Mechanical & Functional Properties
Tensile Strength
stainless steel sheet plate for sale exhibits tensile strengths ranging from 450–1035 MPa, depending on the grade and processing method. For example:
- Grade 304: 515–620 MPa (Annealed) / 860 MPa (Cold Worked), ideal for food processing and architectural applications.
- Grade 409: 450–550 MPa, optimized for automotive exhaust systems due to moderate heat resistance.
- Martensitic 410: 760–827 MPa (Tempered), suitable for high-stress components like valves and turbine blades.
Bending Strength
Bending performance correlates with ductility and yield strength. For instance:
- Austenitic 316L: Yield strength of 290 MPa ensures excellent formability for stainless steel diamond plate sheets used in industrial flooring and stair treads.
- Ferritic 430: Higher chromium content (16–18%) enhances corrosion resistance but requires controlled bending radii to avoid cracking.
Identification & Marking
Stainless steel plates are marked per international standards:
- ASTM/ASME: Laser-engraved grade (e.g., "304"), heat number, and manufacturer’s logo.
- ISO/DIN: Material numbers (e.g., 1.4512 for 409) and dimensional tolerances.
- Certifications: Mill Test Reports (MTRs) validate chemical composition and mechanical properties.
Weight Calculation
Weight (kg/m²) = Thickness (mm) × Width (mm) × Length (m) × Density (g/cm³) / 1,000
Example: A stainless steel 409 sheet plate measuring 1.2 mm × 1000 mm × 1 m weighs:
1.2 × 1000 × 1 × 7.75 / 1,000 = 9.3 kg/m².
For bulk orders, total coil weight = kg/m² × coil length (m).
Why Does Stainless Steel Rust?
While stainless steel diamond plate sheets are corrosion-resistant, rust can occur under specific conditions:
- Low Chromium Content: Grades like 409 (<10.5% Cr) lack sufficient chromium oxide layer formation.
- Chloride Exposure: Coastal or industrial environments accelerate pitting corrosion in non-stabilized grades (e.g., 304 vs. 316L).
- Galvanic Corrosion: Contact with carbon steel in electrolytes creates electrochemical degradation.
- Mechanical Damage: Abrasive tools or scratches expose raw steel to oxidation.
- High-Temperature Oxidation: Prolonged exposure above 400°C degrades protective layers in grades without titanium stabilization (e.g., 321).
