About 321 Stainless Steel
Type 321 stainless steel is a titanium-stabilized austenitic stainless steel designed for operation within the damaging temperature range where carbide precipitation develops. The titanium addition (minimum 5 times carbon plus nitrogen content) preferentially combines with carbon to form harmless titanium carbide, maintaining full chromium content for optimal corrosion resistance.
Chemical Composition
| Element | Min | Max |
|---|---|---|
| C | - | 0.08 |
| Mn | - | 2.00 |
| Si | - | 0.75 |
| P | - | 0.045 |
| S | - | 0.030 |
| Cr | 17.0 | 19.0 |
| Ni | 9.0 | 12.0 |
| N | - | 0.10 |
| Ti | 5(C+N) | 0.70 |
Key Features
- Immune to intergranular corrosion when heated within carbide precipitation range
- Titanium addition prevents chromium carbide formation at grain boundaries
- Superior high-temperature properties compared to 304/304L grades
- Suitable for intermittent service up to 1500°F (815°C)
- Continuous service capability up to 1650°F (900°C)
- Excellent weldability for field applications
- Type 321H variant offers improved high-temperature creep properties
Typical Applications
- Aircraft exhaust manifolds
- Expansion joints and bellows
- Furnace components and heating element tubing
- Heat exchangers
- High-temperature mineral processing screens
- Burner pipes and flue systems
Technical Background
Grade 321 is an 18/8 austenitic stainless steel (similar to Grade 304) stabilized with titanium additions. This stabilization prevents sensitization to intergranular corrosion after exposure to temperatures between 425-850°C. The alloy combines high strength, scaling resistance, phase stability, and subsequent aqueous corrosion resistance, making it ideal for applications up to approximately 900°C.
While Grade 304L is often preferred for general corrosion resistance applications, 321 offers superior high-temperature strength above 500°C. For welding applications, Grade 347 is recommended as the consumable since titanium doesn't transfer well across high-temperature arcs.
Alternative Grade Comparison
| Alternative Grade | Selection Criteria |
|---|---|
| 304L | When requirement is primarily intergranular corrosion resistance without high-temperature strength needs |
| 3CR12 | For mild high-temperature environments up to approximately 600°C |
| 304H | For moderate high-temperature applications up to approximately 800°C |
| 310 | For extreme high-temperature environments up to approximately 1100°C |
| S30815 (253MA) | For ultra-high temperature applications up to approximately 1150°C |
