According to the publicly available information on the site, Kaiyue commonly uses high-strength alloy steel materials such as 55SiMnMo, 35CrMo, and 42CrMo, and will optimize the structure and heat treatment according to different working conditions.

In terms of manufacturing processes, key capabilities include stable connection processes for dissimilar materials, as well as standardized processing and re-inspection of threads, joints, and critical dimensions. Our goal is not simply to produce products, but to make drilling tools more suitable for continuous field operations in terms of strength, interchangeability, and wear resistance.
