Performance Attributes
Tensile & Bending Strength
Our stainless steel rod bar China products are engineered for demanding applications. AISI 410 (750–950 MPa tensile strength) excels in high-stress environments like automotive axles and industrial fasteners. The stainless steel round bar steel rod in AISI 201 (650–750 MPa) offers a cost-effective solution for decorative frameworks and indoor structures, while AISI 430 (450–600 MPa) balances affordability with moderate corrosion resistance for HVAC and food processing equipment.
Identification & Traceability
Each stainless steel rod bar China is laser-etched with a unique identifier (e.g., "430-Ø50x6M") that includes grade, diameter, and batch number. This aligns with ASTM/JIS standards and simplifies quality control for projects requiring precision, such as stainless steel square bar rod assemblies in architectural facades.
Weight Calculation
Calculate the weight of a stainless steel round bar steel rod using:
- AISI 201/304: Density = 7.93 g/cm³ → A 50 mm rod weighs 15.5 kg/m.
- AISI 430: Density = 7.70 g/cm³ → A 50 mm rod weighs 15.1 kg/m.
Why Stainless Steel Can Rust
Despite its corrosion resistance, stainless steel rod bar China may rust under specific conditions:
- Chloride Exposure: Prolonged contact with seawater or de-icing salts can degrade the passive chromium oxide layer, particularly in AISI 430 (lower nickel content).
- Galvanic Corrosion: Direct contact with carbon steel in humid environments accelerates oxidation. Use insulating materials for stainless steel square bar rod in mixed-metal assemblies.
- Surface Contamination: Iron particles from machining tools can embed into stainless steel, causing localized rust. Passivation (nitric acid treatment) restores corrosion resistance.
Manufacturing & Processing
- Cold Rolling: Precision cold rolling ensures ±0.05 mm tolerance for stainless steel round bar steel rod, optimized for CNC machining and tool calibration.
- Heat Treatment: AISI 410 undergoes quenching and tempering to achieve hardness up to 240 HV, ideal for wear-resistant components like valve stems.
- Surface Finishing: Electropolishing (for AISI 201) reduces surface roughness (Ra ≤0.4 μm), minimizing bacterial adhesion in food processing.
Applications
- Automotive Engineering: Stainless steel rod bar China (AISI 410) for high-strength crankshafts and exhaust systems.
- Industrial Fabrication: Stainless steel square bar rod (AISI 430) for structural frameworks in chemical plants.
