What is nitriding treatment? A technical book explaining the characteristics of nitriding and gas nitriding treatments, including the relationship between processing time, processing temperature, and hardness.
Nitriding treatment is a chemical surface hardening method of surface hardening heat treatment, which combines with various metal elements to form hard nitrides that harden the surface. The purpose of nitriding treatment is to improve wear resistance, fatigue resistance, corrosion resistance, and heat resistance. The most popular special steel that is easy to nitridize is SACM645 (commonly known as nitriding steel), which contains Al, Cr, and Mo. Other suitable materials for nitriding include chromium-molybdenum steel, nickel-chromium-molybdenum steel, and stainless steel.
