Copyright policy )Hasil Variasi Media Quenching Terhadap Kekuatan Tarik Baja S45C
Dalam penelitian ini, baja S45C akan diuji dan dibandingkan nilai kekuatan tarik yang dimiliki sebelum dan setelah diberikan perlakuan panas <em>Quench Hardening</em>. Suhu pemanasan yang digunakan dalam proses perlakuan panas ialah 850 ℃, dengan <em>holding time </em>yaitu<em> </em>30 menit. Media <em>quenching</em> yang digunakan yaitu “Es Batu Ditambah Air”, “Larutan NaCl 3,45%”, dan “Oli SAE 10W-30”. Hasil dari pengujian tarik menunjukkan bahwa media <em>quenching</em> “Es Batu ditambah Air” dan media <em>quenching</em> “Larutan NaCl 3,45%” menghasilkan rata-rata nilai kekuatan tarik 156,27 MPa dan 228,55 MPa, sementara pada <em>raw material</em> dan media <em>quenching</em> “Oli SAE 10W-30” menghasilkan rata-rata nilai kekuatan tarik 707,03 MPa dan 1.116,30 MPa.
