Titanium Grade 1
UNS R50250 EN / W.Nr. 3.7025
The softest, most formable titanium — deepest drawing and best corrosion resistance of the CP grades. Plate heat-exchanger plates, anodes, explosive clad and lining work.
Titanium — Corrosion-Proof Plate, Tube, Bar, Forgings and Fasteners
Titanium Grades 1, 2, 5, 7, 9 and 12 as plate, sheet, condenser tube, pipe, bar, forgings and fasteners — the standard answer to seawater and chloride-bearing chemical corrosion at half the weight of steel.
Titanium — Material Overview
Titanium forms a thin, self-healing oxide film that makes it effectively immune to seawater, wet chlorine, chlorides and most oxidising media — with a density of 4.5 g/cm³, roughly half that of steel and nickel alloys. Commercially pure Grade 2 is the workhorse of chemical and power-plant tubing; Grade 5 (Ti-6Al-4V) supplies aerospace-level strength; Grade 7 (Pd-bearing) handles reducing acids and crevice corrosion; Grade 12 is the economical upgrade of Grade 2.
We supply titanium to ASTM B265 / B338 / B861 / B348 with ASME code-cased equivalents for pressure-vessel work. All material ships with heat-traceable chemistry and mechanical test certificates.

Titanium Grade 2
UNS R50400 EN / W.Nr. 3.7035
The workhorse CP titanium — the optimum of strength, formability and weldability. Condenser and heat-exchanger tubing, process vessel linings, pipework and fasteners in chemical and marine duty.
Titanium Grade 5 (Ti-6Al-4V)
UNS R56400 EN / W.Nr. 3.7165
The most specified titanium alloy — aerospace-grade strength with good fatigue performance. Airframe and engine parts, high-strength fasteners, forgings, medical implants and performance engineering.
Titanium Grade 7
UNS R52400 EN / W.Nr. 3.7235
Grade 2 with a small palladium addition — the top titanium for reducing acids (hot MgCl₂, dilute HCl/H₂SO₄) and crevice corrosion. Where Grade 2 pits, Grade 7 survives.
Titanium Grade 12
UNS R53400 EN / W.Nr. 3.7105
Ti-0.3Mo-0.8Ni — an economical alternative to Grade 7 with better high-temperature strength. Shell-and-tube exchangers and vessels in chemical plant where crevice corrosion is a risk.
Titanium Grade 9 (Ti-3Al-2.5V)
UNS R56320
Ti-3Al-2.5V — an intermediate-strength alloy between Grade 2 and Grade 5 with excellent cold formability. The standard alloy for aerospace hydraulic tubing and bicycle frame tube, and a weight-saving choice for high-pressure fluid lines.

Frequently Asked Questions
Grade 2 or Grade 5 — which do I need?
Grade 2 is chosen for corrosion resistance and formability at moderate strength — tubing, vessels, linings. Grade 5 (Ti-6Al-4V) is chosen where strength-to-weight matters — fasteners, shafts, aerospace parts. If the service is corrosive but not highly stressed, Grade 2 is the economical default.
Why is titanium so corrosion resistant?
It forms a stable, self-healing oxide film that regrows instantly if scratched. That film is immune to seawater, wet chlorine and oxidising chlorides at temperatures where stainless steels pit and crevice-corrode.
Where does titanium need Grade 7 or 12?
In reducing acids (hot concentrated MgCl₂, dilute HCl/H₂SO₄) and tight crevices, plain CP titanium can attack. The palladium in Grade 7 (or Mo/Ni in Grade 12) extends resistance to those conditions.
Can titanium be welded?
Yes — CP grades weld readily by TIG with careful inert-gas shielding; the weld must stay protected from air until below ~400 °C or it embrittles. Grade 5 is weldable with more attention to filler and technique. We can advise per joint and standard.
Is titanium cost-effective compared to stainless steel?
Per kilogram it is more expensive, but per installed lifetime in chloride service it often wins: condenser tubing in titanium routinely outlives multiple sets of stainless or CuNi tubes. Our calculators give the weight — and the weight saving is another 40–45% versus steel.
