Mechanical Properties
Tensile Strength
The 06Cr18Ni11Ti stainless steel plate exhibits a minimum tensile strength of 520 MPa and a yield strength of ≥205 MPa. Its austenitic structure, enhanced by titanium (Ti), ensures exceptional resistance to stress corrosion cracking, making it ideal for stainless steel plate heat exchanger systems exposed to high-temperature fluids or aggressive media like chlorides.
Bending Strength
With ≥40% elongation in annealed conditions, this material supports seamless cold-forming processes such as deep drawing and roll bending. Its ductility minimizes cracking risks during fabrication of custom stainless steel plates for architectural or industrial applications.
Identification & Marking
- Standard Markings:
- GB/T: 06Cr18Ni11Ti
- AISI: 321 (equivalent)
- EN: 1.4541
- Surface Marking: Laser-etched with grade, thickness, and batch number for full traceability.
Weight Calculation
Weight (kg) = Thickness (mm) × Width (m) × Length (m) × Density (7.93 g/cm³)
Example: A 10mm × 1.5m × 3m plate weighs 357.3 kg (10×1.5×3×7.93).
Why Stainless Steel Corrodes?
Despite its superior corrosion resistance, 06Cr18Ni11Ti may rust under extreme conditions:
- Chloride Exposure: Chlorides (e.g., seawater, industrial salts) penetrate the chromium oxide layer, causing localized pitting.
- Intergranular Corrosion: Prolonged exposure to 450–850°C triggers chromium carbide formation at grain boundaries, reducing corrosion resistance.
- Galvanic Corrosion: Contact with dissimilar metals (e.g., carbon steel) in humid environments accelerates electrochemical degradation.
- Mechanical Damage: Improper handling or abrasive tools can scratch the surface, exposing the base metal to oxidation.
Key Features & Applications
Material Advantages
- Corrosion Resistance: Titanium (Ti) stabilizes the alloy against sensitization, ideal for stainless steel divider plate systems in food processing or chemical plants.
- High-Temperature Stability: Retains structural integrity up to 900°C, suitable for boilers, exhaust systems, and heat treatment equipment.
- Hygienic Design: Non-porous 2B finish complies with FDA and EU hygiene standards for medical devices and pharmaceutical machinery.
Processing Techniques
| Process | Description |
|---|---|
| Cold Rolling | Enhances dimensional precision (±0.05mm) and surface uniformity. |
| Solution Treatment | Restores corrosion resistance by dissolving carbides at 1050–1100°C. |
| PVD Coating | Adds stainless steel divider plate aesthetics (e.g., black ion-plated finishes) for architectural panels. |
