It blackens the steel and forms a 1μ oxide coating on the surface to prevent rust. Additionally, it also enhances aesthetics (visual beauty).
The chemical reaction of black dyeing forms a 1μ oxide film on the surface of steel products, enhancing their rust resistance. Since painting is a topcoat, it causes dimensional changes, but black dyeing penetrates the item itself, resulting in minimal changes to the original dimensions, 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 also reduces light reflection. Additionally, our company hand washes each item for black dyeing, especially for complex shapes like machine parts or items prone to drug accumulation, resulting in clean products that are less likely to retain chemicals. <Other names for black dyeing> Ferric oxide treatment, ferric oxide treatment, Fe304, alkaline coloring.
Inquire About This Product
basic information
This is a product that has been blackened for machine parts. Iron is inexpensive but is originally a material that rusts easily, leading to the formation of red rust. Therefore, by applying a blackening treatment, we can prevent the occurrence of red rust. Since a 1μ thick oxide film is formed on the surface through a chemical reaction, the dimensions hardly change. This technology is very suitable for machine parts and screws where dimensional accuracy is required.
