Salt Bath Nitriding/Nitrocarburizing was originally created as an alternative to gas nitriding that would produce a more uniform case through surface contact between the substrate and liquid salt. The two primary benefits of the nitriding process is corrosion resistance and maintaining a barrels dimensional consistency, which improves accuracy. The surface is also very hard and protective, provided you don’t abuse the barrel with excessive heat.
It’s even cheaper to perform that chrome, to boot.
However, the nitriding process isn’t without some tradeoffs. the most important is heat and pressure resistance compared to chrome. But how important is that, really?
Let’s take a look at nitrided barrels. [Read Full Article »]
