Titanium Grade 17
ASTM Grade 17 · UNS R52252
Grade 17 (UNS R52252) is a palladium-bearing commercially pure titanium built on the more ductile Grade 1 base — the low-palladium counterpart to Grade 11 for parts needing high formability plus a modest lift in corrosion resistance.

What is Grade 17?
Grade 17 (UNS R52252) is a palladium-bearing commercially pure titanium built on the more ductile Grade 1 base — the low-palladium counterpart to Grade 11 for parts needing high formability plus a modest lift in corrosion resistance. Annealed material runs 240 MPa yield, 330 MPa tensile and 32% elongation at about 120 HB (70 HRB), with service to 315 °C, and is stocked as thin sheet, welded tube, bar and forgings. It is the most formable Ti-Pd grade (formability 90) and welds readily (88), but strength is low, machinability is poor (40) and palladium keeps cost high. Grade 27 is the ruthenium-alloyed equivalent. Grade 17 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). Grade 17 has a yield strength of 240 MPa (34.8 ksi) and a tensile strength of 330 MPa (47.9 ksi) — weaker than 90% of titanium grades. Elongation at break is 32% and the elastic modulus is 103 GPa (14.9 Msi).

Working with Grade 17
Is Grade 17 easy to machine?
Cuts like soft CP Ti — use sharp, positive-rake carbide, low speed (~30–60 m/min) with heavy flood coolant; avoid dwell and rubbing which work-harden and gall the gummy surface.
Can Grade 17 be welded?
Excellent GTAW/plasma/EB weldability with matching Gr17 or Gr1 filler; requires full inert trailing and back shielding, clean bright weld colour, and low-hydrogen preparation.
Can Grade 17 be formed, bent or molded?
The most formable Ti-Pd grade: cold deep-draws, bends to ~2T and spins readily; allow generous springback and warm-form (150–300 °C) heavy sections.
Grade 17 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.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| Pdcorrosion-enhancing addition; distinguishes Gr17 from Gr1 | 0.04 – 0.08 | 0.06 |
| Fe | ≤ 0.2 | 0.08 |
| OGrade 1 base — low interstitials give high ductility | ≤ 0.18 | 0.1 |
| C | ≤ 0.08 | 0.02 |

What surface finishes work on Grade 17?
Pickle in HNO₃/HF then passivate; anodizes to durable coloured oxide films; electroplating is rarely used and adhesion needs an activation strike.

Grade 17 — frequently asked
What is Grade 17 used for?
Grade 17 is typically used for deep-drawn and formed vessel components, chemical process tanks and hoppers, thin-wall condenser and heat exchanger tubing, expansion bellows and diaphragms, vessel linings and cladding sheet and spun heads and dished ends. In short: most formable Ti-Pd grade; low-Pd Grade 11 substitute; deep-draw corrosion titanium.
What is the yield strength of Grade 17?
Grade 17 has a typical yield strength of 240 MPa (34.8 ksi) and a tensile strength of 330 MPa (47.9 ksi) — weaker than 90% of titanium grades. Strength varies by condition: see the 4 listed tempers.
Is Grade 17 easy to machine?
Not especially — machinability is rated fair (40/100, better than 93% of titanium grades). Cuts like soft CP Ti — use sharp, positive-rake carbide, low speed (~30–60 m/min) with heavy flood coolant; avoid dwell and rubbing which work-harden and gall the gummy surface.
Can Grade 17 be welded?
Yes — weldability is rated excellent (88/100). Excellent GTAW/plasma/EB weldability with matching Gr17 or Gr1 filler; requires full inert trailing and back shielding, clean bright weld colour, and low-hydrogen preparation.
What surface finishes work on Grade 17?
Pickle in HNO₃/HF then passivate; anodizes to durable coloured oxide films; electroplating is rarely used and adhesion needs an activation strike.
Can Grade 17 be formed, bent or molded?
The most formable Ti-Pd grade: cold deep-draws, bends to ~2T and spins readily; allow generous springback and warm-form (150–300 °C) heavy sections.
What is the maximum service temperature of Grade 17?
Grade 17 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 Grade 17-ANN and Grade 17 CR-Hard?
ANN is the default condition — default stocked condition: maximum ductility and formability for deep-drawn heads, linings and heat-exchanger tube. CR-Hard: as-rolled thin strip/foil for anodes, gaskets and clad liners where strength and flatness matter more than drawability. Yield strength is 240 MPa in ANN versus 480 MPa in CR-Hard.
