321 Stainless Steel Characteristics
Alloy 321 (UNS S32100) is a titanium-stabilized austenitic stainless steel that provides excellent resistance to intergranular corrosion following exposure to temperatures between 800-1500°F (427-816°C). The addition of titanium stabilizes the alloy against chromium carbide formation.
Key Advantages:
  • Superior resistance to intergranular corrosion in sensitization temperature range
  • Enhanced creep and stress rupture properties compared to 304 and 304L alloys
  • Excellent oxidation resistance up to 1500°F (816°C)
  • Good low-temperature toughness
  • Easy welding and standard shop fabrication compatibility
321H Variant
Alloy 321H (UNS S32109) features higher carbon content (0.04-0.10) for enhanced creep resistance and superior strength at temperatures above 1000°F (537°C). This composition often enables dual certification.
