Stainless steel screws surface needs to be done to those handled?

stainless steel screwSurface treatment: Most stainless steel self-tapping screws of the outer coating system use galvanized or zinc coated. Cadmium plating because of its high cost and toxicity thus use very little, if appearance is very important, able to pick nickel or chrome.

Disposal can look attack two questions:

One is the appearance of the disposal will not only increase the scale (for example, reduce pores, etc.) and does not look the same disposition will affect the contact between the torque, tighten the extent, intensity, so do the experiments to be scored by zinc plating cadmium phosphate or disposal do not the same as the rules. When test drilling diameter applies attack, the use of stainless steel screws are necessary to screw the same look disposal.

Second, high hardness, small-scale stainless steel self-tapping screws often due to hydrogen embrittlement resulting in the use of defeat. Stainless steel self-tapping screws in order to hack into iron, carburizing shall not be disposed of. After carburizing disposal will attack high hardness and high carbon content, when this situation do plating or pickling will explode when disposed of hydrogen embrittlement.

Normative approach advocated elimination of hydrogen embrittlement is:

1, after pickling or electroplating baking purposes of disposal within one hour.

2, a temperature of 375 ~ 425 oF (190 ~ 220 oC). At least four hours time.
