304 stainless screw how to solve the problem of electroplating easy to fall off?

In general, if it is to do screws, generally do surface treatment, some in order to increase the appearance of the beautiful, some in order to increase corrosion resistance and rust resistance. But for 304 stainless screw, some plating surface is easy to fall off, how to solve this?

304 stainless screw

304 stainless screw will be easy to fall off only when the surface treatment of electroplating environmental black zinc is done. This is because the adhesion of stainless steel material itself with the plating solution is not strong, so it will be easy to fall off. If the customer just for the black surface, then can be changed to high temperature blackening, electrophoresis can be made into black surface treatment; If it is to increase the screw anti-rust performance, can be changed to passivation, zinc nickel alloy, electrophoresis and other surface treatment.

But sometimes if the surface treatment of 304 stainless screw is changed, some customers will feel that the cost is higher, which is unacceptable to them. At this time, customers can consider changing the material to carbon steel, because the plating of the screws will not fall off easily, so that the cost of screws will be reduced.
