FDA-Approved Stainless Steel Plate | Safe for Food Processing & Culinary Use

Technical Specifications

Performance & Features

1. Tensile Strength

Our steel plate stainless products meet stringent FDA standards for food safety while delivering exceptional mechanical performance.

• Grade 316L: Offers 520–670 MPa tensile strength, ideal for acidic food processing environments like dairy or seafood.
• Grade 304: Provides 515–700 MPa, widely used in kitchen equipment and food storage tanks.
• Grade 430: Maintains 450–600 MPa, suitable for non-acidic applications like baking trays.
  All grades comply with ASTM A240 and ISO 3506, with Mill Test Reports (MTRs) verifying traceability.

2. Bending Strength

Designed to withstand rigorous shaping without compromising hygiene:

• Cold-rolled sheets (≤6 mm) achieve 180° bends without cracking, ensuring seamless integration into conveyor systems.
• Thicker plates (e.g., 1/4 stainless steel plate) require controlled radii to prevent stress concentration, ideal for structural components in industrial kitchens.

3. Identification & Marking

Each plate includes laser-etched identifiers for compliance:

• Grade designation (e.g., SUS316L, 304).
• Batch number, FDA certification mark, and heat treatment code for full traceability.

4. Weight Calculation

Calculate plate weight using:
$\text{Weight (kg)}=\text{Thickness (mm)}\times \text{Width (m)}\times \text{Length (m)}\times 7.93(\text{Density})$
Example: A 1/4 stainless steel plate (6.35 mm × 1.5 m × 3 m) weighs 226 kg.

5. Why Stainless Steel Can Rust?

Even FDA-approved steel plate stainless may corrode under specific conditions:

• Chloride Exposure: Saltwater or acidic foods (e.g., pickling brine) induce pitting in 430-grade steel.
• Mechanical Damage: Scratches from abrasive tools weaken the passive chromium oxide layer, accelerating oxidation.
• Intergranular Corrosion: Poor welding or heat treatment in 304/316L grades reduces chromium carbide resistance, causing weld decay.
  Preventative measures include regular cleaning with pH-neutral detergents and avoiding zinc plated steel vs stainless steel hybrid setups, which risk galvanic corrosion.

Applications

• Food Processing: Conveyor belts, mixing tanks, canning equipment (FDA-compliant steel plate stainless).
• Culinary Use: Commercial-grade cookware, 1/4 stainless steel plate countertops, baking molds.
• Industrial Hygiene: Sanitary fittings, medical device components, pharmaceutical storage.

Zinc Plated Steel vs Stainless Steel: Key Differences

Why Choose Our Stainless Steel Plates?

1. FDA Compliance: Certified for direct food contact (grades 304/316L meet 21 CFR 175.300).
2. Superior Hygiene: Electrolytic polishing creates a non-porous surface, preventing bacterial growth.
3. Custom Fabrication: Precision laser cutting for complex shapes (tolerances ±0.1 mm).
4. Global Certifications: ISO 9001, RoHS, and ASTM A240 compliance.
5. Sustainability: 100% recyclable with eco-friendly production processes.
