What is Ti Grade 14 HR-ANN?
Ti Grade 14 HR-ANN is Ti Grade 14 supplied in the HR-ANN condition — standard condition for thick plate and pressure-vessel clad/lining stock where section size precludes cold work. Ti Grade 14 HR-ANN has a yield strength of 345 MPa (50 ksi) and a tensile strength of 470 MPa (68.2 ksi) — weaker than 80% of titanium grades. Elongation at break is 24% and the elastic modulus is 103 GPa (14.9 Msi). Ti Grade 14 HR-ANN has a density of 4.51 g/cm³ (0.163 lb/in³), heavier than 57% of titanium grades. It melts at 1,650°C (3,002 °F). Annealed is the default condition FabDigit quotes; HR-ANN is available on request or by drawing note.

Working with Ti Grade 14 HR-ANN
Is Ti Grade 14 easy to machine?
Machine like CP Ti Grade 2: low surface speed (25–45 m/min carbide), heavy positive rake, high feed, flood coolant and sharp tools to avoid work hardening, galling and chip fires.
Can Ti Grade 14 be welded?
Excellent GTAW/GMAW/plasma/EB weldability with matching or Gr.2 filler, but requires full inert-gas trailing and back-purge below 200 °C to keep welds ductile and prevent contamination.
Can Ti Grade 14 be formed, bent or molded?
Cold form with generous bend radii (≈3–4 t) and allow for high springback; warm forming at 200–300 °C markedly improves severe draws.
What surface finishes work on Ti Grade 14?
Pickle in HNO3/HF to remove alpha case and scale; can be anodised for colour/identification, and is normally used bare since the native oxide provides the corrosion protection.

Ti Grade 14 HR-ANN — frequently asked
What is Ti Grade 14 HR-ANN used for?
Ti Grade 14 HR-ANN is typically used for chemical process vessels, offshore piping and heat exchangers. In short: mid-strength Ti-Ni-Ru alloy; strength-toughness balance; 315 °C service ceiling.
What is the yield strength of Ti Grade 14 HR-ANN?
Ti Grade 14 HR-ANN has a typical yield strength of 345 MPa (50 ksi) and a tensile strength of 470 MPa (68.2 ksi) — weaker than 80% of titanium grades. Strength varies by condition: see the 4 listed tempers.
Is Ti Grade 14 HR-ANN easy to machine?
Not especially — machinability is rated poor (33/100, better than 74% of titanium grades). Machine like CP Ti Grade 2: low surface speed (25–45 m/min carbide), heavy positive rake, high feed, flood coolant and sharp tools to avoid work hardening, galling and chip fires.
Can Ti Grade 14 HR-ANN be welded?
Yes — weldability is rated excellent (85/100). Excellent GTAW/GMAW/plasma/EB weldability with matching or Gr.2 filler, but requires full inert-gas trailing and back-purge below 200 °C to keep welds ductile and prevent contamination.
What surface finishes work on Ti Grade 14 HR-ANN?
Pickle in HNO3/HF to remove alpha case and scale; can be anodised for colour/identification, and is normally used bare since the native oxide provides the corrosion protection.
Can Ti Grade 14 HR-ANN be formed, bent or molded?
Cold form with generous bend radii (≈3–4 t) and allow for high springback; warm forming at 200–300 °C markedly improves severe draws.
What is the maximum service temperature of Ti Grade 14 HR-ANN?
Ti Grade 14 HR-ANN is rated for continuous use to about 315°C (599 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Ti Grade 14 Annealed and Ti Grade 14 CW-SR?
Annealed is the default condition — standard stocked condition for all corrosion-service product forms; best ductility, formability and weld response. CW-SR: pick when higher yield strength and tighter tolerances are needed on small-diameter bar or tube and forming is not required. Yield strength is 360 MPa in Annealed versus 540 MPa in CW-SR.
