High quality and behavior of steel is playing an essential role in metal and manufacturing industries. Hardox steel has exceptional properties includes high wear resistant and hardness. The wear behavior of hardox 400 steel was evaluated through pin on disc tribometer using different input constraints such as load, sliding velocity and disc speed. The wear worn surface was investigated through atomic force microscopy. The wear rate of the hardox steel was calculated with different load conditions. The wear factors and wear rate were optimized by taguchi method. Variance analysis was provided the contribution of each factor on mass loss.

In metal forming process, laser machining is plays a foremost role. It is utilized to machine very hard profile with exceptional quality characteristics. Domex 700 steel has high strength and wear resistant. The formability, durability and weldability of the domex steel are better than other grade of steels. Laser beam machining is suitable to machine domex steel with different input constrains such as power of laser, laser speed and standoff distance (SoD). The responses such as rate of metal removal (RMR) and surface roughness (SR) were recorded based on the variation of input factors. The effect and quality characteristics were optimized through taguchi approach. The variance analysis was provided the contribution of each factor with their effect on the response.
