Technical Properties
Tensile & Bend Strength
Our S31600 stainless steel plate delivers exceptional tensile strength (≥520 MPa), making it ideal for structural applications in corrosive environments like marine or chemical processing. The addition of 2-3% molybdenum enhances chloride resistance, outperforming 304-grade steel in saltwater and acidic conditions. For bend strength, cold-rolled variants achieve up to 1.5x higher rigidity than annealed plates, perfect for load-bearing components like offshore platforms or heat exchangers.
Weight Calculation
Calculate weight per unit area using:
Example: A 5mm-thick stainless steel perforated plate with 20% open area weighs ~31.9 kg/m².
Identification Methods
- ASTM/EN Standards: Laser-etched codes (e.g., "S31600" for molybdenum-enriched grades).
- Surface Marking: QR codes linked to mill test reports for traceability.
Why Stainless Steel Rusts & Prevention
While stainless steel resists rust through its chromium oxide layer (≥16% Cr), specific conditions compromise protection:
- Chloride Exposure: Coastal or industrial environments accelerate pitting corrosion in S31600 if passivation is incomplete.
- Mechanical Damage: Scratches on HL finish surfaces expose the base metal to oxidation. Use non-abrasive cleaning tools.
- Galvanic Corrosion: Contact with dissimilar metals (e.g., carbon steel) triggers electrochemical degradation. Isolation pads are recommended.
- Organic Contaminants: Food acids or pollutants degrade the passive layer. Clean biweekly with pH-neutral solutions.
Applications
- Industrial: Heat exchangers, pressure vessels (S31600 for chloride-rich media).
- Architectural: Stainless steel perforated plate for façades, sunscreens, and soundproofing.
- Medical: Surgical tools and implants due to biocompatibility.
- Marine: Shipbuilding components with HL finish for anti-slip surfaces.
