Gas nitriding is a case hardening process. It improves wear resistance, corrosion resistance and fatigue life. Espon-an is very effective as a stop off masking compound to prevent nitriding at the required areas. Espon-kn coating decreases ammonia gas consumption in gas nitriding. It enables to use carbon fixture in place of inconel. The same form has grow up anti-scale compound for use during heat treatment, hot forging and hot rolling.
