Mirror-Polished Stainless Steel Baking Sheet: Custom-Cut Solutions

Mirror-Polished Stainless Steel Baking Sheet: Custom-Cut Solutions

​Product Overview

Our ​stainless steel baking sheet combines premium ​stainless steel sheet metal with a ​mirror-polished finish (8K/BA), delivering unmatched durability and aesthetic appeal. Designed for commercial kitchens, food processing, and high-end culinary applications, this sheet resists corrosion, heat distortion, and staining while maintaining a hygienic surface. Available in ​custom-cut sizes and compliant with ​ASTM A240/A666 standards, it’s engineered for versatility and longevity.

​Technical Specifications

​Key Properties & Performance

​Tensile and Bending Strength

The ​stainless steel baking sheet exhibits exceptional ​tensile strength (515–860 MPa for 304 grade) due to its austenitic microstructure. This ensures resistance to deformation under heavy loads, such as industrial baking trays supporting 50–100 lbs. ​Bending strength is enhanced by cold-rolled processing, allowing the sheet to withstand repeated flexing without cracking—ideal for high-volume food production lines.

​Weight Calculation

Use the formula to estimate sheet weight:
$\text{Weight (lbs)}=\text{Length (in)}\times \text{Width (in)}\times \text{Thickness (in)}\times 0.29$
Example: A 24"x36" 16 GA (0.063") sheet weighs:
$24\times 36\times 0.063\times 0.29=15.8\text{lbs}$

​Rust Prevention & Causes

While ​stainless steel sheet metal is corrosion-resistant, rust may occur due to:

1. ​Chloride Exposure: Prolonged contact with salt or acidic foods degrades the chromium oxide layer.
2. ​Mechanical Scratches: Abrasive cleaning tools disrupt surface integrity, accelerating oxidation.
3. ​Low Oxygen Environments: Stagnant moisture in crevices inhibits self-repair of the passive layer.
4. ​Carbon Contamination: Improper welding introduces carbon, causing intergranular corrosion.

​Manufacturing & Identification

​Production Process

1. ​Cold Rolling: Raw 304/316L coils are cold-rolled to achieve precise ​stainless steel sheet gauge chart specifications.
2. ​Annealing & Pickling: Heat-treated at 1010–1120°C to restore ductility, followed by acid bath cleaning.
3. ​Mirror Polishing: Electrolytic polishing with 800–1500-grit abrasives creates a Ra ≤0.02μm surface.
4. ​Laser Cutting: CNC-guided lasers ensure ±0.5mm accuracy for custom shapes.

​Identification Markings

Each sheet is laser-etched with:

• ​Grade (304/316L)
• ​Thickness (GA/mm) per ​stainless steel sheet gauge chart
• ​Heat Number for traceability
• ​Compliance Marks (ASTM/ISO)
