321 Stainless Steel Plate – Advanced Engineering Profile
- Designation: UNS S32100 / Werkstoff Nr. 1.4541
- Structure: Titanium-Stabilized Austenitic Steel
- Compliance: ASTM A240, EN 10088-3, ISO 9445
Properties & Benefits of 321 Stainless Steel Plate
-
Thermal Fatigue Resistance
Engineered to withstand repeated thermal cycling (e.g., rapid heating/cooling) without cracking, thanks to titanium’s carbide stabilization. Ideal for jet engine components and afterburner systems. -
Stress Corrosion Cracking (SCC) Mitigation
Superior resistance to chloride-induced SCC compared to 304/304L, validated per ASTM G36 testing in boiling MgCl₂ environments. -
Cryogenic Compatibility
Maintains ductility and toughness down to -320°F (-196°C), suitable for LNG storage and cryogenic piping.
Material Science Insights of 321 Stainless Steel Plate
-
Metallurgical Design
Titanium (Ti ≥ 5×C) binds carbon to form TiC, preventing chromium depletion at grain boundaries. Post-production stabilization annealing ensures homogeneous microstructure. -
Phase Stability
Retains austenitic structure even after prolonged high-temperature exposure, avoiding harmful sigma phase formation below 1600°F (870°C).
Performance Benchmarking
| Property | 321 Stainless | 304 Stainless | 316L Stainless |
|---|---|---|---|
| Max Service Temp | 1500°F (815°C) | 1400°F (760°C) | 1400°F (760°C) |
| Creep Strength | 18 MPa @ 1000°F | 12 MPa @ 1000°F | 14 MPa @ 1000°F |
| HCl Resistance | Good (≤10% conc.) | Poor | Moderate |
