What is ERTi-24?
ERTi-24 is a palladium-modified Ti-6Al-4V filler wire to ASTM B863 that matches Grade 24 base metal, combining alpha-beta strength with the crevice-corrosion behaviour of Pd-bearing titanium. It is chosen for high-strength weldments in reducing acids, hot chlorides and offshore service, and is supplied as TIG cut lengths and spooled wire. Deposits give 860 MPa yield, 930 MPa tensile, 10% elongation and 330 HB, with a 350 °C service limit and a corrosion score of 94. The Pd addition raises cost and availability is limited; use ERTi-5 or ERTi-23 where the extra corrosion margin is not needed. ERTi-24 has a density of 4.43 g/cm³ (0.16 lb/in³), lighter than 89% of titanium grades. It melts at 1,604°C (2,919 °F). ERTi-24 has a yield strength of 860 MPa (125 ksi) and a tensile strength of 930 MPa (135 ksi) — stronger than 71% of titanium grades. Elongation at break is 10% and the elastic modulus is 114 GPa (16.5 Msi).

Working with ERTi-24
Is ERTi-24 easy to machine?
Rarely machined as wire; if the deposit is machined use rigid setups, sharp uncoated-carbide or PVD-coated tools, low surface speed (25–50 m/min) and flood coolant to avoid work hardening and titanium fire risk.
Can ERTi-24 be welded?
GTAW/GMAW/PAW with high-purity argon torch, trailing and back purge (<50 ppm O₂); keep interpass below ~150 °C, clean wire with acetone, and avoid any contamination that raises O/N/H and embrittles the bead.
Can ERTi-24 be formed, bent or molded?
Wire is supplied straightened or spooled; cold bending of the deposit is limited — bend radii ≥4t and prefer warm forming at 200–400 °C for weldment straightening.
ERTi-24 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on ERTi-24?
Pickle in HNO₃/HF or use abrasive/stainless brushing to remove alpha case and heat tint before service; Type II anodizing or glass-bead peening are used for appearance and fatigue improvement.

ERTi-24 — frequently asked
What is ERTi-24 used for?
ERTi-24 is typically used for chemical process equipment welding, marine and offshore titanium fabrication and high-strength corrosion-resistant weldments. In short: pd-modified Ti-6Al-4V filler; strength plus acid resistance; matches Grade 24 base metal.
What is the yield strength of ERTi-24?
ERTi-24 has a typical yield strength of 860 MPa (125 ksi) and a tensile strength of 930 MPa (135 ksi) — stronger than 71% of titanium grades. Strength varies by condition: see the 4 listed tempers.
Is ERTi-24 easy to machine?
Not especially — machinability is rated poor (20/100, worse than 68% of titanium grades). Rarely machined as wire; if the deposit is machined use rigid setups, sharp uncoated-carbide or PVD-coated tools, low surface speed (25–50 m/min) and flood coolant to avoid work hardening and titanium fire risk.
Can ERTi-24 be welded?
Yes — weldability is rated very good (80/100). GTAW/GMAW/PAW with high-purity argon torch, trailing and back purge (<50 ppm O₂); keep interpass below ~150 °C, clean wire with acetone, and avoid any contamination that raises O/N/H and embrittles the bead.

What is the maximum service temperature of ERTi-24?
ERTi-24 is rated for continuous use to about 350°C (662 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ERTi-24-AW and ERTi-24-STA?
AW is the default condition — default condition for filler-metal property reporting: all-weld-metal deposited under inert shielding with no PWHT. STA: used only where the whole weldment is heat treated with the Grade 24 base metal for higher strength; ductility and weld-zone toughness drop. Yield strength is 860 MPa in AW versus 1,020 MPa in STA.
How much does ERTi-24 cost?
ERTi-24 is a high-cost titanium ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
