Abstract: Hastelloy C276 a versatile corrosion resistant alloy, is investigated at 298 K. The tribological properties such as frictional force, In the micro-hardness test at 40 N load, the hardness is increased by 25 % as compared to 10, 20, 30 N loading conditions. The experimental results indicated reduction in coefficient of friction values and thus an increase in the frictional force with the increase in normal load. The images of worn out surfaces confirm that the delamination and adhesion causes the material removal from the surface in dry sliding. Further, the analysis of the hardness characteristics of worn out surfaces shows surface hardening during sliding wear process under 40 N loads. The study on the corrosion wear behavior in the sulphuric acid showed a significantly lower value of corrosion rate (0.0016579 mm/y in H2SO4 solution) in comparison to other alloys frequently used in industries.
