Performance Attributes

1. Tensile & Bend Strength

The S31600 grade combines high tensile strength (520–720 MPa) with exceptional bend resistance (1.5× tensile strength) due to its austenitic microstructure stabilized by 16–18% chromium, 10–14% nickel, and 2–3% molybdenum. This makes it ideal for heavy-duty applications like structural beams, stainless steel griddle plates, or marine hardware. The material retains its integrity under dynamic loads up to 500°C, preventing deformation or cracking.

 

2. Identification & Certification

  • ASTM Standards: Laser-etched UNS S31600 identifiers ensure traceability.
  • EN 1.4401 Compliance: Meets EU standards for chemical composition and mechanical properties.
  • Surface Marking: Includes mill codes, heat numbers, and stainless steel gold plated chain compatibility notes for industrial tracking.

3. Weight Calculation

Use the formula:

For example, a stainless steel gold plate with a 3 mm thickness and 2 m² area weighs 47.58 kg.

4. Causes of Stainless Steel Rust

Despite its corrosion resistance, localized rust may occur due to:

  • Chloride Exposure: Coastal salt or industrial chemicals degrade the passive chromium oxide layer.
  • Mechanical Damage: Scratches or improper welding expose the base metal to oxidation.
  • Thermal Stress: Rapid temperature changes (e.g., in stainless steel griddle plates) can induce micro-cracks, accelerating corrosion.

Material Advantages

Enhanced Durability

  • Molybdenum Boost: 2–3% molybdenum enhances resistance to pitting and crevice corrosion, making it suitable for marine or chemical environments.
  • High-Temperature Stability: Retains 85% of its strength at 500°C, ideal for industrial ovens or exhaust systems.

Precision Manufacturing

  • HL Polishing: Achieves ≤Ra 0.1 μm surface roughness for stainless steel gold plate aesthetics or hygienic food-grade surfaces.
  • Laser Cutting: Tolerance ±0.1 mm ensures seamless integration into architectural grids or machinery.

Sustainability

  • 100% Recyclable: Reduces environmental impact and lifecycle costs.
