Application fields:
Wear resistant materials used in industries such as petroleum, mining, steel mills, power plants, etc. for material conveying equipment or liquid flow on the surface of pipelines. Their main function is to effectively resist the impact of materials passing through the pipeline wall
Product Features:
Dry pressing and high-temperature firing result in a Rockwell hardness of HR80-90, second only to diamond.
