Titanium circles and discs are flat, round blanks of titanium sheet or plate or forged stock that have a specific diameter and thickness. They are typically used in the manufacture of flange blanks, tubesheets, sealing parts and other precision parts that demand not only corrosion resistance but also good mechanical properties. Grade 2 (minimum tensile strength of 345 MPa) is generally used for chemical or marine fabrication, and Grade 5 is chosen for applications that require greater strength. Sachin Steel Centre manufactures Titanium Circles & Discs in various grades and sizes, Titanium Grade 2 Sheets & Plates and other products associated with fabrication applications.
