Korosi merupakan kerusakan material logam yang disebabkan reaksi antara logam dengan lingkungannya yang menghasilkan oksida logam dan sulfida logam atau hasil reaksi lainnya yang lebih dikenal sebagai pengkaratan. Stainless steel merupakan jenis baja yang tahan terhadap korosi karena memiliki unsur paduan minimal 18% chrom (Cr) dan 8% nikel (Ni).Penelitian ini menggunakan tahanan polarisasi dengan menggunakan software 342 Sotcorr Corrosion Meansurement software yang dilengkapi dengan Potensiostat/Galvanostat 273, lalu dilakukan uji foto optik dengan pembesaran 50 kali, untuk mengetahui permukaan spesimen dengan perbesaran struktur pada stainless steel 304 tersebut. Objek penelitian menggunakan stainless steel 304 dengan ukuran spesimen 10 mm sebanyak 3 kali pengujian. Stainless steel AISI 304 mempunyai nilai masa jenis 7,94 gr/cm² dan berat ekuivalen 25,12 gr.Hasil dari metode tahanan polarisasi pada sample pertama didapatkan potensial korosi -336,54 mV dan laju korosi 0,0201 mpy, pada sample kedua potensial korosi -359,25 mV dan laju korosi 0,0266 mpy, selanjutnya pada sample terakhir didapatkan potensial korosi -353 mV dan laju korosi 0,0221 mpyDownloads
