Corrosion-Resistant Stainless Steel Plate | Saltwater & Chemical Exposure Solutions

Product Specifications

Key Features & Benefits

1. Unmatched Corrosion Resistance
   Engineered for harsh environments, our stainless steel round plate resists pitting, crevice corrosion, and stress corrosion cracking (SCC) in saltwater, chemical, and acidic conditions. Grades like 316L (2-3% Mo) and 2205 Duplex (PREN ≥35) outperform standard 304 stainless steel.

2. High Mechanical Strength

   • Tensile Strength: 580–930 MPa (316L to 2205 Duplex).
   • Yield Strength: 290–550 MPa (ideal for structural and marine applications).

3. Aesthetic & Functional Versatility
   Available in stainless steel gold plated finishes for decorative uses like stainless steel gold plated jewelry, or industrial-grade finishes for offshore rigs and chemical tanks.

4. Custom Fabrication
   Precision-cut stainless steel round plate for machinery, architectural cladding, or custom jewelry molds.

Technical Details

1. Tensile Strength

Tensile strength measures the maximum stress a material can endure before fracture. Our plates undergo rigorous ASTM E8 testing:

• 316L Stainless Steel: 580–860 MPa (ideal for marine and chemical exposure).
• 2205 Duplex: 620–930 MPa (dual-phase structure enhances load-bearing capacity).
• 904L Stainless Steel: 490–685 MPa (excellent for sulfuric acid environments).

2. Bend Strength

Bend strength ensures flexibility without cracking. Tested via ASTM E290 three-point bending:

• Cold-Rolled Plates: Achieve 180° bends for forming stainless steel gold plated jewelry components.
• Heat-Treated Plates: Retain ductility even after hardening, suitable for structural uses.

3. Identification & Marking

• Laser Etching: Permanent grade markings (e.g., "316L," "2205") for traceability.
• Heat Numbers: Unique batch codes linked to mill test certificates (MTCs).
• Surface Codes: "2B" for cold-rolled, "BA" for bright annealed finishes.

4. Weight Calculation

Formula:
Weight (kg) = Thickness (mm) × Width (m) × Length (m) × Density (7.93–8.0)
Example: A 6mm × 1.2m × 2.4m stainless steel round plate (Grade 316L) weighs 137.5 kg.

5. Why Does Stainless Steel Rust?

Despite its corrosion resistance, rust can occur due to:

• Chloride Exposure: Saltwater or de-icing agents degrade the chromium oxide layer, especially in grades with low PREN values.
• Mechanical Damage: Scratches or welding defects expose the base metal to oxidation.
• Galvanic Corrosion: Contact with carbon steel or dissimilar metals accelerates rusting.
• Low-Quality Alloys: Substandard chromium/molybdenum content in cheaper grades reduces resistance.
