Materials & Manufacturing‌
Railway wheelsets are precision-engineered components comprising high-strength alloy steel axles and premium forged/rolled steel wheels.

· ‌Wheels‌: Manufactured from grades like AAR-B, ER7, or CL65/CL70 steel using integral forging and vacuum degassing to ensure density and defect reduction‌14.

· ‌Axles‌: Made from alloy steels (e.g., 40Cr, 50Cr) or stainless steels (304L/316L), offering fatigue resistance and corrosion stability‌.

· ‌Assembly‌: Hydraulic press-fitting with interference fit, followed by ultrasonic testing to guarantee zero-defect alignment‌.
