The invention relates to a nickel plating method for a superfine stainless steel wire, which is characterized in that the stainless steel wire is placed in an electroplating pool and is soaked in electroplating solution, the current density of the current for electroplating is 2-4A/d of square meter, the PH value of the electroplating solution is 3-5, and the temperature of the electroplating ,Stainless steel is an alloy of iron that is resistant to rusting and corrosion.It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen.
The key difference between these two metals is, Nickel is a pure chemical element in d-block with some unique properties whereas stainless steel is a metal alloy containing iron, Chromium, and Nickel. The composition of those three elements vary in stainless steel; nickel contributes the least amount of quantity in composition,Nickel slag abrasive grit is available in various grades and sizes and has a Moh's hardness ranging from 6.5 to 7; which provides improved cutting relative to conventional industrial and silica sand abrasives.
