Ti Grade 13-HR has a yield strength of 220 MPa (31.9 ksi) and a tensile strength of 330 MPa (47.9 ksi) — weaker than 97% of titanium grades. Elongation at break is 28% and the elastic modulus is 105 GPa (15.2 Msi). Ti Grade 13-HR has a density of 4.51 g/cm³ (0.163 lb/in³), heavier than 57% of titanium grades. It melts at 1,660°C (3,020 °F). Annealed is the default condition FabDigit quotes; HR is available on request or by drawing note.

Working with Ti Grade 13-HR
Is Ti Grade 13 easy to machine?
Machine like CP Ti: rigid setups, sharp uncoated-carbide or coated inserts, low surface speed (~30–50 m/min), heavy positive feed and copious flood coolant to avoid work hardening, galling and chip fires.
Can Ti Grade 13 be welded?
Excellent GTAW/PAW/EBW weldability with matching or CP Ti filler, but requires full inert-gas shielding of the pool, trailing gas and back purge; keep oxygen/nitrogen pickup low and clean surfaces to bright metal.
Can Ti Grade 13 be formed, bent or molded?
Low interstitial content gives good cold formability — bend radii around 2–3 t for annealed sheet; use generous radii, slow strain rates, and warm forming (200–400 °C) for severe draws, allowing for high springback.
What surface finishes work on Ti Grade 13?
Pickle in HNO3/HF after hot work to remove alpha case, then descale, bead-blast or polish; colour anodising and Ti-nitride/oxide treatments help against galling since Ti is prone to seizing on itself.

Ti Grade 13-HR — frequently asked
What is Ti Grade 13-HR used for?
Ti Grade 13-HR is typically used for offshore and subsea components, seawater piping and chemical process equipment requiring high toughness. In short: toughest of the Ti-Ni-Ru alloys; low-interstitial, high ductility; better crevice resistance than CP Ti.
What is the yield strength of Ti Grade 13-HR?
Ti Grade 13-HR has a typical yield strength of 220 MPa (31.9 ksi) and a tensile strength of 330 MPa (47.9 ksi) — weaker than 97% of titanium grades. Strength varies by condition: see the 4 listed tempers.
Is Ti Grade 13-HR easy to machine?
Not especially — machinability is rated fair (37/100, better than 82% of titanium grades). Machine like CP Ti: rigid setups, sharp uncoated-carbide or coated inserts, low surface speed (~30–50 m/min), heavy positive feed and copious flood coolant to avoid work hardening, galling and chip fires.
Can Ti Grade 13-HR be welded?
Yes — weldability is rated excellent (88/100). Excellent GTAW/PAW/EBW weldability with matching or CP Ti filler, but requires full inert-gas shielding of the pool, trailing gas and back purge; keep oxygen/nitrogen pickup low and clean surfaces to bright metal.
What surface finishes work on Ti Grade 13-HR?
Pickle in HNO3/HF after hot work to remove alpha case, then descale, bead-blast or polish; colour anodising and Ti-nitride/oxide treatments help against galling since Ti is prone to seizing on itself.
Can Ti Grade 13-HR be formed, bent or molded?
Low interstitial content gives good cold formability — bend radii around 2–3 t for annealed sheet; use generous radii, slow strain rates, and warm forming (200–400 °C) for severe draws, allowing for high springback.
What is the maximum service temperature of Ti Grade 13-HR?
Ti Grade 13-HR is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Ti Grade 13 Annealed and Ti Grade 13 CW-SR?
Annealed is the default condition — default stocked condition: maximum ductility and toughness for forming, welding and corrosion service. CW-SR: choose when higher yield strength and springback control are needed in thin sheet, wire or tubing; ductility drops markedly. Yield strength is 210 MPa in Annealed versus 400 MPa in CW-SR.
