How Can We Help You?



Carbon graphite wear plates & plugs

St. Marys Carbon custom manufactures a large variety of carbon and graphite grades for a wide range of wear applications. Our proprietary grades are necessary for many of the unique environments in which wear products are required. All of our products, from the blending of raw materials to the finished products, are made in-house by our specialized craftsmen.

Materials

Our wear plates & graphite plugs are made from the following materials:

We also offer various impregnations and treatments to further fit your application needs.

Custom Solutions

We have the expertise to provide you with custom solutions to fit your specific application. Have you ever encountered technical issues or questions such as the below that requires an expert’s help?

  • What do you do when you require a product with multi-functionality that cannot be met with a monolithic material?
  • How do you enhance a metallic substrate to provide multi- level lubrication properties?

This is where we provide solutions that others cannot. As a potential customer you will have at least three concerns for a supplier:

  1. Material Portfolio: We offer three primary grades for Lubrication Plugs & Wear Plates and a number of boutique Grades for niche applications.
  2. Component Manufacturing Capability: We have in-house equipment and expertise to meet your component needs. High Volume Pressed to Size, Low Volume Machined, and prototype samples – we have what it takes all under one roof.
  3. Supply Chain Support: With corporate attention to Working Capital, you need a reliable supplier that not only accepts your Purchase Orders but works with you and becomes integrated into your supply chain including in some cases contracted Finished Goods Inventory or a Kanban System for appropriate SKU’s.
