2. Silver180®is a pre-coated steel sheet that can be used in a wide variety of fields and applications due to its following features.
2. Superior scratch resistance
Silver180TM
has better scratch resistance than ordinary hot dip galvanized steel sheet.
3. Replacement for post hot dip galvanized products (surface-treated in their final shapes)
With its attribute to withstand severely corrosive environments, Silver180TM
can replace post hot dip galvanized products
and thus enable customers to streamline manufacturing processes.
4. Resource-saving and Environment-friendly
Silver180TM
can be called a resource - saving product since it lasts long and provides excellent corrosion resistance with
relatively light coating.
Silver180TM
can also be called an environment-friendly product since it satisfies requirements of such environmental
regulations as RoHS and ELV *.
1. Superior corrosion resistance
In corrosion resistance ¤ , Silver180TM
is 10 to 20 times tougher than galvanized steel sheet and 5 to 8 times better than
Zinc Aluminum alloy coated steel sheet when subjected to accelerated testing. ¤ estimated by salt spray test
＊Please specify "chromium-free" treatment

Quality Characteristics
Accordingtoresultsofexposuretestsconductedoveraperiodofapproximatelysevenyears,Silver180TM
isfourtimesascorrosionresistant
as galvanized steel sheet. Since corrosion mass loss of zinc-aluminum coated steel sheet tends to lessen over time, the superiority of
Silver180TM
in this respect is likely to become more pronounced in subsequent years.

Silver180TM has harder coating layer than hot dip galvanized steel sheet or hot dip 55%aluminum-zinc alloy coated steel sheet, which
gives it better scratch resistance and allows it to be used in applications that are subject to scratching and repeated friction during
processing.
A sapphire testing
needle having a tip radius of 0.05mm was pressed vertically
against the test piece with a force of 0.0196-0.196 N (2-20gf).
The needle scratched across the test piece for a distance of
20mm. After the surface was visually examined for any
scratching, and the minimum load that produced scratching
was taken as the scratching load.

Quality Characteristics
With its inorganic after-treatment involving no chromium
at all, this material is gentle on the environment.
The inorganic special treatment chromium-free layer has
low electrical resistance and excellent surface conductivity.
This gives Silver180TM the same electrical conductivity
and suitability for spot welding as conventional materials.
With the chromium-free organic film, there is no
elution of chromium (Vl) compound and hence
chromium-free organic special treatment products are
environment-friendly.
Enhanced scratch resistance can be attained at roll
forming and other processes.
The special film provides better corrosion resistance
both on flat and processed parts.

testing laboratory and are based on actual
exposure time.
Nothing works better longer.
In typical formulations [see shaded areas],
Hyper180TM

fluorine levels than FEVE-based coatings,
resulting in greater resiliency, color and gloss
