    • Provides excellent corrosion resistance

    3M™ Silicon Carbide Mechanical Seal Rings are effective for applications where highly aggressive fluids are present. Silicon carbide is an effective material for applications in which wear and corrosion resistance are critical concerns.

    Preferred Choice for Applications with Aggressive Fluids
    3M™ Silicon Carbide Mechanical Seal Rings offer the performance you need when looking for extended lifetime in highly aggressive fluids. Silicon carbide is a high-strength, lightweight ceramic material that is extremely hard and resistant to wear, chemicals and corrosion – even at high temperatures. These properties allow components made from 3M silicon carbide to withstand some of the most demanding conditions in a wide variety of industries including semiconductor, papermaking, chemical processing and oil and gas production.

    Customized Mechanical Seal Rings
    3M™ silicon carbide mechanical seal rings can be finish-machined to close tolerances in our fully equipped precision diamond grinding facilities. 3M silicon carbide materials can also be customized for your unique application. 3M specialists will assist you with initial design and development, and our extensive and well-equipped manufacturing facilities allow us to quickly scale-up to full production.

    Durable Under Extreme Conditions
    Our silicon carbide material offers tribological performance under high load, including pressure, sliding speed and temperature. Components manufactured from silicon carbide provide long-lasting service due to its high resistance to wear, resistance to corrosion in aggressive media and thermal shock resistance with low distortion under thermal loads.

    The Differences among Silicon Carbide Grades
    3M offers six grades of silicon carbide in this product, each exhibiting various properties. Differences are described below:

    The all-purpose grade
    3M™ Silicon Carbide Grade F 

    Good chemical resistance, low specific density, high hardness and wear resistance, outstanding thermal conductivity properties and resistance to fluctuations in temperature. 3M silicon carbide grade F combines all these specific advantages of sintered silicon carbide, particularly for bearings and seals for use in pumps.

    The corrosion-resistant grade
    3M™ Silicon Carbide Grade C 

    Resistance to corrosion is a particular problem where aggressive chemicals or hot water are being transferred, e.g. by circulating pumps. 3M silicon carbide grade C has proven highly effective in corrosive environments.

    The high-strength grades
    3M™ Silicon Carbide Grade F plus and Grade T plus 

    Two high-density materials achieve the optimum strength for silicon carbide. These non-porous, fine-grained grades are designed to provide very high mechanical strength and edge stability. 3M silicon carbide grade F plus and grade T plus are ideal materials for complex thermal and mechanical loads.

    The tribological grades
    3M™ Silicon Carbide Grade P and Grade G 

    These grades offer improved dry run and mixed friction properties that are especially valuable in sliding and friction systems.
