CP 1 Ti Plate Flanges Mechanical Properties

Figures below are the ASTM B381 Grade F-1 minimums for the annealed condition.

Tensile Strength240 MPa (35 ksi) min
Yield Strength (0.2%)138–310 MPa (20–45 ksi)
Elongation24% min
Reduction Of Area30% min
Physical Properties - Titanium Grade 1 (UNS R50250)
Density4.51 g/cm³ (0.163 lb/in³) - a large blind is a two-man lift where steel needs a crane.
Melting PointApproximately 1668 °C (3034 °F) for unalloyed titanium.
Modulus Of ElasticityAround 103 GPa (15 × 10&sup6; psi), roughly half that of carbon steel.
Thermal ExpansionAbout 8.6 µm/m·°C over 0–100 °C - lower movement than austenitic piping.
Magnetic ResponseNon-magnetic, which is why it appears on survey, sensor and instrument skids.

11 · Grade Choice

Titanium Alloy Gr 1 Weld Neck Flange Grade Selection Guide

Grade 1 (R50250)

  • The softest and most formable unalloyed grade
  • Lowest oxygen and iron ceilings of the four
  • Picked for deep-drawn work, linings and water-side duty

Grade 2 (R50400)

  • Higher strength minimums than Grade 1
  • The default workhorse across process piping
  • Chosen when a thinner section has to carry the load

Grades 7 & 11 (Palladium Bearing)

  • Small palladium addition to the Grade 2 and Grade 1 bases
  • Specified against reducing acids and crevice attack
  • Costlier, so used only where the chemistry demands it

Grade 12 (R53400)

  • Lean molybdenum and nickel addition
  • Better crevice behaviour in hot chloride brines
  • A middle route between Grade 2 and the palladium grades
12 · Service Window

Commercially Pure Ti Grade 1 Reducing Flange Seawater & Chloride Service Window

Where the grade is unbeatable value, and the handful of media that call for a different answer.

Seawater & BrineAmbient seawater won't pit or stress-crack titanium, at any flow rate.
Sand & Silt LoadingErosion resistance is why water boxes use titanium.
Hot Concentrated ChloridesCrevice risk grows with brine temperature; Grade 7, 11 or 12 answers it.
Reducing AcidsHot hydrochloric and sulphuric acid attack titanium without oxidising species.
Dry Chlorine & Anhydrous MediaDry chlorine and anhydrous methanol are classic exclusions - ask us first.
Galvanic CouplingTitanium is noble against steel, so the steel corrodes; isolation kits help.
Cathodic ProtectionOver-protection can drive hydrogen into titanium; confirm potentials with us.

FAQs

Titanium Grade 1 Flanges FAQs

The questions that reach our desk before a Grade 1 order is placed.

What standard covers ASTM B381 UNS R50250 flanges?

Forgings follow ASTM B381 Grade F-1 and plate-cut bodies follow ASTM B265 Grade 1.

CP Gr 1 vs Grade 2 titanium flange?

Grade 1 is softer and more formable; Grade 2 carries higher strength minimums.

Is WNR 3.7025 in ASME B16.5 tables?

No. Dimensions follow B16.5, while the rating basis comes from your design code.

Can Ti Alloy Gr 1 bolt to carbon steel?

Only with an isolation kit. Sleeves, washers and a non-conductive gasket protect the steel side.

Do you export Ti Grade 1 orifice flanges?

Yes. KEBS PVoC, Canadian CRN and Gulf vendor dossiers are handled in house.
