Tantalum Coating Washer

Tantalum Coating Washers are used in highly aggressive chemical bolting applications to ensure the mechanical load is distributed across a chemically inert surface. Zeron Fastners supplies washers utilizing the Tantalum (Ta) refractory metal, which is renowned for its immunity to most strong acids, including concentrated sulfuric and hydrochloric acid. These washers are essential for preventing galling and ensuring reliable joint torque in flange assemblies within chemical reactors, acid processing lines, and critical piping systems where total corrosion protection is required, especially when paired with Tantalum-lined pipes or vessels.
