Abstract
AISI 430 Ferritic Stainless Steel is well known for its good corrosion resistance applicable for high resistance to pitting and stresses. But it lacks in its wear resistance and hardness in order to improve the mechanical properties of AISI 430 Ferritic Stainless-Steel materials Nitriding Heat Treatment is chosen in this project. The samples are taken in the form of cylindrical shapes with diameter 10mm and length 40mm respectively. The specimen is subjected 4 numbers being the highest treated to saturated limit. One specimen is kept as untreated for comparison purpose. Wear test will be carried out under constant speed and with variable load by pin on disk wear testing apparatus. Finally, all the specimens are subjected to various metallographic tests like SEM (Scanning Electron Microscope) and EDAX (X-ray Despresive Analysis) or XRD (X-ray Diffraction) and the results are compared.
