Assessment of Wear Behavior on Treated AISI 630 Stainless Steel by Salt Bath Nitriding Process under Dry Sliding Conditions

Grade 630 martensitic precipitation hardening stainless steel has a combination of high hardness and strength after suitable heat treatment. The great advantage this grade is that they are usually supplied in the condition treated with solution then aged to achieve sufficient strength. Chosen for research work, AISI samples were subjected salt bath nitriding process. Three chosen shape tapered cylindrical shapes diameter 10 mm length 40 mm. specimens 60 Minutes, 120 180 Minutes named as SBN1, SBN2, SBN3 respectively. One untreated specimen kept aside comparison purpose specimens. After treatment process wear test conducted by pin on disc machine. Then carried out using Rockwell test. microscopic images taken Scanning electron microscope. results compared best resistant material required application.
