This type of steel is characterized by low alloy content (≤ 5%), hardenability, hardened

Good Φ100mm workpiece can be air-cooled hardened, small deformation, good processability  Mainly used in the manufacture of fine

Close complex mold. Such as the United States ASTM standard steel A4 (Mn2CrM-o), A6 (7Mn2CrMo), Japan Datong special

Special Steel Company's G04. China's own research and development of Gr2Mn2SiWMoV and 8Cr2MnMoWVS and other steel also belong to

Low-alloy air-quenched micro-deformed steel  after a steel number also have excellent machinability.

    (3) flame quenching die steel This type of steel is characterized by a wide range of quenching temperature, good hardenability. Because of the flame

Local quenching process is simple, in order to shorten the mold manufacturing cycle, reduce manufacturing costs and other characteristics have been widely

Used in the manufacture of cutting, blanking, stamping, cold forging and other cold-working mold  especially large-scale mold inserts such as Dongfeng

Car companies using China's development of 7CrSiMiMoV flame hardened steel manufacturing car cover insert punch block

Oral material  made good use of the results. The steel of this type of steel is Aichi Co., Ltd. of Japan

SX5 (Cr8MoV) Datong Special Steel G05 Japan's Hitachi Metals HMDl.
