Suface treatment comparison:
The black oxide type is cost-effective and can resist corrosion if protective oil is applied regularly.
If it is used in a high-humidity environment or requires less maintenance, it is recommended to use the low-temperature black chrome type.
| Specification | Black Oxide | Low-Temperature Black Chrome |
| Method | Chemical conversion on steel surface forming black oxide layer | Electroplating black chrome at low temperature, usually with Ni underlayer. |
| Surface Quality | Matte black, prone to fading with abrasion. | Deep black, smooth, durable color, high aesthetics. |
| Coating Thickness | Very thin, ~0.5–1.5 μm, almost no dimensional change. | 0.3–2 μm, thicker if Ni underlayer is applied. |
| Corrosion Resistance | Moderate, depends on oil layer; not suitable for long-term outdoor use. | Very high, withstands humid/salty environments, long coating life. |
| Advantages | Low cost, fast, no dimensional change, easy to reprocess. | Superior corrosion resistance, hard, durable color, high aesthetics. |
| Disadvantages | Poor corrosion resistance without maintenance, easy fading. | Complex process, higher cost. |
