Mechanical Properties
Tensile Strength
The 316L stainless steel plate offers a minimum tensile strength of 520 MPa and a yield strength of ≥205 MPa. Its low-carbon composition (≤0.03% C) prevents carbide precipitation during welding, ensuring structural integrity in high-temperature environments like industrial furnaces or exhaust systems. This makes it ideal for stainless steel grill plate applications, where thermal cycling and mechanical stress are common.
Bending Strength
With ≥40% elongation in annealed conditions, 316L supports seamless cold-forming processes such as deep drawing and roll bending. Its austenitic microstructure resists deformation even at elevated temperatures, enabling precise fabrication of camping stainless steel plates or complex geometries for chemical reactors.
Identification & Marking
- Standard Markings:
- AISI/UNS: S31603
- EN: 1.4404
- GB/T: 022Cr17Ni12Mo2
- Surface Marking: Laser-etched or stamped with grade, thickness, heat number, and RoHS compliance for full traceability.
Weight Calculation
Weight (kg) = Thickness (mm) × Width (m) × Length (m) × Density (7.93 g/cm³)
Example: A 3mm × 1.2m × 2.4m plate weighs 68.7 kg (3×1.2×2.4×7.93).
Why Stainless Steel Corrodes?
Despite its exceptional corrosion resistance, 316L may rust under extreme conditions:
- Chloride Exposure: Chlorides (e.g., seawater, road salts) penetrate the chromium oxide layer, causing pitting corrosion.
- 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: Abrasive tools or improper handling can scratch the surface, exposing the base metal to oxidation.
Key Features & Applications
Material Advantages
- Heat Resistance: Retains strength up to 900°C, ideal for stainless steel plate covers in boilers or heat exchangers.
- Corrosion Resistance: Molybdenum (2–3%) enhances resistance to chlorides and acids, suitable for marine or chemical processing.
- Hygienic Design: Non-porous 2B finish meets FDA standards for food-grade camping stainless steel plates.
Processing Techniques
| Process | Description |
