Class 1: for decorative application on steel,zinc, copper.

Class 2: .003" thick - or as specified on drawing.

Coating for steel, copper, copper alloys, zinc and zinc alloys. Nickel can be deposited soft or hard, dull or bright, depending upon process used and conditions employed in plating. Thus hardness can range from 150-1500 Vickers. Can be similar in color to stainless steel, or can be a dull gray or light gray (almost white). Corrosion resistance is a function of thickness. Has a low coefficient of thermal expansion. is magnetic. All steel parts having hardness of RC-40 or greater require a post bake at 375F for 3hours. All steel parts having tensile strength of 220,000+ shall not be nickel plated without specific approval of buyer. steel and zinc alloys shall have copper underplate .0002" min. copper alloys containing 40%+ zinc shall have copper underplate .0003" min.
