Technical Properties
Tensile & Bend Strength
Our stainless steel 90 degree elbow 1 2 is engineered for high-pressure systems, with tensile strength exceeding 860 MPa for 316L variants, ideal for corrosive environments like marine exhausts or chemical plants. The bend strength is enhanced using mandrel-forming techniques to prevent wall thinning and maintain structural integrity under thermal cycling. For stainless steel 45 elbow designs, cold-rolled grades achieve 1.5D–3D radii, reducing turbulence and pressure drop in HVAC or pharmaceutical pipelines.
Weight Calculation
Calculate elbow weight using:
Example: A stainless steel 45 degree elbow dimensions (SCH40, 2" diameter, 4mm wall thickness) weighs ~0.85 kg.
Identification Methods
- Laser Etching: ASTM/EN codes (e.g., "316L" or "ASME B16.9") 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 resists rust through its chromium oxide layer (≥10.5% Cr), specific conditions compromise protection:
- Chloride Exposure: Coastal or industrial environments trigger pitting in stainless steel 45 elbow if passivation is incomplete.
- Mechanical Damage: Scratches on mirror-polished surfaces expose the base metal. Use non-abrasive cleaning tools.
- Galvanic Corrosion: Contact with carbon steel or aluminum 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.
