What is 316Ti Annealed?
316Ti Annealed is 316Ti in the Annealed temper — generic softened stock designation used by distributors; mechanically equivalent to the solution-annealed condition. 316Ti Annealed has a yield strength of 255 MPa (37 ksi) and a tensile strength of 575 MPa (83.4 ksi) — weaker than 87% of stainless steel grades. Elongation at break is 45% and the elastic modulus is 200 GPa (29 Msi). 316Ti Annealed has a density of 8 g/cm³ (0.289 lb/in³), heavier than 92% of stainless steel grades. It melts at 1,375°C (2,507 °F). Solution Annealed is the default condition FabDigit quotes; Annealed is available on request or by drawing note.

Working with 316Ti Annealed
Is 316Ti easy to machine?
Gummy and work-hardening with abrasive TiC particles — use rigid setups, positive-rake coated carbide, 25–60 m/min, heavy constant feed and flood coolant; avoid dwelling.
Can 316Ti be welded?
Excellent by GTAW/GMAW/SMAW without pre- or post-weld heat treatment; use 318 (ER318 / 1.4576, Nb-stabilized) or 316L filler, low heat input, back-purge tube welds.
Can 316Ti be formed, bent or molded?
Cold forms and deep draws well but with higher springback and force than carbon steel; anneal 1020–1120 °C + rapid cool after severe forming, hot work 1150–900 °C.
What surface finishes work on 316Ti?
Pickle and passivate (ASTM A967) or electropolish after welding; mirror polishing is limited by titanium inclusion streaks, so choose 316L for decorative bright finishes.

316Ti Annealed — frequently asked
What is 316Ti Annealed used for?
316Ti Annealed is typically used for chemical pipework, reactor vessels, heat exchanger shells and tubes, expansion joints and bellows, flue-gas and exhaust ducting and pressure vessel flanges and fittings. In short: titanium-stabilized 316 stainless.
What is the yield strength of 316Ti Annealed?
316Ti Annealed has a typical yield strength of 255 MPa (37 ksi) and a tensile strength of 575 MPa (83.4 ksi) — weaker than 87% of stainless steel grades. Strength varies by condition: see the 6 listed tempers.
Is 316Ti Annealed easy to machine?
Not especially — machinability is rated fair (38/100, better than 63% of stainless steel grades). Gummy and work-hardening with abrasive TiC particles — use rigid setups, positive-rake coated carbide, 25–60 m/min, heavy constant feed and flood coolant; avoid dwelling.
Can 316Ti Annealed be welded?
Yes — weldability is rated excellent (85/100). Excellent by GTAW/GMAW/SMAW without pre- or post-weld heat treatment; use 318 (ER318 / 1.4576, Nb-stabilized) or 316L filler, low heat input, back-purge tube welds.
