AMS-QQ-N-290A

There is a nickel finish for almost any need. Nickel can be deposited soft or hard – dull or bright, depending on process used and conditions employed in plating. Thus, hardness can range from 150-500 Vickers. Can be similar to stainless steel in color, or can be a dull grey or light grey (almost white) color. Corrosion resistance is a function of thickness. All steel parts having a hardness of Rc-40 or greater require a post bake at 375° ±25°F.
