Table  2  shows  the  average  results  of  mechanical  properties. For both aging conditions, H950 and H1000, the  tensile strength, yield strength, elongation (EL) and hardness  values are above the typical specifications of AMS 5963 8 ,  which are 47 HR
Figure 1 and Table 3 show the morphology of titanium nitride  (TiN) particles and the EDS results of particle and matrix of  steel on H950 aging condition confirming that the particle  is enriched with titanium.
