Abstract
Disclosed herein are corrosion inhibitors suitable for heavy-duty industrial lubricants and industrial lubricating compositions including such corrosion inhibitors combined with phosphonate diesters to provide good copper corrosion and roller bearing protection. The corrosion inhibitor has a high content of dialkyl dithiothiadiazole compounds configured to maintain high levels of the phosphonate diester in the lubricant.
