What Are ASTM B265 Grade 2 Titanium Plates?
ASTM B265 is the standard for titanium and titanium-alloy strip, sheet and plate. Grade 2 is the most widely used commercially pure (CP) titanium grade. It gives the best balance of strength, ductility, weldability and corrosion resistance among CP grades. It weighs about 57% as much as steel, and its 345 MPa minimum tensile strength is similar to many carbon steels.
Grade 2 Titanium Plate – Quick Facts
- Grade: ASTM B265 Grade 2, UNS R50400, DIN 3.7035
- Standards: ASTM B265 / ASME SB265; ASME Section VIII and B31.3 approved
- Forms: plate, sheet, strip and coil

Properties of ASTM B265 Grade 2 Titanium Plates
- Strength: 345 MPa (50 ksi) minimum tensile and 275 MPa (40 ksi) minimum yield strength.
- Light weight: density 4.51 g/cm³ – about 57% of steel.
- Corrosion resistance: practically immune to seawater, brine, wet chlorine, hypochlorite and nitric acid; no chloride stress-corrosion cracking.
- Formability: good cold formability – easier to form than Grade 3 or alloy grades.
- Weldability: readily welded by TIG / plasma with full inert-gas shielding of the weld and back.
Where Grade 2 Titanium Works – and When to Use Another Grade
- Ideal: seawater and brine, chlor-alkali and bleach plants, nitric acid, many organic acids and oxidising chlorides.
- Use Grade 7 or 12 instead: hot reducing acids (HCl, H₂SO₄) and hot brines where crevice corrosion is a risk.
- Avoid: hydrofluoric acid and fluorides, dry chlorine gas and red fuming nitric acid.
- Temperature: CP Grade 2 is normally used up to about 300 – 350 °C in pressure equipment.

Heat Treatment & Fabrication
- Annealing: Grade 2 plate is supplied annealed; stress-relieving after heavy forming is typically done at about 480 – 595 °C.
- Welding: TIG / plasma with trailing and back-purge argon shielding; a bright silver or light straw colour indicates a sound weld.
- Cleanliness: keep free of iron contamination – use dedicated titanium tools and storage.
