1.3 DEFINITIONS
************************************************************************************************************************
Definitions listed below are from the Designer Handbook, Finishes for Stainless Steel by SSINA. To assist the specifier in selecting the proper finish the following commentaries are provided on each of these finishes.
No. 4: Satin brush finish achieved with 150 to 180 grit, fine directional polish. This is a common finish and is most often seen on washroom accessories. Another example is the metal cover plate on a 3.5 inch floppy disk.
No. 6: Hairline finish achieved with 80 to 140 grit, it has a well defined directional polish. The starting base substrate is a No. 4 that is then polished to provide a continuous long grain Ahairline@ look. This finish is popular with designers for an aesthetic look, and is popular with fabricators due to ease of matching the finish after welding operation.
No. 7: This mirror finish is not as commonly used. Although it is often called a mirror finish, this highly reflective finish does still have Ahazy@ polishing lines still visible. It is sometimes referred to as a Adirectional@ mirror finish or a Abrush@ mirror finish. If SSINA Atrue@ No. 8 finish is not clearly specified, this finish may be Asubstituted@ for the No. 8.
No. 8 or ATrue #8" by Hwa Yang
The most reflective mirror finish on the market and is usually what the designer is desiring when specifying ANo. 8 Mirror Finish@. All polishing grit lines from preliminary polishing operations are removed, and the look of a glass mirror is achieved.
This finish is sometimes referred to as Super 8, No. 9, Perfect No. 10, or even No. 12 mirror. Super #8 is a patented process by Hwa Yang Stainless. SSINA does not have published standards for any finish above No. 8.
CMP Super #8 Mirror by Hwa Yang
Chemical Mechanical Polished (CMP) Super #8 mirror finished sheets are guaranteed to be free from manufacturing defects. This is the ultimate in mirror polished stainless steel. It is available in single-sided or double -sided mirror polished sheets.
************************************************************************************************************************
A. SSINA Architectural Polished Stainless Steel Finishes:
1. No. 6 Finish: A dull satin finish having lower reflectivity than No. 4 finish. It is produced by Tampico brushing the No. 4 finish in a medium of abrasive and oil. It is used for architectural applications and ornamentation where a high luster is undesirable, and to contrast with brighter finishes.
2. No. 7 Finish: High degree of reflectivity produced by buffing finely ground surfaces, but not to the extent that existing grit lines are removed. Used chiefly for architectural and ornamental parts.
3. No. 8 Finish: The most reflective finish that is commonly produced on sheet, obtained by polishing with successively finer abrasives and buffing extensively with very fine buffing rouges. The surface is essentially free of grit lines from preliminary grinding operations. No. 8 finish is most widely used for architectural parts, small mirrors and reflectors, and for press plates.
B. Titanium Coloring: Titanium nitrite based physical vapor deposition (PVD) process for coloring stainless steel producing a finish plating that is highly resistant to abrasion, UV, and corrosion.
1.4 SUBMITTALS

************************************************************************************************************************
Edit following article to include finishes required for this project.
Polished Finishes:
Refer to definitions above. A true No. 8 finish must be specified, and samples submitted to ensure the end result. There is not a consistency in providing a No. 8 Finish. Hwa Yang has a patented finish for both True #8 and Super #8 which will ensure a correct No. 8 Finish. Single or double-sided polishing is available.
Typical sheet sizes are 4 feet by 8 feet and 4 feet by 10 feet. Custom size sheets and thicknesses can also be ordered from Hwa Yang Stainless, but they are subject to order minimums.
Titanium Colored Finishes:
Colors available from Hwa Yang Stainless include Gold, Brass, TI Gold, Rose Gold, Rose Copper, Bronze, Black, Charcoal. The colors are produced after the polishing process is complete.
Titanium coloring of stainless steel using this method does not require a protective lacquer coating over the finish. The achieved finish is highly resistant to abrasion, UV, and corrosion. There is a 30 year warranty available on this finish, including exterior applications. Consult finisher.
Chemically Etched Designs:
Hwa Yang Stainless has over 82 standard etched designs. Custom etching designs are available. The designs are produced after the polishing process is complete, and if titanium coloring is desired, the etching is produced before the coloring is complete. Therefore, you may have a chemically etched design on a polished sheet or you may have the chemically etched design on a polished and colored sheet.
Typical sheet size for acid etching is 4 feet by 8 feet. Consult with manufacturer for special size sheets.
