I need to get a set of dies for my 45 acp. I have RCBS carbide dies for 380, 9MM, 38 Special & 357. I have no complaints - these are good dies. Any body have both the nitride & carbide dies? What do you think?

Ion nitriding
Applications for ion nitriding range from improving the wear resistance of small tool-steel die sections to hardening large iron-alloy sheet-metal drawing punches weighing 10 tons or more.
Unlike the older gas-nitriding process, a glow discharge or ion process takes place when direct current (DC) voltage is applied between the furnace (as the anode) and the workpiece (as the cathode). The furnace atmosphere consists of a nitrogen gas level that is much less than atmospheric pressure.
Ion-nitriding furnaces are available that are large enough to process the largest dies commonly used in automotive, appliance, and aerospace industries. The process is often preferred to chromium plating for large die applications
