2. Key Advantages of Ti31 Powder
Ti31 titanium alloy powder is a purpose-engineered near-α titanium alloy optimized for corrosion-resistant structural components in moderate-temperature industrial environments. Its advantages include:
- Outstanding Ductility at Elevated Temperatures: Elongation remains ≥20% at both 250°C and 350°C—significantly higher than Ti-6Al-4V (~8–12% at 300°C)—making it ideal for parts subject to thermal cycling or impact loading.
- Enhanced Corrosion Resistance via Nickel Addition: The controlled Ni content (0.3–1.0%) improves resistance to pitting and crevice corrosion, especially in chloride-rich environments (e.g., seawater, chemical processing), without compromising weldability.
- Excellent AM Processability: Particle size (D₅₀ = 30–40 μm), high sphericity (≥0.9), and low flow time (≤35 s/50g) ensure reliable powder spreading and dense, homogeneous builds in SLM systems—meeting ASTM and ISO requirements.
- Balanced Strength–Toughness Profile: At room temperature: ≥720 MPa UTS, ≥650 MPa YS, with >16% elongation—superior to Grade 7 in ductility and comparable to Grade 12 but with higher strength.
- Low Interstitial Content: Ultra-low hydrogen (≤0.008%) and oxygen (≤0.15%) minimize embrittlement risk and support consistent mechanical performance.
In essence, Ti31 fills a critical niche: a cost-effective, high-ductility, corrosion-resistant titanium powder for industrial AM applications where Ti-64 is over-specified and pure Ti lacks strength.
3. Additive Manufacturing Application
Ti31 titanium alloy powder is specifically formulated for SLM-based additive manufacturing of corrosion-critical industrial components, including heat exchangers, condensers, valves, pump housings, and pipeline fittings. Its tightly controlled particle size distribution (D₁₀ ≥15 μm, D₅₀ = 30–40 μm, D₉₀ ≤63 μm), high sphericity (≥0.9), and excellent flowability (≤35 s/50g) enable stable recoating and high-density part fabrication (>99.3% relative density) with minimal porosity or balling. The alloy’s unique composition delivers exceptional hot ductility (≥20% elongation at 250–350°C) and superior resistance to chloride-induced corrosion, making it ideal for marine, chemical, and energy-sector applications. Post-build heat treatment further enhances microstructural uniformity and fatigue performance, enabling certified use in demanding service environments without requiring costly post-processing.
