Roughly half the weight of stainless, excellent seawater resistance — see the grade table below for full datasheets and equivalents within this family.
See All Grades ↓Titanium tube sheets weigh roughly 44% less than stainless or duplex equivalents at the same dimensions, while offering corrosion resistance in seawater and chlorine environments that rivals or beats duplex and super duplex. It's the specification of choice when weight matters as much as corrosion resistance — offshore platforms, ship retrofits, and any application where topside weight has a real structural or cost impact.
Grade 2 (commercially pure) covers the large majority of tube sheet applications; Grade 5 (Ti-6Al-4V) adds roughly triple the yield strength where a genuine structural strength requirement exists beyond standard pressure-boundary design.
| Grade | Designation | Best For |
|---|---|---|
| Titanium Grade 2 | UNS R50400 | Standard corrosion/weight duty — most tube sheet applications |
| Titanium Grade 5 | UNS R56400 | Higher structural strength requirement, Ti-6Al-4V |
Per kilogram yes, but since a titanium tube sheet is roughly 44% lighter for the same dimensions, the total material cost gap is often smaller than the per-kilogram number suggests.
No — the majority of applications are adequately served by Grade 2. Grade 5 is reserved for cases with an explicit structural driver beyond standard pressure design.
Yes — titanium welding requires an inert gas shield covering the weld pool and surrounding heated metal to prevent oxygen and nitrogen contamination, which embrittles the joint.
