Mechanical & Chemical Properties
Tensile Strength
The 1 2 stainless steel threaded rod (304 grade) achieves tensile strengths of 520–860 MPa, ideal for structural applications like bridges and solar panel mounts. For high-temperature environments, brazing rod for stainless steel (ER309L) maintains weld integrity up to 700 MPa, preventing joint failure in mixed-metal assemblies. Duplex 2205 rods combine austenitic-ferritic microstructures to deliver 1,200 MPa tensile strength, outperforming standard grades by 40% in corrosive marine settings.
Bend Strength
Bend strength ranges from 60–75% of tensile strength, optimized for dynamic loads. For 304 stainless steel filler rod (ER308L), cold-drawn variants exhibit 30% higher bend resistance than annealed grades, critical for automotive suspensions and machinery exposed to vibration. The 1 2 stainless steel threaded rod (A4-70 grade) maintains bend resistance of 310–430 MPa, resisting deformation in seismic zones or heavy-load applications.
Identification & Marking
Stainless steel rods are labeled per global standards for traceability:
- ASTM A276: Specifies chemical compositions (e.g., 304: 18% Cr, 8% Ni).
- ISO 15510: Ensures compliance for marine and medical-grade applications.
- Laser Etching: Permanent markings include grade (e.g., "304-860MPa"), 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 1 2 stainless steel threaded rod (12mm diameter):Weight ≈ 0.89 kg/m
. Custom weights vary with alloy density (e.g., duplex 2205: 7,850 kg/m³).
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 de-icing salts degrade passive layers. Use 316L rods with molybdenum for marine-grade brazing rod for stainless steel in coastal infrastructure.
- Galvanic Corrosion: Contact with carbon steel accelerates oxidation. Insulate joints using dielectric coatings or 304 stainless steel filler rod (ER309L) for mixed-metal welding.
- 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.
