Working with Ti Grade 17 CW-SR
Is Ti Grade 17 easy to machine?
Machine like CP titanium: rigid setup, sharp uncoated-carbide or PVD tools, low surface speed (~30–50 m/min), heavy positive rake, generous chlorine-free flood coolant to avoid galling and chip welding.
Can Ti Grade 17 be welded?
Excellent GTAW/plasma/EB weldability with full argon shielding of pool, root and hot zone; keep interpass clean and below ~150 °C, target silver/straw weld colour, and use matching Gr.17/Gr.1 filler (ERTi-1 acceptable but loses the Pd benefit in the bead).
Can Ti Grade 17 be formed, bent or molded?
Very formable cold — deep drawing, roll bending and spinning are routine; allow generous springback (~15–25°), bend radii ≥2t for sheet, and use non-galling lubricants or PE film; hot form 480–650 °C for severe shapes.
What surface finishes work on Ti Grade 17?
Pickle in HNO3/HF after hot work to remove alpha case; grit-blast plus passivation for vessel linings; colour or hard anodising is available, and no plating/paint is normally needed because the oxide film is self-healing.

Ti Grade 17 CW-SR — frequently asked
What is Ti Grade 17 CW-SR used for?
Ti Grade 17 CW-SR is typically used for deep-drawn chemical equipment, desalination components and piping systems. In short: most formable Pd-bearing grade; deep-draw crevice-resistant titanium; low strength, high ductility.
What is the yield strength of Ti Grade 17 CW-SR?
Ti Grade 17 CW-SR has a typical yield strength of 380 MPa (55.1 ksi) and a tensile strength of 450 MPa (65.3 ksi) — weaker than 73% of titanium grades. Strength varies by condition: see the 3 listed tempers.
Is Ti Grade 17 CW-SR easy to machine?
Reasonably — machinability is rated fair (45/100, better than 100% of titanium grades). Machine like CP titanium: rigid setup, sharp uncoated-carbide or PVD tools, low surface speed (~30–50 m/min), heavy positive rake, generous chlorine-free flood coolant to avoid galling and chip welding.
Can Ti Grade 17 CW-SR be welded?
Yes — weldability is rated very good (80/100). Excellent GTAW/plasma/EB weldability with full argon shielding of pool, root and hot zone; keep interpass clean and below ~150 °C, target silver/straw weld colour, and use matching Gr.17/Gr.1 filler (ERTi-1 acceptable but loses the Pd benefit in the bead).
What surface finishes work on Ti Grade 17 CW-SR?
Pickle in HNO3/HF after hot work to remove alpha case; grit-blast plus passivation for vessel linings; colour or hard anodising is available, and no plating/paint is normally needed because the oxide film is self-healing.
Can Ti Grade 17 CW-SR be formed, bent or molded?
Very formable cold — deep drawing, roll bending and spinning are routine; allow generous springback (~15–25°), bend radii ≥2t for sheet, and use non-galling lubricants or PE film; hot form 480–650 °C for severe shapes.
What is the maximum service temperature of Ti Grade 17 CW-SR?
Ti Grade 17 CW-SR 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 17 Annealed and Ti Grade 17 CW-SR?
Annealed is the default condition — standard stocked condition: maximum ductility and formability for linings, tube and drawn parts. CW-SR: pick when higher strength and tighter tolerances are needed in small-diameter bar or tubing at the cost of ductility. Yield strength is 230 MPa in Annealed versus 380 MPa in CW-SR.
