Grade 12 Titanium (Ti-0.3Mo-0.8Ni)
UNS R53400 — Ti-0.3Mo-0.8Ni, the cp-plus-stabilisers grade. Published corrosion data puts Gr12 ahead of Gr2 in hot chloride/brine service; that is exactly why evaporators, brine heaters and hot seawater exchangers specify it.
| Property | Value |
|---|---|
| Tensile (min) | 483 MPa |
| Yield (min) | 345 MPa |
| Mo | 0.25 – 0.5 % |
| Ni | 0.6 – 0.9 % |
Grade 12 vs Grade 2
Ambient chloride duty: Gr2 remains the economic choice. Hot brine, elevated-temperature seawater condensers, crevice-prone joints: Gr12 is the common-practice upgrade — final call belongs to your service data.

FAQ
Is Gr12 the desalination grade?
It is the hot-side upgrade frequently specified for brine heaters and evaporator tubing; cold seawater lines usually stay Gr2.
Availability vs Gr2?
Schedule product — lead times longer than Gr2; plan early for project quantities.
