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 Grade Comparison

Alternative Grade	Selection Criteria
304L	When requirement is for intergranular corrosion resistance without high temperature strength needs
3CR12	For mild high temperature environments up to approximately 600°C
304H	For mild high temperature environments up to approximately 800°C
310	For operating environments up to approximately 1100°C
S30815 (253MA)	For operating environments up to approximately 1150°C
