Technical Details
Tensile & Bend Strength
The stainless steel plate exhibits exceptional tensile strength (515-690 MPa), ensuring structural integrity under heavy loads. Its high ductility (40% elongation) allows for complex forming without cracking. The bend strength is optimized for industrial applications, with a minimum bend radius of 2x thickness (8mm for 4mm plate), making it ideal for fabricating stainless steel railroad tie plates or curved components in harsh environments.
Identification & Certification
Each plate is laser-marked with grade (316/316L), thickness, and batch number. Certifications include ISO 9001, SGS, and Mill Test Reports (MTRs) verifying chemical composition (16-18% Cr, 10-14% Ni, 2-3% Mo). Compliant with ASTM A240 for corrosion resistance and ASME for pressure vessel use.
Weight Calculation
Weight per sheet = Thickness (mm) × Width (m) × Length (m) × Density (7.93 g/cm³).
Example: 4mm × 1.22m × 2.44m = 94.8 kg/sheet. Custom sizes available for bulk orders.
Why Stainless Steel Rusts?
While stainless steel plate resists rust due to its chromium oxide layer, corrosion may occur in extreme conditions:
- Chloride Exposure: Prolonged contact with seawater or de-icing salts can cause pitting.
- Mechanical Damage: Scratches or abrasions disrupt the passive layer, requiring prompt cleaning.
- High-Temperature Oxidation: Above 800°C, chromium oxide degrades; 316L is preferred for welding.
- Galvanic Corrosion: Avoid contact with carbon steel in humid environments.
Why Choose Our Stainless Steel Plates?
- Superior Corrosion Resistance: Enhanced molybdenum content (2-3%) for marine and chemical environments.
- Precision Manufacturing: Cold-rolled surfaces (2B/BA) ensure uniformity, critical for stainless steel license plate screws and architectural uses.
- Fast Delivery: 15-day lead time for bulk orders, with in-stock sizes (1220x2440mm, 1500x3000mm).
- Custom Solutions: Tailored thickness (0.3-100mm), widths (up to 3000mm), and finishes (No.4, mirror).
- Eco-Friendly: 100% recyclable, compliant with RoHS and ISO 14001.
- Technical Support: Free metallurgical guidance for welding, cutting, and fabrication.
