Tantalum Coating Washers

Tantalum Coating Washers typically refers to washers made of a strong base material (like carbon steel or stainless steel) that are clad, electroplated, or coated with a thin layer of pure Tantalum. The purpose is to achieve Tantalum's near-total chemical corrosion immunity to strong acids and aggressive chemical media across a wide temperature range, protecting the joint interface. These washers are essential for distributing the high clamping load of the bolt/nut without compromising the corrosion resistance required for the assembly of Tantalum-lined pressure vessels, heat exchangers, and reactor components in the harshest chemical and pharmaceutical industries. Zeron Fastners supplies Tantalum-coated washers for optimal joint integrity and chemical isolation.
