Key Features
Mechanical & Chemical Properties
- Superior Corrosion Resistance: The stainless steel exhaust pipe contains 16–18% chromium and 2–3% molybdenum, offering exceptional resistance to pitting and crevice corrosion in chloride-rich environments like marine or automotive exhaust systems.
- High-Temperature Stability: Retains tensile strength (>500 MPa) and structural integrity at temperatures up to 900°C, ideal for turbochargers and industrial furnaces.
- Seamless Construction: Cold-drawn or hot-extruded seamless pipes eliminate weld seams, reducing weak points and ensuring uniform stress distribution under vibration or pressure.
Weight Calculation Formula
Calculate pipe weight using:
Example: For a stainless steel pipe diameter of 100mm with 5mm wall thickness:
Bending Strength & Fatigue Resistance
- Bend Strength: Seamless 316 pipes withstand 180° bending without cracking, critical for custom stainless steel muffler pipe configurations.
- Cyclic Load Resistance: Fatigue strength of 240 MPa at 10⁷ cycles ensures longevity in high-vibration automotive or aerospace applications.
Manufacturing Process
Precision engineering for unmatched reliability.
| Stage | Description |
|---|---|
| Material Selection | 316/316L billets sourced from ISO 9001-certified mills with traceable PMI reports. |
| Forming | Cold drawing (for thin walls) or hot extrusion (for thick walls) to ensure seamless integrity. |
| Heat Treatment | Solution annealing at 1050°C followed by rapid quenching to optimize corrosion resistance. |
| Surface Treatment | Pickling, electropolishing, or passivation to achieve Ra ≤0.8μm for reduced friction and bacterial growth. |
| Quality Assurance | Hydrostatic testing (1.5x max pressure), eddy current inspection, and third-party lab certification. |
Why Stainless Steel Rusts & Prevention
While stainless steel exhaust pipes are inherently corrosion-resistant, improper handling or environmental factors can cause localized rusting:
- Chloride Exposure: Prolonged contact with road salt or seawater degrades the chromium oxide layer. Use stainless steel pipe clamps with insulating sleeves to prevent galvanic corrosion.
- Mechanical Damage: Scratches from improper tooling expose the base metal. Post-installation passivation restores the protective layer.
- Thermal Stress: Repeated heating/cooling cycles above 900°C may cause carbide precipitation. 316L (low-carbon variant) is recommended for welded assemblies.
Identification & Marking
- Laser Etching: Permanent markings include grade (316/316L), ASTM standard, heat number, and stainless steel pipe diameters.
- Color Coding: Red bands for high-temperature variants (316) and blue for low-carbon (316L) pipes.
