Heef® & Heef® KR

HEEF® 25 is a proprietary high-speed chromium plating process that deposits functional (hard) chromium up to four times faster than conventional chromium processes and up to three times faster than other high-speed baths.

This speed comes from an increase in current efficiency from the bath chemistry and a significantly higher limiting current density before burning occurs. Unlike other high-speed chromium plating processes, such as those based on mixed catalyst systems, the HEEF® 25 process does not cause cathodic low current density etching of parts. Deposits from the HEEF® 25 process have micro-hardness values in the 1,000-1,150 KHN0.1 range and are micro-cracked at greater than 1,000 cracks per inch. The deposit is bright, shiny and smooth.

Micro-cracked Hard Chrome is...

It is considered the ultimate Chrome for wear protection with a hardness of between 900 – 1100 Vickers (70 Rockwell C).

Usually deposits start at .0006” to .001” on printing and general engineering rollers and .005 - .010” rad deposits for reclamation or heavy wear items.

In environments that require a combination of corrosion and wear protection, a layer of Bronze or Nickel on Steel with a final coating of Hard Chrome is usually the industry standard in particular for Hydraulic Cylinders etc.
