Titanium Grade 2 Verified Reference Properties
Commercially pure Titanium Grade 2 is specified for extreme corrosion resistance, balanced ductility, and clean biocompatibility. Below are verified mechanical and physical benchmarks per ASTM standards.
| Property | Reference Value | Standard Basis & Engineering Notes |
|---|---|---|
| Density | 4.51 g/cm³ | Typical commercially pure Titanium Grade 2; ~45% lighter than stainless steel |
| Tensile Strength | ≥ 345 MPa | ASTM B265 / ASTM B348 minimum standard for wrought sheet, plate, and bar |
| Yield Strength (0.2% offset) | ≥ 275 MPa | Standard minimum requirement; evaluated per ASTM E8/E8M standard test methods |
| Hardness | ≤ 200 HB (Approx.) | Product reference limit; verified via calibrated Rockwell / Brinell testing systems |
| Elongation at Break | ≥ 20% | Demonstrates superior cold-forming and ductilization capacity versus Ti-6Al-4V |
| Thermal Conductivity | ~ 16.4 W/(m·K) at 20°C | Low thermal transfer characteristic; critical parameter for cutting speed and heat control |
Mastering Heat and Tool Wear in Grade 2 Titanium
Titanium Grade 2 possesses low thermal conductivity (~16.4 W/m·K). Unlike aluminum or carbon steel where cutting heat evacuates largely via the chips, over 80% of heat generated during Grade 2 titanium CNC machining concentrates right at the cutting interface.
Uncontrolled cutting zone temperatures lead directly to work hardening, rapid tool chipping, built-up edge (BUE), and micro-dimensional drift. Our dedicated machining protocols isolate and neutralize these risks:
High-Pressure Targeted Coolant Delivery
High-pressure through-spindle cooling directed straight at the tool-workpiece interface prevents chip welding and breaks vapor barriers, keeping cutting edges within safe thermal thresholds.
Climb Milling & Controlled Radial Engagement
We employ dynamic trochoidal toolpaths with reduced radial immersion to minimize contact time, enabling efficient heat dissipation into the chip stream without tool rubbing.
Sharp Positive Rake Tooling
Custom polished micro-grain solid carbide tools with optimized coating systems reduce friction coefficients and eliminate the localized galling typical of commercially pure titanium.
Surface Roughness & Mechanical Integrity
In fluid-handling, medical, and chemical systems, surface finish directly determines seal effectiveness and corrosion longevity. We separate roughing, semi-finishing, and final sizing passes to relieve internal stresses before generating critical sealing lands.
Achieved on precision 5-axis surfaces and turned diameters via optimized wiper inserts and constant surface speed control.
Internal cylindrical grinding and honing provide bore cylindricity down to 0.005 mm for hydraulic and valve applications.
Elimination of Burr and Recutting Risks
Titanium Grade 2 is ductile and prone to burr accumulation on intersecting hole exits. We implement synchronized CNC deburring paths and microscopic tool-edge verification to guarantee 100% burr-free fluid passages and manifold ports.

Applications for Titanium Grade 2 Parts
Select a sector to explore how commercially pure Grade 2 titanium solves demanding structural, corrosive, and weight challenges.
Severe Chemical & Marine Environments
Grade 2 titanium exhibits passive oxide film resilience in oxidizing acid solutions, wet chlorine, chloride salts, and seawater. It replaces stainless steel where pitting and stress-corrosion cracking cause premature failures.
- ✓ Chemical pump housings and impellers
- ✓ Water desalination & chlorination manifolds
- ✓ Heat-exchanger flanges and tube sheets
Engineering Tip
For flanged connection interfaces, our Mazak horizontal milling machines maintain face flatness within 0.015 mm to ensure bubble-tight elastomer or PTFE gasket sealing in acid-distribution lines.
