St. Marys Carbon manufactures Rotors & Vanes from superior carbon graphite grades for a variety of applications. Our rotors & vanes are made from specialized, proprietary materials that are required for many of the unique environments in which rotors & vanes are used. All of our rotors & vanes, from the blending of raw materials to the finished product, are made in-house by our specialized craftsmen.
Our rotors & vanes are made from the following materials:
We also offer various impregnations and treatments to further fit your application needs.
If you require a customized solution, we can manufacture our carbon graphite rotors and vanes to your specific requirements. We develop our own proprietary grades and manufacture each product in-house, so we will work closely with you to create a carbon graphite product that is right for you.

Greatly reduces failure rates and allows for use in sanitary environments due to its self-lubricating properties.
Maintains high strength and runs effectively without failure at high temperatures.
Resists wear and reduces friction as it is chemically inert, oxidation-resistant and self-lubricating.
