The disadvantage of domestic mold steel industry

The mold industry is a stable user in the iron and steel industry, and it is a major promoter of the upgrading of steel products. The upgrading of the mold industry is to a certain extent subject to the varieties, quality, and services of high-grade steel products. Because China's mold still has all kinds of inadequacies, so it should improve a lot.

In recent years, the demand for precision, large-scale, complex, and long-life molds has increased in the Chinese mold market. With the rebound of the global economy, the rapid development of mold industry, the mold steel industry this year can achieve higher growth, mold industry in 2012 will be in a stable development, is expected to have 15% ~ 18% growth, "Twelve During the period, China's mold output value may exceed 250 billion, so the total demand for steel products in the mold industry will continue to rise. This not only promoted the development of China's mold industry, but also provided the market demand for China's steel industry.

In the face of a huge market that has just emerged, Luo Baihui, the secretary-general of the International Association for Modeling, believes that the current domestic mold steel can not fully meet the needs of the domestic mold industry, mainly in the following aspects:

1, behind the die steel production process, poor quality steel products such as internal quality <br> <br> universal tool steel h13, d2, ld other varieties can reach the common domestic U.S. standard astma681 die steel, generally an international level, the basic Can meet the general mold users at home and abroad. However, high demands are placed on users of high-standard die steels.

2. Little new domestic mold steel varieties

In recent years, some well-known foreign mold steel production companies have developed many new mold steel products, such as high strength and toughness mold steel, dh13, dh53, flame quenching mold steel, powder metallurgy cold mold steel, etc. These high-performance mold steel has become the current Typical brand products for the international mold market. In contrast, there are few new high-performance mold steels made in China, and there are few new steel molds developed.

3, the specifications are not complete

For example, plastic mold steel, which accounts for 60% of the amount of mold steel, has only two steel grades in China's alloy tool steel standards, while the United States has seven steel grades and forms a complete series of steel products. Countries such as the United States, Japan, France, and Switzerland have formed series in cold work die steels and hot work die steels, and only hot work die steels have six fixed common types, which are less than that of home-made die steels.
