Technical Properties
Tensile & Bend Strength
Our ASTM-compliant stainless steel plates deliver exceptional tensile strength (520–860 MPa), ideal for structural applications in corrosive environments. For instance, nickel plated vs stainless steel variants balance corrosion resistance and conductivity, making them suitable for electrical enclosures or marine hardware. Bend strength is enhanced through cold rolling, achieving up to 1.5x higher rigidity than annealed plates, perfect for load-bearing components like stainless steel suction plate systems in industrial vacuums.
Weight Calculation
Calculate weight per unit area using:
Example: A stainless steel divided plate (3mm thick) weighs ~23.8 kg/m². For perforated plates, reduce weight by 15–30% based on open area ratio.
Identification Methods
- ASTM/EN Standards: Laser-etched codes (e.g., "304" or "316L") for traceability.
- Surface Marking: QR codes linked to mill test reports (MTRs) for chemical composition and heat treatment data.
Why Stainless Steel Rusts & Prevention
While stainless steel resists rust through its chromium oxide layer (≥10.5% Cr), specific conditions compromise protection:
- Chloride Exposure: Coastal environments or chemical spills trigger pitting corrosion, especially in nickel plated vs stainless steel with incomplete passivation.
- Mechanical Damage: Scratches on HL finish surfaces expose the base metal to oxidation. Use non-abrasive cleaners for maintenance.
- Galvanic Corrosion: Contact with dissimilar metals (e.g., aluminum) accelerates degradation. Isolation pads or dielectric coatings are recommended.
- Organic Contaminants: Food acids or pollutants degrade the passive layer. Clean biweekly with pH-neutral solutions.
Applications
- Industrial: Stainless steel suction plate for vacuum systems; stainless steel divided plate for food processing separation.
- Architectural: HL finish panels for façades; 2B finish for hygienic surfaces in hospitals.
- Automotive: Nickel plated vs stainless steel components for corrosion-resistant brackets.
