Talking about the problems in the domestic mold material market

The materials used in the mold include a wide range, from general carbon structural steels, alloy structural steels, carbon tool steels, alloy tool steels, high speed tool steels, stainless steels, maraging steels to hard alloys, insoluble alloys, High-temperature alloys, non-ferrous metals, etc. can all be used, among which are die steels belonging to alloy tool steels. With the development of our country's mold industry, we have put forward higher requirements for the quantity, quality, variety and performance of mold materials, and the mold material market has also been rapidly developed.

The trial production of mold materials in China lags behind the needs of the mold industry, mainly in several aspects:

(1) The sales channels are not smooth.

(2) There are many black round bars, flat steel, fine materials, pre-hardened materials and products, and fewer standard parts. About 80% of China's die steel market is black bar. After users get the material, they must change their own forging system. The material utilization rate is low and the production cycle is long. It can not meet the needs of the mold manufacturing industry.

(3) There are many mold steels of the general quality, and there are few high-quality mold steels. A considerable part of the required mold steels are subject to vacuum refining and electroslag remelting. Some foreign companies require mold steels with a section greater than 150 mm to undergo electroslag. Remelting to ensure high purity, high density, and high tropism of steel products, while China's share of die steel through electroslag remelting is small.
