Key Mechanical & Physical Properties
Tensile Strength
The stainless steel plate 904L exhibits exceptional tensile strength ranging from 490 MPa to 930 MPa, making it ideal for high-stress applications in corrosive environments. This property ensures structural integrity even under extreme mechanical loads, such as in chemical processing reactors or marine equipment.
Yield Strength
With a minimum yield strength of 216 MPa, this stainless steel metal plate resists permanent deformation under pressure, ensuring longevity in industrial frameworks and architectural supports.
Elongation
A 35% elongation rate (A5%) provides superior ductility, enabling complex forming processes like deep drawing or bending without cracking.
Corrosion Resistance & Applications
904L stainless steel plate excels in environments with sulfuric acid, phosphoric acid, and chloride exposure due to its high chromium (19-23%), nickel (23-28%), and molybdenum (4-5%) content. Key applications include:
- Chemical & Petrochemical Equipment: Reactors, heat exchangers, and pipelines.
- Marine Engineering: Seawater desalination systems and offshore platforms.
- Automotive: Stainless steel license plate frames and exhaust components.
Weight Calculation
Formula:
Weight (kg) = Thickness (mm) × Width (m) × Length (m) × Density (8.0 g/cm³)
Example: A 3mm × 1.5m × 6m plate weighs 3 × 1.5 × 6 × 8.0 = 216 kg.
Why Stainless Steel Rusts?
While 904L is highly corrosion-resistant, improper handling or extreme conditions (e.g., prolonged exposure to hydrochloric acid >2% concentration) can cause localized rust. Key factors include:
- Chloride Exposure: Coastal or de-icing salt environments accelerate pitting.
- Contamination: Iron particles from tools or storage areas induce galvanic corrosion.
- Temperature: Prolonged exposure above 60°C in chloride-rich settings may reduce passivation.
