Alloy 303 (UNS S30300) is an austenitic stainless steel developed for applications requiring extensive machining operations. The alloy has a sulfur addition which assists in breaking up turning while reducing drag on the cutting tool when compared to the machining characteristics of the conventional 18-8 stainless steels.

ADDITIONAL PROPERTIES OF 303 STAINLESS STEEL SHEET/PLATE

• Heat Treatment
  Annealing - Heat to a minimum temperature of 1900ºF (1038ºC) and water quench or rapid cool by other means.
  Hardening - Alloy 303 cannot be hardened by thermal treatment, it can only be hardened by cold working.
• Cold Forming
  The cold formability of alloy 303 is adversely impacted by the high sulfur content. The alloy may be bent with a generous bend radius, however, when cold forming is required, 304 should be utilized.
• Hot Forming
  The high sulfur content of alloy 303 also has a detrimental impact on hot workability. If hot forming is required, once again, 304 should be considered as an alternate selection.
• Machining
  Alloy 303 was developed specifically for ease of machining. The sulfur addition assists in breaking up turnings which reduces drag on the cutting tool. It produces small brittle chips and may be machined at high speeds with deep cuts and heavy feed.

• Welding
  Alloy 303 is not recommended for applications requiring welding. If it is necessary to weld the alloy, AWS E312 fillter metal may be considered.

SURFACE FINISH OF 303 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.
