Many Chromium based alloys are strengthened by using heat treatment process known as age hardening. The intention of this process is to perform many uses such as to enhance the mechanical properties. By adjusting the processing conditions such as time, temperature and atmosphere. It consist of heating the metal where the constituents will form an homogeneous mass. The process will be holding at that temperature until diffusion occurs after that the quenching is done to gain the proper structure. Heat treated metals are comparatively soft and workable and unstable. After solution treatment and quenching the hardness is achieved either at room temperature or at any suitable temperature. Age hardening is one of the heat treatment process where generally low temperature and long term process. Temperature range is from 150C-250C , time varies from 10 to 50 hrs. The time and temperature is considered carefully. This is done in order to select the cycle which produces optimal distribution pattern. The mechanical behavior of B-16 material is studied by age hardening in this study. The mechanical properties are monitored by using the rock well hardness test and tensile tests. The greater the hardness of the material greater the strength of the material to withstand the plastic deformation. The value of Rockwell hardness of the stud is 258HBN and that of nut is 215 HBN. The hardness is compared with the reference value.
