1.What is YG6 Tungsten Steel?<\/p>\n
YG6 tungsten steel is a tungsten-cobalt hard alloy, a medium-grain tungsten-cobalt alloy composed of tungsten carbide (WC) powder and cobalt (Co) powder, with WC powder accounting for 94% and cobalt powder for 6%.<\/p>\n
2. Features of YG6 Tungsten Steel<\/p>\n
It has a density of 14.6-15.0 g\/cm\u00b3, hardness of approximately 89.5 HRA, bending strength of about 1380 N\/mm\u00b2, and impact toughness of 2.6 \u03c3K\/(J\/cm), offering good usability strength, impact toughness, wear resistance, and corrosion resistance.<\/p>\n

3. Production Process of YG6 Tungsten Steel<\/p>\n
The process includes: batching (tungsten carbide and cobalt powders) \u2192 wet milling \u2192 mixing with binder, drying, and granulation \u2192 mixed granules \u2192 forming \u2192 sintering \u2192 tungsten-cobalt hard alloy. The sintering process is divided into four basic stages: removal of forming agents and pre-sintering phase, solid-phase sintering phase (800\u00b0C to eutectic temperature), liquid-phase sintering phase (eutectic temperature to sintering temperature), and cooling phase (sintering temperature to room temperature).<\/p>\n
4. Applications of YG6 Tungsten Steel<\/p>\n
It is suitable for the finishing and semi-finishing of cast iron, non-ferrous metals and their alloys, and non-metallic materials. For example, it is applicable under high-stress conditions for drawing steel, non-ferrous metals, and alloy rods with diameters less than 20 mm, as well as for drawing tubes with diameters under 10 mm; it is also suitable for manufacturing cold heading, cold punching, and cold pressing molds for standard parts and bearings.<\/p>\n

5. Processing Precautions for YG6 Tungsten Steel<\/p>\n
Due to its high brittleness, it is prone to cracking and chipping under impact or excessive processing loads.<\/p>\n
The processed surface after cutting or grinding is very smooth with sharp edges; please handle and use with care for safety.<\/p>\n
The surface after electrical discharge machining is most susceptible to cracking and chipping; adjust the processing procedure according to the product’s usage conditions.<\/p>\n
Cracking often occurs during wire cutting; please confirm the processed surface is defect-free before proceeding to the next step.<\/p>\n","protected":false},"excerpt":{"rendered":"
