Blackening work piece at room temperature, easy operation, low cost and stable process
The working principle is oxidation and phosphating, which results in a better blackening effect.
Benefits of the process include the addition of mild corrosion resistance, improves aesthetic appearance and the minimising of light reflection. Maximal corrosion resistance can be achieved when the oxide is impregnated with oil or wax.
The process essentially involves embedding a pigment into the fixing which unlike paint or plating, does not alter the precise dimensions or surface texture.
The vast majority of stainless steel fasteners can be chemically blacked upon request.
