Austenitic Stainless Steel 301, 302, 316, 321
Grade 301L: It is applicable for higher work hardening rate grade.It could be required for certain roll formed or stretch formed components.
Grade 302HQ: Lower work hardening rate grade. It could be needed for cold forging of screws, bolts and rivets.
Grade 303: Higher machinability needed; lower corrosion resistance; acceptable formability and weldability.
- Grade 316: Used when higher resistance to pitting and crevice corrosion is required, also in chloride environments
Grade 321: Better resistance to temperatures of around 600-900°C. It has higher hot strength.
Grade 3CR12: It has lower cost; reduced corrosion resistance and resulting discoloration are acceptable.
Grade 430: It has lower cost; reduced corrosion resistance and fabrication characteristics are acceptable.
Austenitic Stainless Steel 301, 302, 316, 321 Characteristics:
- Forming and welding properties
- Corrosion/ oxidation resistance thanks to the chromium content
- Deep drawing quality
- Excellent toughness, even down to cryonegic temperatures which are defined as very low temperatures
- Low temperature properties responding well to hardening by cold working
- Ease of cleaning, ease of fabrication, beauty of appearance
