Properties and characteristics of imported tungsten steel
Properties of imported tungsten steel plates
1, raw material purity of more than 99.95%, impurity content is very little, the physical properties of the plate is more stable;
2. Spray drying technology is adopted to protect the materials under the condition of full seal with high purity nitrogen, which effectively reduces the possibility of oxygenation in the preparation process of the mixture. The purity is better and the materials are not easy to dirty;
3, uniform plate density: the use of 300Mpa isostatic press pressing, effectively eliminate the production of pressing defects, plate blank density is more uniform;
4, the density of the plate is good, strength and hardness indicators are very good: the use of low pressure sintering technology, so that the internal pores of the plate can be effectively eliminated, the quality is more stable.
5, the use of cryogenic treatment technology, so that the internal metallographic structure of the plate is improved, the internal stress can also be greatly eliminated, avoid the plate in the process of cutting forming cracks;
The application scope of imported tungsten steel plate
1, suitable for making cast iron roll and high nickel chromium roll dressing molding tool;
2, suitable for the production of discharge plate, stamping die, punch, electronic progressive die and other stamping die.
