Disc Springs for Chemical Environments
➤ Nickel Plated H-13 Disc Springs & Nickel Plated 17-7 Disc Springs
The advanced Nickel Plated Technology gives AIGI NIF Disc Springs a high wear and corrosion resistant surface.
The special coating protects the spring metal surfaces from scratching and provides protection from acidic and alkaline corrosion during working application. The highly protected surface can even withstand prolonged exposure to halogens.
This tremendous corrosion resistance dramatically extends the disc spring life and greatly enhances its preload ability.
