Silver180® is a pre-coated steel sheet that can be used in a wide variety of �elds and applications due to its following features.
2. Superior scratch resistanceSilver180TM 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-friendlySilver180TM can be called a resource - saving product since it lasts long and provides excellent corrosion resistance withrelatively 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 resistanceIn 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

Quality Characteristics
According to results of exposure tests conducted over a period of approximately seven years, Silver180TM is four times as corrosion resistant 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 scratchingwas 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 conductivityand 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.
