SBN30-Brake Drum
Excellent machined surface quality
Chipping occurred after 200 workpieces when using a competitor’s product, resulting in a deteriorated surface finish. In contrast, SBN30, with its excellent fracture resistance, showed no chipping and maintained a good surface finish, thereby contributing to improved quality.
