Abstract: Serious health issues can develop in people from eating contaminated food, especially if the food production pipelines are not adequately maintained. Preventing biofilm formation on the interior surfaces of pipelines in these industries is crucial for ensuring food safety. SAP is an advanced, non-traditional technique used for achieving nano scale finishing on very hard non-ferrous materials like stainless steel and ceramics. For precise finishes, costly abrasives such as Alumina, Silicon carbide, and Diamond powder are utilised. Although SAP is not a novel concept, it requires initial setup restoration, high operational costs, and have few thermal issues with abrasive materials. This study explores the parameters of nano scale finishing using sintered abrasives like Green Silicon Carbide and Electrolytic Iron powder with permanent rare earth magnets arranged in a zig-zag pattern on 18-8 Stainless Steel. The findings indicate that the gap between the 18-8 stainless steel work-piece and SAP magnetic tool has the greatest impact on PISF, followed by circumferential speed, achieving highest of 94% PISF with a 1.17% material extraction rate.
