Mechanical Properties
Tensile Strength
Our AISI 304/316 stainless steel plates deliver a minimum tensile strength of 520–620 MPa and yield strength of ≥210–290 MPa, ensuring exceptional load-bearing capacity for structural and industrial applications. This makes them ideal for high-stress environments like chemical processing tanks, marine hardware, and architectural frameworks.
Bending Strength
With ≥35% elongation in annealed conditions, these plates exhibit superior ductility for cold-forming processes like deep drawing and roll bending. The austenitic microstructure resists deformation, even under repetitive stress, making them compatible with the best drill bit for stainless steel plate for precision drilling.
Identification & Marking
- Standard Markings:
- AISI: 304 (UNS S30400), 316 (UNS S31600)
- EN: 1.4301 (304), 1.4401 (316)
- Surface Marking: Laser-etched with grade, thickness, and heat number for full traceability.
Weight Calculation
Weight (kg) = Thickness (mm) × Width (m) × Length (m) × Density (7.93 g/cm³)
Example: A 5mm × 1.2m × 2.4m plate weighs 114.5 kg (5×1.2×2.4×7.93).
Why Stainless Steel Corrodes?
While stainless steel is highly corrosion-resistant, AISI 304/316 plates may rust under extreme conditions:
- Chloride Exposure: Chlorides (e.g., seawater, de-icing salts) penetrate the chromium oxide layer, causing pitting corrosion.
- Intergranular Corrosion: Prolonged exposure to 500–800°C reduces chromium content at grain boundaries, accelerating oxidation.
- Mechanical Damage: Scratches or abrasions from improper tools (e.g., non-coated drill bits) expose the base metal to rust.
- Galvanic Corrosion: Contact with dissimilar metals (e.g., zinc plated screws vs stainless steel) in moist environments triggers electrochemical degradation.
Key Features & Applications
Material Advantages
- Corrosion Resistance: 18–20% chromium and 8–12% nickel form a self-repairing oxide layer.
- Hygienic: Non-porous 2B finish meets FDA standards for food processing and medical equipment.
- Aesthetic Versatility: Compatible with black ion plated stainless steel durability for decorative panels or luxury appliances.
Processing Techniques
| Process | Description |
|---|---|
| Cold Rolling | Enhances dimensional accuracy (±0.05mm) and surface uniformity. |
| Pickling | Removes oxide layers using HNO3/HF solutions for optimal corrosion resistance. |
| Polishing | Achieves mirror (No.8) or hairline (HL) finishes for architectural cladding. |
Comparative Insights
