A pre-nitriding option for low-pressure vacuum carburizing, PreNitLPC broadens the applications for LPC vacuum carburizing by utilizing higher carburizing temperatures. PreNitLPC is a modern, fast and economical addition to our standard low-pressure carburizing system that enhances the process by significantly reducing cycle times. Through dosing of the nitrogen carrier during controlled heat-up ramp, the furnace can run at higher temperatures (1000°C/1800°F and above) while maintaining a fine grain structure within the case. The strength properties are similar to work that has been conventionally carburized at lower temperatures. This technology saves process costs by reducing the carburizing cycle time and reducing the consumption of process gases.
