Tungsten carbide needles have good chemical stability. Tungsten is an inert metal that does not react with most chemicals at room temperature. Therefore, tungsten carbide needles are not susceptible to chemical corrosion and can be used in a variety of chemical environments, such as acidic or alkaline solutions, corrosive gases, etc. However, if the tungsten carbide needle is in contact with a strong oxidizing agent such as oxygen or halogen, an oxidation reaction will occur. In addition, under the conditions of high temperature and high pressure, tungsten carbide needles may undergo chemical reactions or corrosion.
