The thickness of hard chrome plating falls in the range of 0.0008 inch =
eight ten thousandths of an inch (0.02032 mm) (two hundredths of a =
millimeter) to 0.0015 inch (0.0381mm) but regular chrome plating is =
typically far less than the hard plating spec 0.0318 mm / 0.0015 inch =
unless the deposit is specified to be tested by a quality specification =
and measured by a precision gauge at a number of points across the =
surface.
=20
For comparison to move thicker, food wrapper aluminum foil is about =
0.04mm or about 0.0016 inch and thicker depending on its specifications =
for use which is about the thickness of paint on your car.
=20
If you take a flake of chrome plating, it will have the thickness of =
both the copper layer and the chrome layer.
=20
Now look at 1.5 mm (standard metric is 1.519mm) (1000 times thicker than =
plating) is approximately 16 gauge steel thickness or ~0.0598 inch.
=20
I think the OE bumpers were most likely 0.1046 inch (2.657mm) or one =
tenth of an inch being 12-gauge mild steel because there was some belief =
in structural safety before crumple zones.
=20
304 stainless is much harder and more durable than mild steel of the =
same thickness, certainly when pressed or hammered into the shape of the =
Triumph bumper, so 16-gauge 304 stainless steel could be justified, but =
those bumpers are most likely not DOT rated either for say a 5mph =
=E2=80=9Cbumper=E2=80=9D accident test and I will bet they have some =
disclaimer in their fine print that the bumpers are for cosmetic or show =
use.

No, wrong!! They specifically state: "Grade 304".=20
OK, Grade 304 stainless steel 1.5 mm thick. Makes for very thin bumper. =
But it does have 3 layers of paint on the back side to protect the =
bumper.
=20
=20
That is NOT plating, that is the composition of the steel to an =
international forging composition
standard that sets the amount of nickel, chromium, molybdenum and other =
metals used in the forge.
=20
100% is not a grade, that is supporting the statement for 304 stainless =
which is the grade. =20
=20
Nowhere in their statement do they make any claim "plated" or stainless =
steel plated.
=20
They do state for marketing 100% stainless steel, and engineering =
standard for 304 grade.
=20
It is an engineering thang ...

Sorry Alex,

You may want to do some fact checking. There is no grade for "solid =
stainless steel".

I do not believe a stainless-steel plating exists for plating over=20
mild steel technology exists a of yet.
