Cold Drawn / Hot Rolled /Forged Stainless Steel Round Rod Alloy 316Ti SSS Bar 1.4571 UNS S31635
Introduction to Alloy 316Ti Stainless Steel Round Rod
Alloy 316Ti (UNS S31635 / DIN 1.4571) is a titanium-stabilized austenitic stainless steel derived from the classic 316 alloy, enhanced with titanium additions to address intergranular corrosion challenges. This premium stainless steel round rod combines exceptional corrosion resistance, superior mechanical properties, and excellent high-temperature performance, making it a preferred choice for critical applications across industries worldwide. Available in three primary processing forms—cold drawn, hot rolled, and forged—316Ti round rods cater to diverse project requirements, from precision engineering to heavy-duty industrial use.
Titanium stabilization is the defining feature of 316Ti, as it forms titanium carbides during heat treatment, preventing the formation of chromium carbides that cause sensitization at temperatures between 425°C and 815°C (900°F to 1500°F) . This stabilization ensures the alloy maintains its corrosion resistance even after welding or prolonged exposure to elevated temperatures, outperforming standard 316 in harsh environments. With a density of 7.99 g/cm³ (0.286 lb/in³) and excellent formability, 316Ti round rods balance structural integrity with processing versatility .
Key Processing Methods: Cold Drawn vs. Hot Rolled vs. Forged
1. Cold Drawn 316Ti Round Rod
Cold drawn 316Ti round rods are manufactured by pulling hot rolled bars through precision dies at room temperature, resulting in exceptional dimensional accuracy and surface finish. This process enhances mechanical properties through strain hardening, delivering higher tensile strength and improved machinability compared to hot rolled alternatives .
Key Characteristics:
- Surface Finish: Bright, smooth (Ra 8-16 microinches) with a mirror-like appearance, eliminating the need for secondary polishing
- Dimensional Tolerance: Tight control (±0.002" to ±0.005") for precision applications
- Mechanical Strength: 10-15% higher tensile strength and 15-25% greater load-bearing capacity than hot rolled 316Ti
- Applications: Precision engineering components, medical devices, electronic equipment, and aerospace parts requiring strict dimensional compliance
2. Hot Rolled 316Ti Round Rod
Hot rolled 316Ti round rods are produced by heating the alloy above its recrystallization temperature (≥1700°F / 926°C) and rolling it into cylindrical shapes. This cost-effective process offers high production efficiency, making it ideal for large-volume orders and applications where surface finish and tight tolerances are not critical .
Key Characteristics:
- Surface Finish: Rough, scaled surface due to oxidation during heating, requiring grinding or machining for precision use
- Dimensional Tolerance: Wider range (±0.030" or more) compared to cold drawn
- Mechanical Strength: Lower tensile strength than cold drawn but excellent ductility and weldability
- Cost-Effectiveness: 20-30% more affordable than cold drawn options, suitable for structural applications
- Applications: Construction framing, industrial machinery, storage tanks, and general engineering projects
3. Forged 316Ti Round Rod
Forged 316Ti round rods are created through hot forging, where the alloy is heated and shaped under high pressure using dies or hammers. This process refines the grain structure, enhancing toughness, fatigue resistance, and impact strength, making it suitable for heavy-duty applications.
Key Characteristics:
- Structural Integrity: Uniform grain structure with minimal porosity, ensuring reliability in high-stress environments
- Customization: Capable of producing large diameters (up to 500mm) and custom lengths for specialized projects
- Mechanical Performance: Superior creep and stress-rupture resistance at elevated temperatures
- Applications: Offshore oil drilling equipment, power generation components, chemical reactors, and pressure vessels
