Case hardening basics:Nitrocarburizing vs. carbonitriding

Feb 15, 2017 · Nitrogen is commonly added to low carbon, low alloy steels that otherwise wouldnt harden well as intended. The nitrogen comes in the form of ammonia, which cracks on the surface of the part to provide nitrogen that diffuses into the steel. Adding nitrogen also helps a part maintain hardness during use in high-heat settings. Classical nitriding of heat treatable steel - ScienceDirectJan 01, 2015 · In the case of steel, the mechanical properties can be linked via the tensile strength y to the Vickers hardness H by a Tabor-type law (Tabor, 1951):[10.1] H = a y with a 0.29 0.3 For nitrided layers (32CrMoV13 steel), Locquet (1998) showed that the a coefficient is close to 0.4.
