Frequently Asked Questions

Titanium Grade 2 Circles & Discs are circular components made from commercially pure titanium Grade 2, manufactured from plate, sheet, or forged stock for fabrication and machining.
Yes. They offer excellent resistance to seawater, chlorides, oxidizing environments, and many corrosive chemicals.

ASTM B265 is the specification for titanium and titanium alloy strip, sheet, and plate, including Grade 2 material used to produce cut circles and discs.

UNS R50400 is the Unified Numbering System designation for commercially pure Titanium Grade 2.

Grade 2 is commercially pure titanium with excellent corrosion resistance and formability, while Grade 5 is Ti-6Al-4V and provides significantly higher strength.

Yes. They can be supplied in customized diameters, thicknesses, shapes, machining conditions, and surface finishes according to project requirements.
Primarily as blanks for flange forging, ring-type-joint gaskets, and round components in chemical-processing and marine equipment.
The terms are largely interchangeable; ‘circle’ is more common for plate-cut flat blanks, while ‘disc’ is often used for forged or thicker blanks intended for further machining.
Yes, most suppliers cut circles to specified diameter and thickness by laser, plasma or waterjet depending on required edge finish and tolerance.
