Products for Above 3000°F (1650°C)

Many of RSI's materials have melting points well above 3000°F. Factors such as shrinkage and differential heating can lead to failures above this temperature. In certain applications our materials can be used above 3000°F (eg: intermittent high temperatures, exothermic welding). If you have an application above 3000°F, please call to discuss your application with our knowledgeable staff. They will be able to validate one of our materials, if applicable.
