atau baja SS304. Baja tahan karat adalah baja panduan yang memiliki sifat tidak&#13;
muda korosi, variasi temperatur yang digunakan pada peroses perlakuan panas&#13;
atau di sebut PWHT mengunakan suhu 400°C,500°C dan 600°C dengan waktu&#13;
pemanasan 40 menit, karakteristik yang dilakukan meliputi pengujian uji tarik dan&#13;
pengujian uji impact hasil atau karakterisasi sampel tertinggi pada material SS304&#13;
pada pengujian tarik tanpa perlakuan panas atau tidak mengunakan PWHT&#13;
dengan nilai suhu 400°C = 410.5 N/mm2 suhu 500°C = 447.5 N/mm2 suhu 600°C&#13;
= 372.5 N/mm2 Normal = 395.5 N/mm2 Pada hasil pengujian impact energi&#13;
impact, normal = 157,9662 joule/mm2 tanpa suhu = 73,0296 joule/mm2 suhu&#13;
400°C = 73,7352 joule/mm2 suhu 500°C = 73,7646 joule/mm2 suhu 600°C =&#13;
73,7058 joule/mm2 dan nilai kuat impact mengalami penurunan dengan angka&#13;
normal = 1,9745775 joule/mm2 tanpa variasi suhu = 0,91287 joule/mm2 suhu&#13;
400°C = 0,92169 joule/mm2 suhu 500°C = 0,9220575 joule/mm2 suhu 600°C =&#13;
0,9213225 joule/mm2. Kondisi optimasi pada penelitian ini didapatkan pada&#13;
kondisi suhu 600°C PWHT dengan struktur dan grain hasil pemanasan dan&#13;
pendinginan menjadi tidak homogen. Hal ini disebabkan karena pada sampel&#13;
diduga pengurangan  tegangan sisa sehingga material tersebut memiliki sifat yang&#13;
lebih keras namun ketangguhannya lebih rendah. &#13;
