Tungsten steel: tungsten steel, cemented carbide, tungsten steel manufacturers, tungsten steel tools, tungsten steel molds, tungsten steel plates, tungsten steel round bars, tungsten steel round molds, YG15, YG8, YG20, YL80, YL90 tungsten-cobalt hard The main components of the alloy are tungsten carbide (WC) and binder cobalt (Co).
The grade is composed of "YG" (the initials of the Chinese pinyin of "hard and cobalt") and the percentage of the average cobalt content.
For example: YG8, which means the average WCo=8%, and the rest is tungsten-cobalt cemented carbide of tungsten carbide.
YG8 cemented carbide is known as Wanjin Oil, which is a very common cemented carbide grade. The production process mainly includes: ingredients → full mixing → crushing → drying → adding forming agent after sieving → re-drying → sieving to obtain a mixture → granulating and pressing the mixture → forming → low pressure sintering → sintered blank → inspection ( Non-destructive ultrasonic flaw detection)→Rough dimensional accuracy inspection.
Performance and purpose: good strength and impact toughness, good wear resistance. It is suitable for drawing steel, non-ferrous metal and alloy bars with a diameter of less than 20 mm under high stress conditions, and also suitable for drawing pipes with a diameter of less than 10 mm. It is suitable for the production of cold heading, cold punching and cold pressing molds for standard parts, bearings, etc.
Tungsten steel sheet
The main physical parameters of YG8 cemented carbide are as follows:
1. Density g/cm3:14.6.
2. Hardness: 89.5.0HRA.
3. Bending strength: 2320MPa.
4. Elastic modulus: 510GPa.
5. Thermal expansion coefficient 10-6/OC: 5.1.
6. Co content: 8.0%.
7. Grain size: 1.0um.
YG8 cemented carbide is a commonly used brand of cutting tools. It is the most widely used brand for custom-made cemented carbide blades in mechanical production and processing. Of course, YG8 cemented carbide is also selected for wear-resistant molds and parts for its good wear resistance. YG8 cemented carbide products have the characteristics of high hardness, high wear resistance, high red hardness, good weldability, etc., and excellent overall performance. They are suitable for processing solid wood, density board, gray cast iron, chilled cast iron, stainless steel and other materials.
For example: YG6 Chemical composition: WC: 94 Co: 6% Mechanical properties Density (g/cm3): 14.6-15.05 "Hardness (HRA): ≥ 89.5" Bending strength (N/mm2): ≥ 1670 "Impact toughness σK/(J/ cm): 2.6
