Specialty materials and new grade customization
For components that cannot be met by existing standard grades, we work with steel mills to design chemical compositions, smelting routes, and delivery conditions, and validate import substitution or dedicated materials through small‑batch trials.
Project materials include 41CrS4, 10B38, 16MnCr5, 10B21M, and 34CrNiMo6, among others; some special projects can begin with trials of approximately 200 kg, with applicability confirmed based on mill scheduling and the technical agreement.
