Abstrak

Pengelasan antara stainless steel dan carbon steel rentan terhadap tegangan sisa karena perbedaan koefisien muai. Properti tahan karat dan properti mekanik sambungan juga dapat terpengaruh oleh sensitisasi stainless steel yang menghasilkan presipitasi chromium carbide dan difusi karbon pada daerah heat-affected zone carbon steel. Pengaruh post-weld heat treatment pada sambungan stainless steel 316 dan AISI 1018 dengan filler metal 309L terhadap kekerasan dan struktur mikro menjadi tujuan penelitian ini. Nilai kekerasan sambungan mengalami penurunan seiring dengan peningkatan temperatur post-weld heat treatment pada rentang 400-700℃. Struktur mikro heat affected zone juga berubah dengan dominasi butiran ferrite yang mengalami grain growth.
