5.Standards: ASTM/ASME UNS S30200
Type 302 Stainless Steel is widely used where higher strengths and higher work-hardening rates are desired, such as springs, at a relatively lower cost compared to 304/304L. This grade has good corrosion/oxidation resistance and weldability.

APPLICATION OF 302 STAINLESS STEEL SHEET/PLATE
- Wire forming
- Formed into all types of washers, springs, screens, and cables
- Food and beverage industry
- Pressure containing applications
- Sanitary or cryogenic applications
- Dish racks
- Washing machines
ADDITIONAL PROPERTIES OF 302 STAINLESS STEEL SHEET/PLATE
Parts can be annealed at 1900°F–2050°F held for minimum 60 minutes per inch of thickness and water quenched. Prolonged exposure between 800°F–1500°F must be avoided to prevent embrittlement and loss of corrosion properties. This grade does not harden with heat treatment.
Like most other austenitic steels, this grade machines with rough and stringy chips. Therefore chip curlers can be beneficial.
This grade is readily weldable by any conventional methods employed for austenitic stainless steels. Type 308L/308LSi stainless steel filler is generally recommended. For specific application, contacting a welding expert is advised. For maximum corrosion resistance, annealing after welding is recommended. In hard condition, resistance welding is recommended to prevent softening.
- COLD WORKABILITY
This grade can be readily cold worked. This is a high strain-hardening grade. Operations such as wire drawing, forging, upsetting and bending are common. Severe forming may require intermediate annealing.
- HOT WORKABILITY
This grade can readily be hot worked. Heat initially to 2100°F–2300°F and can be finished as low as 1500°F. Severe reductions below 1700°F should be avoided. Parts should be water quenched after hot working for good corrosion resistance. For maximum corrosion resistance, parts should be annealed and water quenched.
- CORROSION RESISTANCE
This grade has good corrosion resistance in a wide variety of corrosive media, such as foodstuffs, sterilizing solutions, most organic chemicals and dyes, most petroleum products, steam and combustion gases. It resists nitric acid well, sulfuric acid moderately and halogen acids and halogen compounds poorly. For maximum corrosion resistance, material should be used in annealed condition and parts should be passivated.
SURFACE FINISH OF 302 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.
