Abstract

Jenis penelitian adalah penelitian eksperimental yang bertujuan untuk mengetahui pengaruh proses quenching terhadap kekerasan pada baja assab dengan menggunakan media pendingin yang berbeda. Media yang digunakan berupa larutan air, oli, dan larutan garam. Penelitian dilakukan pada bulan mei 2019 di Laboratorium Pendidikan Teknik Mesin FKIP Universitas Sriwijaya dan laboratorium metalurgi Teknik Mesin Universitas Sriwijaya. Hasil penelitian didapatkan nilai baja setelah dilakukan proses quenching diperoleh bahwa baja yang memiliki nilai kekerasan tertinggi yaitu baja yang menggunakan media larutan garam sebesar 243,946 kg/mm2 dan diikuti menggunakan media air sebesar 220,742 kg/mm2 dan yang paling kecil menggunakan media pendingin oli yaitu sebesar 209,019 kg/mm2. Presentasi kenaikan kekerasan dari baja assab 8407_2M yaitu oli sebesar 5,10%, media air sebesar 11% dan larutan garam 22,75 %.
