Type 304/304L Stainless Steel is the modern evolution of the original “18-8” austenitic stainless steel. It is an economical and versatile corrosion resistant stainless steel suitable for a wide range of general purpose applications.

Yieh United Co. Stocks over 25 grades of polished stainless steel sheet in a variety of finishes, including HL, #4 Brush, and #8 Mirror finish. We also can supply specialty finish to satisfy your exact requirements including polishing both sides of the sheets, long grain finishes, non-directional stainless steel sheet finishes, #6 finish, #7 finish or per customer requests.

REASONS TO CHOOSE 304/L POLISHED STAINLESS STEEL SHEET/PLATE
1. Raw Material
Our coil is originated from Taiwan, Krupp, Columnbia, Baosteel, TISCO, and other major steel production of high quality stainless steel. If coil is not from a good standard factory, the coils surface may have some problems, especially for the edge. They are not easily leveled and processed, after processing, there will be some vertical strips which make the surface not expected. Here is an example to show the bad finished surface is due to the material origin.

Note: these white strips cannot be removed by polishing.

2.Sandbelt
In the processing, sandbelt working time is a key factor for controlling the surface quality. If the sandbelt is new, the polished lines will be very rough and thick, and have less reflective effect.After the sandbelt has been used for a long time depending on the quality of the sandbelt,the polished strips maybe too shallow,which cannot reach the expected effect.

3.Film
After the surface processing, choosing the PVC film will have much influence on afterwards application. We have several kinds of film to be chosen, and they are suitable for different application. The film not only serves as a protection but also affect the afterwards processing.

>>Laser film
Laser film is considered to be one of the best film. The thickness is at least 10c. Laser film normally has higher melting degree than other film, which will not be melted and sticked on the surface after heat treatment. Here is an example of normal film after heat treatment.(Please confirm the downstream processing, and then decide which film is to be applied.)

>>Black and white film imported from other countries except China

This kind of film cannot undertake high temperature treatment, but it is relatively thicker and more sticky than Chinese Origin film. It can be used in most mechanical process and have a good performance.

>>Transparent blue film and Chinese black and white film

These two kinds of film are relatively not considered to be good qualified, which means they are not very sticky, and not thick enough. The thickness ranges from 2c to 10c. Most customers apply these film in many ordinary processing. When the downstream need bending, or deep drawing, the film may suffer from cracking.

OTHER SURFACE FINISHES OF 304/L POLISHED STAINLESS STEEL SHEET/PLATE

*Not all finishes are available in all alloys - (contact Yieh United Sales for more information)

#1 Finish	Hot rolled, annealed and pickled.
#2D Finish	A uniform, dull silver gray mill finish that is applied to thinner stainless steel coils,the thickness of which has been reduced by cold rolling.
#2B Finish	A semi polished surface achieved by finishing with the equivalent of a 80 to 120 grit abrasive. This finish has a pronounced grit line.
#3 Finish	A semi polished surface achieved by finishing with the equivalent of a 80 to 120 grit abrasive. This finish has a pronounced grit line.
#4 Finish	Also called brushed, directional or satin finish. A is characterized by fine polishing grit lines that are uniform and directional in appearance. The final abrasive used in the process is 150 to 220 grit.
#4 Satin Brush Finish	150 to 180 grit finish A fine directional polish, typically used in the washroom accessories industry. Most 3.5″ floppy diskette cover plates have this finish.
#6 Finish	Polished finish achieved with the equivalent of a 240 grit abrasive. Finer grit lines and higher reflectivity than a No. 4 finish.
#7 Finish	Highly reflective surface obtained with the equivalent of a 320 grit abrasive. Minimal grit lines.
No. 8 or True #8 mirror	This is the most reflective mirror finish on the market. All of the polishing, or “grit,” lines from the preliminary polishing operations are removed. The look is that of a glass mirror. Sometimes referred to as a non directional mirror finish, Super 8, No. 9, Perfect No. 10, and even No. 12 mirror.
CMP Super #8 mirror	Chemical Mechanical Polished Super #8 mirror finished sheets are guaranteed to be free from any manufacturing defects. This product represents the ultimate in mirror polished stainless steel. It is available as a single-sided or double-sided mirror polished sheet.
Hairline finish	80 – 140 grit finish A well defined directional polish. Starting base substrate is a No. 4 finish sheet; these sheets are polished to provide a “continuous long grain” hairline look. A finish which is popular with architects for its aesthetic, it is equally popular with fabricators due to it’s ease of fabrication and finish matching properties after welding operations.
