What is the resistivity of the yg13 cemented carbide?
Three, technical parameters of YG13 tungsten steel1, WC and other alloy composition content%:87.2 and CO content%:13.3 density g/cm3:14.2.4 hardness HRA:90.5.5 、 grain size um:0.6 ultra-fine grain alloy.6. Flexural strength MPa:4000.7 thermal expansion coefficient 10-6/0C:5.8.8. Modulus of elasticity GPa:460.
Two, production processProportioning, mixing, crushing, drying, fully add sifted molding agent, then drying and sieving to prepare a mixture, pressing, mixing and granulating (Germany imported vacuum pressure sintering furnace), low pressure sintering and sintering the blank test after (nondestructive ultrasonic inspection), blank size accuracy test.
A brief introduction to YG13, tungsten steelYG13 is a kind of tungsten steel tungsten steel mold suitable for production of complex shape of the tungsten carbide, which is up to 4000MPa to its bending strength impact resistance performance is excellent, especially YG13 tungsten steel with moderate hardness, low pressure sintering is made of fine grain 0.6um alloy powder with high strength, good abrasion resistance by the large number of customers die trial, recognized by all say the same thing it is indeed a high ratio of tungsten steel mold materials, especially suitable for the production of powder pressing mould.
Four, YG13 tungsten steel product featuresYG13 ultrafine particles and by using tungsten alloy in low pressure sintering, uniform grain distribution, good compactness, no pore free porosity and uniform microstructure and excellent wear resistance, 90.5HRA hardness, flexural strength up to 4000MPa and have high wear resistance, comparable to the quality of imported tungsten steel material, some performance parameters are better than similar imported tungsten steel material.
