About 321 Stainless Steel
Titanium-bearing stainless steels are stabilized against carbide precipitation and designed for operation within the damaging temperature range where carbide precipitation develops. In this type of steel, the carbon combines preferentially with titanium to form harmless titanium carbide, leaving the chromium in solution to maintain full corrosion resistance. Type 321 is basic type 304 modified by adding titanium in an amount at least 5 times the carbon plus nitrogen contents.

Key Features of 321 Stainless Steel
  • Immune to intergranular corrosion when heated within the carbide precipitation range
  • Titanium addition eliminates chromium carbide formation at grain boundaries
  • Superior high temperature properties compared to 304 or 304L grades
  • Suitable for intermittent heating up to 1500°F, continuous service to 1650°F
  • May be susceptible to chloride stress cracking
  • Excellent weldability in field applications
  • Type 321H has higher carbon content for improved high temperature creep properties
Common Applications
  • Aircraft exhaust manifolds
  • Expansion joints and bellows
  • Furnace parts and heating element tubing
  • Heat exchangers
  • Woven or welded screens for high temperature mineral processing
  • Spiral welded tube for burner pipes and flues
Technical Background
Grades 321 and 347 are basic austenitic 18/8 steels (Grade 304) stabilized by Titanium (321) or Niobium (347) additions. These grades resist intergranular corrosion after heating within the carbide precipitation range of 425-850°C. Grade 321 is ideal for applications up to 900°C, combining high strength, scaling resistance, phase stability, and subsequent aqueous corrosion resistance.
Grade 321H is a modification with higher carbon content for improved high temperature strength. While 321 has excellent forming and welding characteristics with outstanding toughness even at cryogenic temperatures, it does not polish well and is not recommended for decorative applications.

Alternative GradeSelection Criteria
304LWhen requirement is for intergranular corrosion resistance without high temperature strength needs
3CR12For mild high temperature environments up to approximately 600°C
304HFor mild high temperature environments up to approximately 800°C
310For operating environments up to approximately 1100°C
S30815 (253MA)For operating environments up to approximately 1150°C
