there are no laws that define what "triple chrome plating" actually means - just that there are a total of 3 layers of any kind of plating - "triple plate" could be the cheapest version: 1 coat of copper/ 1 coat of nickel/ 1 coat of chrome [always very thin]
normal high quality chroming has the copper and 2 coats of nickel [a semi-bright nickel coat followed by a bright nickel coat], and that's the usual expensive type - I'd expect that "triple nickel" chrome would have had 3 layers of nickel, which is the real corrosion prevention
