PreNitLPC – fast and economical vacuum carburizing<\/h2>\n

\"wykr\"<\/p>\n

A\u00a0pre-nitriding option for low pressure vacuum carburizing, PreNitLPC broadens the applications for LPC Vacuum Carburizing by\u00a0utilizing higher carburizing temperatures. PreNitLPC is a\u00a0modern, fast and economical addition to\u00a0our standard low pressure carburizing system that enhances the process by\u00a0significantly reducing cycle times.<\/p>\n

Through dosing of the nitrogen carrier during controlled heat up ramp,\u00a0 the furnace can run at\u00a0higher temperatures (1000\u00b0C\/1800\u00b0F and above), while maintaining a\u00a0fine grain structure within the case. The strength properties are similar to\u00a0work that has been conventionally carburized at\u00a0lower temperatures.<\/p>\n

This technology saves process costs by reducing the carburizing cycle time and reducing the consumption of process gases (C2H2, C2H4, H2, NH3) as measured in liters and not, as in the case of conventional technologies, in cubic meters per hour. PreNitLPC is a unique process offering total value in both cost of operation & process efficiency.<\/p>\n
