Mortec Manufacturing Co forges Titanium Grade 7 flanges from traceable billets. Each blank carries its heat number before reaching modern CNC lines. Grade 7 titanium with small palladium addition resists harsh reducing acids. These flanges easily survive hot hydrochloric and sulphuric acid chemical service. Precision machining strictly follows ASME B16.5 and B16.47 standards. We offer RF and RTJ facing with smooth finish options. Custom bore drilling matches your exact isometric drawings for seamless fit. Working direct lets us skip intermediate trading layers for lower prices. All flange types are available from Class 150 to 2500. Every single dispatch carries PMI reports and EN mill certs.

08 · Joint Choice
Commercially Pure Ti Grade 7 Lap Joint Flange Weld Neck Vs Slip On In Reducing Acid Service
Both patterns are ASTM B381 UNS R52400. The joint geometry is what decides service life.
| Joint Behaviour | Weld Neck Flange | Slip On Flange |
|---|---|---|
| Weld type | Full penetration butt weld | Two fillet welds |
| Gap left at joint | None | Narrow annular gap |
| Crevice risk in acid | Very low | Present unless seal welded |
| Bore continuity | Matched to pipe schedule | Step at the pipe end |
| Radiography on weld | Possible | Not practical |
| Cyclic and vibration duty | Preferred | Limited |
| Class range advised | 150 through 2500 | 150 through 600 |
| Fit up on site | Cut length critical | Forgiving |
| Relative cost | Higher | Lower |
Why palladium widens the Slip On window on this grade.
Film Holds In The Gap
Palladium keeps the passive layer alive
Grade 2 Pits In The Gap
Plain titanium loses its film fast
Slip On Becomes Viable
Mild acid duty suits the cheaper pattern
Weld Neck Stays Safer
Hot acid lines still need a butt weld
Send the media and the class and we confirm the pattern in writing.
09 · Grade Choice
Ti Grade 7 Vs Grade 2 Titanium Flange
The question every buyer asks before approving the price gap. Palladium is the only real difference.
Titanium Grade 2
PalladiumNone
Tensile Minimum345 MPa
Oxidising AcidsFully passive and reliable
Reducing AcidsCorrodes once the film breaks
Crevice RiskRises in warm chloride
Choose WhenSeawater and neutral chloride duty
Titanium Grade 7
Palladium0.12 to 0.25 percent
Tensile Minimum345 MPa and identical
Oxidising AcidsFully passive and reliable
Reducing AcidsStays passive far longer
Crevice RiskMuch lower in warm chloride
Choose WhenHot acid and gasket crevice duty
Strength is the same in both grades. You are buying corrosion life and not extra load capacity.

FAQs
Titanium Grade 7 Flanges FAQs
Five questions land on nearly every Grade 7 enquiry. All answered plainly below.
What makes Titanium Grade 7 Flanges different from Grade 2?
- Grade 7 adds 0.12 to 0.25 percent palladium to the same unalloyed titanium base.
- Tensile still starts at 345 MPa and a Titanium Alloy Gr 7 Blind Flange weighs the same as Grade 2 at 4.51 g/cm3.
- The palladium buys corrosion life in reducing acids, not extra strength.
Which standard covers Grade 7 Titanium Slip On Flange forgings?
- ASTM B381 Grade F-7 covers the forging and ASME SB381 is the matching code section.
- An ASTM B381 UNS R52400 Threaded Flange follows the same forging spec, dimensioned to ASME B16.5.
- Bar stock runs to ASTM B348 Grade 7 and plate to ASTM B265 Grade 7.
What sizes and classes do you hold in Ti-0.15Pd Blind Flange?
- Half inch to 24 inch NB held ready in Class 150 through Class 2500.
- CP Gr 7 Titanium Socket Weld Flanges stop at NPS 3, the limit ASME B16.5 sets for that pattern.
- Ti Metal Gr 7 Orifice Flanges begin at Class 300 under ASME B16.36, and a Ti Grade 7 Reducing Flange is made to order.
Can Titanium Gr 7 Weld Neck Flange handle hydrochloric acid?
- Yes in dilute and warm hydrochloric service, where palladium keeps the passive film stable.
- CP 7 Ti Long Neck Flanges give the same result on vessel nozzles, with no crevice left at the butt weld.
- Only the stub end wets on a Commercially Pure Ti Grade 7 Lap Joint Flange, so send concentration and temperature for written confirmation.
What documents ship with a WNR 3.7235 Plate Flanges order?
- EN 10204 3.1 mill test certificate as standard, Type 3.2 third party on request.
- Invoice, packing list, COO and a PMI report confirming the palladium band.
- The same file follows every pattern we ship, down to Titanium Alloy Gr 7 Puddle Flanges.
