What is Ti Grade 11?
Ti Grade 11 (R52250, 3.7225) is Grade 1 chemistry with about 0.15 % palladium, covered by ASTM B265/B348. It combines the ductility and formability of Grade 1 (32 % elongation, formability score 90) with enhanced crevice-corrosion resistance for demanding chemical service, and is used as thin sheet, strip, tube and deep-drawn or roll-formed parts. Strength is the lowest in the family at 210 MPa yield and 300 MPa tensile, service is limited to 300 °C, and the palladium addition raises cost. Choose Grade 7 when the same corrosion resistance is needed at higher strength, or Grade 1 when crevice attack is not a concern. Ti Grade 11 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). Ti Grade 11 has a yield strength of 210 MPa (30.5 ksi) and a tensile strength of 300 MPa (43.5 ksi) — weaker than 99% of titanium grades. Elongation at break is 32% and the elastic modulus is 103 GPa (14.9 Msi).

Working with Ti Grade 11
Is Ti Grade 11 easy to machine?
Machine like CP Ti: low speed, heavy positive-rake sharp carbide, high feed and flood coolant to avoid galling, work hardening and chip fires.
Can Ti Grade 11 be welded?
Excellent GTAW/PAW/EBW weldability with trailing-shield and back-purge argon; keep the weld and HAZ below ~200 ppm oxygen pick-up (bright silver bead) and never weld in air.
Can Ti Grade 11 be formed, bent or molded?
Best cold formability of the CP grades — bend radii of ~2t are routine; allow for high springback or warm-form at 150–300 °C.
Ti Grade 11 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 Ti Grade 11?
Pickle in HNO3/HF to remove alpha case and scale, then passivate; colour anodizing and electropolishing both work well, plating is rarely used.

Ti Grade 11 — frequently asked
What is Ti Grade 11 used for?
Ti Grade 11 is typically used for chemical process piping, pressure vessels needing forming and corrosion resistance and desalination equipment. In short: most formable CP-family grade; grade 1 ductility with Pd corrosion resistance; lowest strength in family.
What is the yield strength of Ti Grade 11?
Ti Grade 11 has a typical yield strength of 210 MPa (30.5 ksi) and a tensile strength of 300 MPa (43.5 ksi) — weaker than 99% of titanium grades. Strength varies by condition: see the 5 listed tempers.
Is Ti Grade 11 easy to machine?
Not especially — machinability is rated fair (38/100, better than 85% of titanium grades). Machine like CP Ti: low speed, heavy positive-rake sharp carbide, high feed and flood coolant to avoid galling, work hardening and chip fires.
Can Ti Grade 11 be welded?
Yes — weldability is rated excellent (90/100). Excellent GTAW/PAW/EBW weldability with trailing-shield and back-purge argon; keep the weld and HAZ below ~200 ppm oxygen pick-up (bright silver bead) and never weld in air.

Best cold formability of the CP grades — bend radii of ~2t are routine; allow for high springback or warm-form at 150–300 °C.
What is the maximum service temperature of Ti Grade 11?
Ti Grade 11 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 11-ANN and Ti Grade 11-CW?
ANN is the default condition — standard stocked condition for corrosion service: maximum ductility and formability, meets ASTM B265/B338/B348 Grade 11. CW: choose when higher strength and straightness are needed and forming is finished; ductility drops sharply. Yield strength is 210 MPa in ANN versus 410 MPa in CW.
