What is Ti Grade 32?
Ti Grade 32 (UNS R55111), known as Ti-5-1-1-1, is a near-alpha titanium alloy catalogued with the lean-alloy and commercially pure titanium grades. It combines moderate strength with good weldability and toughness for pressure-vessel and offshore riser work, and is available annealed, beta annealed, solution treated and aged, or stress relieved. Annealed values are 700 MPa yield, 790 MPa tensile, 15 % elongation and about 280 HB (29 HRC), with service to 400 °C. Machinability is the main constraint (rating 22) along with moderate formability (55); Ti-6Al-4V is the nearest higher-strength alternative. Ti Grade 32 has a density of 4.51 g/cm³ (0.163 lb/in³), heavier than 57% of titanium grades. It melts at 1,600°C (2,912 °F). Ti Grade 32 has a yield strength of 700 MPa (102 ksi) and a tensile strength of 790 MPa (115 ksi) — stronger than 52% of titanium grades. Elongation at break is 15% and the elastic modulus is 110 GPa (16 Msi).
What is Ti Grade 32 used for?

Working with Ti Grade 32
Is Ti Grade 32 easy to machine?
Machine like Ti-6Al-4V: rigid setup, sharp uncoated-carbide or coated tools, 30–60 m/min, heavy flood coolant, positive rake and constant feed to avoid work-hardened glazing and fire risk from fine chips.
Can Ti Grade 32 be welded?
Excellent GTAW/GMAW/EBW response with matching or Grade 32/Ti-5111 filler; requires full inert shielding of weld, backside and trailing HAZ below ~400 °C and scrupulously clean, oxide-free joints.
Can Ti Grade 32 be formed, bent or molded?
Cold forms with generous bend radii (≈4–5 t) and springback allowance; hot forming or SPF-type work at 700–900 °C is preferred for tight radii and thick plate.

Ti Grade 32 — frequently asked
What is Ti Grade 32 used for?
Ti Grade 32 is typically used for offshore riser components, pressure vessels and subsea equipment. In short: near-alpha, weldable and tough; 400 °C service capability; riser-grade titanium plate.
What is the yield strength of Ti Grade 32?
Ti Grade 32 has a typical yield strength of 700 MPa (102 ksi) and a tensile strength of 790 MPa (115 ksi) — stronger than 52% of titanium grades. Strength varies by condition: see the 3 listed tempers.
Is Ti Grade 32 easy to machine?
Not especially — machinability is rated poor (22/100, worse than 55% of titanium grades). Machine like Ti-6Al-4V: rigid setup, sharp uncoated-carbide or coated tools, 30–60 m/min, heavy flood coolant, positive rake and constant feed to avoid work-hardened glazing and fire risk from fine chips.
Can Ti Grade 32 be welded?
Yes — weldability is rated excellent (85/100). Excellent GTAW/GMAW/EBW response with matching or Grade 32/Ti-5111 filler; requires full inert shielding of weld, backside and trailing HAZ below ~400 °C and scrupulously clean, oxide-free joints.

Cold forms with generous bend radii (≈4–5 t) and springback allowance; hot forming or SPF-type work at 700–900 °C is preferred for tight radii and thick plate.
What is the maximum service temperature of Ti Grade 32?
Ti Grade 32 is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Ti Grade 32-ANN and Ti Grade 32-STA?
ANN is the default condition — standard stocked condition for plate, bar and tube — balanced strength, ductility and weldability. STA: used when a modest strength uplift is needed in bar/forgings; costs ductility and some toughness. Yield strength is 700 MPa in ANN versus 820 MPa in STA.
