Technical Properties
Tensile & Bend Strength
Our stainless steel exhaust elbows are engineered for high-pressure industrial systems. The tensile strength of 316L-grade elbows exceeds 860 MPa, ensuring structural integrity in corrosive environments like chemical plants or marine exhaust systems. Bend strength is optimized through cold-forming processes, achieving a 1.5D–3D radius for smooth fluid flow and reduced turbulence. For 5 inch 90 degree exhaust elbow stainless steel, wall thickness (SCH40 or higher) and mandrel-bending techniques prevent deformation under extreme thermal cycling.
Weight Calculation
Calculate elbow weight using:
Example: A 5 inch 90 degree exhaust elbow (SCH40, 114mm diameter, 6mm wall thickness) weighs ~1.2 kg.
Identification Methods
- Laser Etching: ASTM/EN codes (e.g., "316L" or "ASTM A403") for traceability.
- QR Codes: Linked to mill test reports (MTRs) with chemical composition and heat treatment data.
Why Stainless Steel Rusts & Prevention
While stainless steel elbows resist rust due to their chromium oxide layer (≥10.5% Cr), specific conditions trigger corrosion:
- Chloride Exposure: Coastal or industrial environments cause pitting in 5 inch 90 degree exhaust elbow stainless steel if passivation is incomplete.
- Mechanical Damage: Scratches on polished surfaces expose the base metal. Use non-abrasive cleaning tools.
- Galvanic Corrosion: Contact with carbon steel or aluminum in stainless steel exhaust elbows accelerates degradation. Isolation gaskets are recommended.
- Organic Contaminants: Food residues or pollutants degrade the passive layer. Clean biweekly with pH-neutral solutions.
Prevention Tips:
- Post-installation passivation with nitric acid.
- Avoid chloride-based cleaners.
- Regular visual inspections for surface defects.
Applications
- Industrial Exhausts: stainless steel exhaust elbows for automotive, marine, and HVAC systems.
- Chemical Processing: 316L-grade elbows for acid/alkali transport.
- Food & Pharma: 3A-certified stainless steel elbow with electro-polished interiors for hygiene.
