Electrochemical machining (ECM) is an advanced technology that enables the efficient and precise machining of difficult metal materials without affecting their mechanical properties or causing thermal stress. In this research, ECM was used for machining 316 stainless steel; it is recognized for its high corrosion resistance, tolerance to harsh chemical environments, and biological stability, making it ideal for use in surgical instruments, sutures, and implants. The development of eco-friendly electrolytes has the potential to impact the safety and performance of electrochemical devices. the development of eco-friendly electrolytes remains a challenging task for well operability. In this research, the possibility of using eco-friendly acidic sodium nitrate solution electrolyte in the ECM of SS316 was investigated. The experimental results manifested that using ECM with SS316 achieves effective results in terms of material removal rate and surface roughness. The results showed that the voltage was the sturdiest affecting parameter, followed by acidified sodium nitrate concentration on MRR as well as for the surface roughness (SR). As it was found that higher MRR (0.0823) was achieved with voltage of (30 V), electrolyte concentration of (100), and gap of (0.2 mm). besides the lowest SR (0.1881 µm) was achieved with voltage of (30 V), electrolyte concentration of (125), and gap of (0.3 mm).
