Working with Ti Grade 14 CW-SR
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 CW-SR — frequently asked
What is Ti Grade 14 CW-SR used for?
Ti Grade 14 CW-SR 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 CW-SR?
Ti Grade 14 CW-SR has a typical yield strength of 540 MPa (78.3 ksi) and a tensile strength of 620 MPa (89.9 ksi) — weaker than 58% of titanium grades. Strength varies by condition: see the 4 listed tempers.
Is Ti Grade 14 CW-SR easy to machine?
Not especially — machinability is rated fair (36/100, better than 82% 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 CW-SR be welded?
Yes — weldability is rated very good (80/100). 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 CW-SR?

Can Ti Grade 14 CW-SR 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 CW-SR?
Ti Grade 14 CW-SR 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.
