Mechanical & Chemical Properties
Tensile Strength
Tensile strength measures a material’s resistance to breaking under tension. Our stainless steel drapery rods and structural-grade rods (e.g., A4-70) achieve tensile strengths up to 1000 MPa, ensuring reliability in high-stress applications like bridges, solar installations, and heavy machinery. Austenitic grades (304/316) offer balanced strength (520–860 MPa) with superior ductility.
Bend Strength
Bend strength reflects resistance to deformation under load. Stainless steel square rod exhibits bend strengths 60–70% of tensile strength due to its uniform cross-section, ideal for architectural frameworks. For stainless steel ground rod, cold-working enhances bend resistance by up to 30%.
Identification & Marking
Stainless steel rods are labeled per international standards:
- ASTM A276: Denotes hot-rolled bars (e.g., 304, 316).
- DIN 976-1: Specifies threaded rods (A2/A4 grades).
- ISO 3506: Corrosion-resistant fasteners (A2/A4-70).
Laser etching or embossing ensures traceability of material grade, batch number, and manufacturer.
Weight Calculation
Weight (kg) = Volume (m³) × Density (7930 kg/m³ for austenitic steel).
Example for a 10mm diameter, 1m round rod:π × (0.005m)² × 1m × 7930 kg/m³ ≈ 0.62 kg.
Custom stainless steel square rod weights vary based on side length and alloy density.
Why Stainless Steel Rusts: Causes & Solutions
While stainless steel resists corrosion via a chromium oxide layer, specific conditions trigger rust:
- Chloride Exposure: Saltwater or de-icing salts degrade passive layers, causing pitting. Use 316/L (with 2–3% Mo) for coastal or chemical environments.
- Galvanic Corrosion: Contact with carbon steel or copper accelerates oxidation. Insulate dissimilar metals.
- Mechanical Damage: Scratches or welding defects expose underlying iron. Passivate surfaces post-fabrication.
- Low Oxygen Environments: Stagnant water in crevices (e.g., threaded joints) breeds crevice corrosion. Design gaps >0.5mm to allow oxygen flow.
