Mechanical Properties
-
Tensile Strength:
- 304/304L: Minimum ultimate tensile strength of 515 MPa, suitable for high-stress applications like structural frameworks and pressure vessels.
- 316/316L: Enhanced to 550 MPa due to molybdenum (2–3%), ideal for chloride-rich environments (e.g., coastal construction or chemical plants).
-
Bending Strength:
- Withstands 180° cold bending (mandrel diameter = 3x sheet thickness) without cracking. Certified for use in heat exchangers and HVAC ducting.
Identification & Marking
- Laser Etching: Each sheet is marked with grade (e.g., 304), thickness, heat number, and ASTM/EN certification.
- Color Coding: Blue for 304, yellow for 316, and green for duplex grades to simplify inventory management.
Weight Calculation Formula
Weight per square meter (kg/m²) = Thickness (mm) × 7.93 (density).
Example: A 3mm-thick cold rolled stainless steel sheet/plate weighs .
Why Does Stainless Steel Rust?
While stainless steel resists corrosion due to its chromium oxide layer (≥10.5% Cr), rust can occur under extreme conditions:
- Chloride Exposure: Saltwater or bleach degrades the passive layer, causing pitting (common in 304 without Mo).
- Galvanic Corrosion: Contact with carbon steel or copper in humid environments accelerates oxidation.
- High-Temperature Oxidation: Prolonged exposure above 870°C (1600°F) depletes chromium, leading to scaling.
Manufacturing Process
| Step | Description |
|---|---|
| Cold Rolling | Hot-rolled coils are processed at room temperature to achieve precise thickness and surface finish. |
| Solution Annealing | Heated to 1040–1120°C and water-quenched to restore ductility and corrosion resistance. |
| Surface Treatment | Pickling with HNO3/HF to remove scale, followed by passivation for enhanced oxide layer. |
| Quality Inspection | Eddy current testing, hydrostatic checks, and spectrometric analysis for compliance. |
