It blackens the steel and forms a 1μ oxide film on the surface to prevent rust. Additionally, it also aims to enhance aesthetics (visual beauty).
The chemical reaction of black dyeing forms a 1μ oxide film on the surface of steel products, enhancing their rust prevention capabilities. Since painting is a topcoat, it results in dimensional changes, but black dyeing penetrates the item itself, so the original dimensions of the item remain largely unchanged, making it suitable for items that require dimensional accuracy. It improves rust prevention (rust stopping) and aesthetics (visual beauty) of iron and steel products, and has the effect of reducing light reflection. Additionally, our company hand washes each item for black dyeing, especially for complex shapes like machine parts or shapes prone to drug accumulation, resulting in clean products that are less likely to retain chemicals. <Alternate names for black dyeing> Ferric oxide treatment, ferric oxide treatment, Fe304, alkaline coloring.

basic information
This is an item that has been blackened with dye. Iron is a cheap material that is inherently prone to rust, leading to the formation of red rust. Therefore, by applying a black dye treatment, we can prevent the occurrence of red rust. Due to a chemical reaction, a 1μ thick oxide film is formed on the surface, so the dimensions hardly change. This technology is very suitable for mechanical parts and screws where dimensional accuracy is required.
