Can stainless steel screws be made into a black surface?

Generally, when producing screws, some customers will ask about the surface color of screws, because this will increase the beauty of their products. So, can the stainless steel screws make the black surface?

Stainless steel screws can be made into black surfaces. If you want to make a black surface, it can be achieved by several surface treatments, such as electrophoresis black, environmental black zinc, high temperature black, vacuum black, etc. Electrophoretic black, environmental-friendly black zinc and vacuum black tend to be more inky. Although they are both inky, their colors are still different. Electrophoretic black and environmental-friendly black zinc tend to be bright black, while vacuum black tends to be dumb black. The blackness of the heat is more like the blackness of the light.

In terms of price, vacuum black and electrophoretic black are very expensive, followed by high-temperature blackening, and finally, environmentally friendly black zinc, which reduces in turn in price. In terms of the surface durability, the effect of environmental protection black zinc is very poor, because the surface adhesion is very poor with the stainless steel surface, very easy to fall off; Electrophoretic black, high-temperature blackening, and vacuum black are all ok and are less likely to fall off.

What kind of surface treatment is needed to make the surface of stainless steel screws black, but also need to see their specific needs.
