What should I do with the surface treatment of black stainless steel screws?

Stainless steel screws are well received by many companies because of their good rust resistance. However, some customers like to make the surface of stainless steel screws black, because they do not like the color of stainless steel, prefer black. So what about the surface treatment of black stainless steel screws?

When made of black stainless steel screws, there are several surface treatment options: electroplating, environmentally friendly black zinc, electrophoresis, high temperature blackening, vacuum black, etc. However, in these kinds of surface treatments, Shi Shi Tong screw manufacturers do not recommend the surface treatment of environmentally friendly black zinc, because the adhesion of this surface treatment to stainless steel is not high, which means that the black surface of the screw is easy to fall off.

If you are worried about the surface of the black stainless steel screws and cannot change the material, then do electrophoresis, high temperature blackening, etc. The surface can also be made black. However, these surface treatment costs are higher than those of environmentally friendly zinc. So see if you can accept this price, if you can’t accept it, suggest stainless steel or change the material. This cost will not be so high.
