  Advantages and applications of high carbon steel seamless pipes

  High carbon steel seamless pipes are seamless steel pipes made primarily from high carbon steel (typically 0.6%~1.7% carbon content). Due to their high strength, hardness, and excellent wear resistance, they play a crucial role in specific industrial applications. However, careful selection is required due to their low toughness and poor weldability. This article explores the advantages, typical applications, and precautions of high carbon steel seamless pipes.
