**Hastelloy Blind Flanges** are produced using advanced nickel-molybdenum-chromium alloys such as Hastelloy C22, C276, and C2000. These alloys have a concentration of as much as 60% nickel, together with substantial concentrations of chromium and molybdenum, imparting excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in oxidizing and reducing environments. The mechanical properties involve tensile strengths as high as 790 MPa and yield strengths of about 355 MPa. Blind flanges seal the end of a piping system or vessel, provide pressure testing, maintenance, and future expansion with full corrosion resistance.
