How To Choose Different Grades Of Tungsten Steel?
Many buyers encounter premature failure of carbide parts. The key reason is improper grade selection.
Tungsten carbide performance is adjusted by cobalt content and WC grain size:
- Higher cobalt: better toughness & impact resistance, lower hardness, suitable for mining picks and crushing teeth.
- Lower cobalt: higher hardness & wear resistance, less toughness, ideal for wear plates and cutting blades.
- Fine grain carbide: balanced hardness and toughness for precision cutting tools.Rule of thumb: high impact → high cobalt grade; abrasive wear with low impact → low cobalt fine grain grade.Hebei Zhongci Cemented Carbide Mould Co., Ltd. provides grade recommendation based on working conditions, material hardness, impact and temperature to avoid early part failure.
