The chemical composition of X38CrMoV5-3 steel is given in the table below. b) This steel is austenitized at 1050 ° C and hardened by giving water in oil (completely martensite structure has been formed and has a hardness of 57 HRC) and tempered at 510 ° C to reduce its hardness (54 HRC) and gain toughness. In addition, it is desired to harden the surface by nitration. In order to achieve the desired surface hardness, liquid nitration should be done at 600 ° C, gas nitration at 510 ° C and plasma nitration at 450 ° C. Which nitration method do you prefer?
