Technical Properties
Tensile Strength
The stainless steel long radius elbow exhibits exceptional tensile strength ranging from 515 MPa to 860 MPa, depending on the alloy grade. This ensures resistance to deformation under extreme pressure, making it ideal for high-stress environments like oil refineries or stainless steel marine exhaust elbows systems.
Bending Strength
Engineered for smooth fluid dynamics, the elbow’s forged construction minimizes turbulence and maintains structural integrity under cyclic loading. Its bending strength exceeds 350 MPa, validated by third-party hydrostatic tests.
Weight Calculation Formula
Calculate the approximate weight using:
Weight (kg) = (OD - WT) × WT × 0.02466 × Length (mm)
(OD = Outer Diameter, WT = Wall Thickness)
Identification & Marking
Each elbow is laser-etched with:
- Material Grade (e.g., 316L)
- Size & Thickness (e.g., 5" SCH40)
- Certification Stamp (ASME B16.9, DIN 2605)
- Batch Number for traceability.
Why Stainless Steel Elbows Resist Rust?
While stainless steel is inherently corrosion-resistant, improper handling or harsh environments can cause localized rust. Key factors include:
- Chloride Exposure: Prolonged contact with seawater or de-icing salts may breach the passive chromium oxide layer.
- Galvanic Corrosion: Contact with dissimilar metals (e.g., carbon steel) in conductive environments.
- Surface Contamination: Iron particles from tools or grinding can initiate oxidation.
- Low Oxygen Environments: Stagnant water or crevices may reduce self-healing of the oxide layer.
Regular cleaning with pH-neutral solutions and avoiding abrasive tools ensures longevity.
