Carbon steel base material treated with high-temperature black oxide, resulting in a uniform matte black finish. The coating is dense with strong adhesion, offering low cost, discreet assembly, and moderate rust resistance and lubricity. Suitable for indoor general machinery, home appliances, furniture, transmission mechanisms, and other fastening applications where a low-profile appearance and no high corrosion resistance are required. Highly cost-effective.
