Problems in the domestic fast fixture material market

by:Top Talent     2020-05-21
The materials used for quick fixtures cover a wide range, from general carbon structural steel, alloy structural steel, carbon tool steel, alloy tool steel, high-speed tool steel, stainless steel, maraging steel to hard alloy, insoluble alloy , High-temperature alloys, non-ferrous metals, etc. can be used, which is mainly fixture steel belonging to alloy tool steel. With the development of China's fixture industry, higher new requirements have been put forward on the quantity, quality, variety and performance of fixture materials, and the fixture material market has also developed rapidly. China's rapid fixture material trial production lags behind the needs of the fixture industry, mainly in several aspects: ⑴, sales channels are not smooth. ⑵, there are many black round bars, flat steel, fine materials, pre-hardened materials and products, and few standard parts. About 80% of China's fixture steel market is black-skinned round bars. After users get the materials, they have to change their forging and restructuring. The material utilization rate is low and the production cycle is long. (3) There are many fixture steels of general quality, but few high-quality fixture steels. A considerable part of the fixture steels with high requirements require vacuum refining and electroslag remelting. Remelting to ensure the high purity, high density, and high isotropy of steel, and the share of fixture steel in China through electroslag remelting is very small.
