Mechanical & Chemical Properties
Tensile Strength
The ultimate 430 Stainless Steel Coil boasts a tensile strength (σb) of ≥450 MPa, ensuring excellent resistance to deformation under heavy loads. This makes it suitable for structural applications like coiled stainless steel roofing and industrial machinery components.
Yield Strength
With a minimum yield strength (σ0.2) of ≥205 MPa, the coil maintains structural integrity even under prolonged stress, making it ideal for stainless steel siding nails coil and automotive trim.
Elongation & Formability
The elongation rate (δ5) of ≥22% allows for superior formability, enabling complex shaping without cracking. This property is critical for applications requiring precision bends, such as HVAC systems and kitchen equipment.
Weight Calculation
To calculate the weight of a coiled stainless steel sheet:
Weight (kg) = Thickness (mm) × Width (mm) × Length (m) × Density (7.7 g/cm³) ÷ 1000
Example: For a 1.5mm × 1219mm × 50m coil:
1.5 × 1219 × 50 × 7.7 ÷ 1000 = 703.3 kg
Why Does Stainless Steel Rust?
While 430 stainless steel is highly corrosion-resistant, rust can occur under extreme conditions:
- Chloride Exposure: Prolonged contact with saltwater or de-icing chemicals can degrade the passive chromium oxide layer.
- Mechanical Damage: Scratches or abrasions expose the underlying metal to oxidation.
- High Humidity: Combined with acidic pollutants, moisture accelerates pitting corrosion.
Regular cleaning and avoiding harsh environments can mitigate these risks.
