It blackens the steel and forms a 1μ oxide film on the surface to prevent rust. Additionally, it also aims to improve 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 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 also reduces light reflection. Additionally, our company hand washes each item for black dyeing complex shapes, such as 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 (III) treatment, Fe304, alkaline coloring.
Inquire About This Product
basic information
This is a machine part that has been blackened. Since iron is inexpensive, it is originally a material that rusts easily and develops red rust. Therefore, by applying a blackening treatment, the occurrence of red rust is prevented. A 1μ thick oxide film is formed on the surface through a chemical reaction, so the dimensions hardly change. This technology is very suitable for machine parts and screws where dimensional accuracy is required.
