Detailed Technical Descriptions
1. Tensile & Bend Strength
Stainless steel flat bar exhibits exceptional tensile strength (up to 720 MPa for Grade 304), making it suitable for load-bearing applications like flat top grill stainless steel frames. Its bend strength is enhanced through controlled annealing, ensuring structural integrity under cyclic thermal stress (e.g., repeated heating/cooling in stoves).
2. Weight Calculation
Use the formula to estimate flat bar weight:
Weight (kg/m) = Thickness (mm) × Width (mm) × 0.00785
Example: A 10mm × 50mm stainless steel flat bar weighs ≈3.925 kg/m.
3. Identification Marking
All products are laser-etched with:
- Grade (e.g., 304, 316L)
- Batch Number (for traceability)
- ASTM/EN Standard (e.g., ASTM A276, EN 10088-3)
This ensures compliance with global quality benchmarks.
4. Causes of Stainless Steel Corrosion
Despite high durability, corrosion may occur due to:
- Chloride Exposure: Coastal environments or de-icing salts degrade protective chromium oxide layers.
- Galvanic Corrosion: Contact with dissimilar metals (e.g., carbon steel) in humid conditions.
- Thermal Stress: Excessive temperatures (>400°C for 304 grade) may weaken oxidation resistance.
Applications & Custom Solutions
- Flat top grill stainless steel: Grade 430 bars are cost-effective for heat-resistant grill surfaces.
- Stainless steel flat top stove: Polished 316L bars resist acidic food residues and high-temperature warping.
- Architectural cladding: Brushed or mirror-finished bars for modern façades and handrails.
