Mechanical & Chemical Properties
Tensile Strength
Our stainless steel rod stock achieves tensile strengths up to 1,200 MPa (Duplex 2205), ideal for heavy-load applications such as offshore rigs and chemical processing plants. The 316L grade (520–860 MPa) incorporates 2–3% molybdenum for superior chloride resistance, making it perfect for coastal installations like stainless steel shower curtain rods in humid bathrooms. Precipitation-hardened grades like 17-4 PH (700–1,000 MPa) are heat-treatable for aerospace components requiring precision and stability.
Bend Strength
Bend strength ranges from 60–75% of tensile strength, optimized for dynamic loads. For example, stainless steel rod home depot-compatible threaded rods (A4-70 grade) exhibit bend resistance of 310–430 MPa, ensuring reliability in structural applications like bridges and solar panel mounts. Cold-drawn 304 rods achieve 30% higher bend resistance than annealed grades, critical for machinery components exposed to vibration.
Identification & Marking
Stainless steel rods are labeled per global standards:
- ASTM A276: Specifies chemical compositions (e.g., 304: 18% Cr, 8% Ni).
- ISO 15510: Ensures traceability for marine and medical applications.
- Laser Etching: Permanent markings include grade (e.g., "316L-860MPa"), batch number, and tensile class.
Weight Calculation
Weight (kg) = Volume (m³) × Density (7,930 kg/m³ for austenitic steel).
Example for a 10mm diameter, 1m rod:π × (0.005m)² × 1m × 7,930 kg/m³ ≈ 0.62 kg.
For stainless steel shower curtain rods (16mm diameter):Weight ≈ 1.58 kg/m. Custom weights vary based on alloy density and surface treatments.
Why Stainless Steel Rusts: Causes & Solutions
While stainless steel resists corrosion via a chromium oxide layer (≥10.5% Cr), specific conditions trigger rust:
- Chloride Exposure: Saltwater or cleaning agents degrade passive layers. Use 316L for stainless steel shower curtain rods in coastal areas.
- Galvanic Corrosion: Contact with carbon steel accelerates oxidation. Insulate metals using dielectric coatings or stainless steel rod stock with ER309L welding rods.
- Mechanical Damage: Scratches expose iron. Passivate surfaces with nitric acid post-machining to restore chromium oxide layers.
- Low Oxygen Environments: Stagnant water in crevices (e.g., threaded joints) breeds crevice corrosion. Design gaps >0.5mm for oxygen flow.
