Abstract

Baja mangan yang mengandung 1,2% C dan 12% Mn dikenal secara umum sebagai baja Hadfield. Berdasarkan tingginya kandungan unsur C dan Mn, struktur utama baja ini didominasi oleh matriks austenit yang dikelilingi fasa karbida pada batas butirnya. Struktur tersebut biasanya rapuh dan cenderung tidak layak untuk penggunaan dalam kondisi pembebanan tinggi. Pada penelitian ini dilakukan proses perlakuan panas quenching dengan memanaskan baja Hadfield hingga temperatur 1000 °C, kemudian dilanjutkan pendinginan cepat dengan menggunakan variasi media pendingin yaitu air dan air garam dengan penambahan 20 wt.% NaCl. Pemilihan variasi media pendingin ini bertujuan untuk mengetahui tingkat pembentukan fasa karbida dan pengaruhnya terhadap mikrostruktur dan sifat mekaniknya. Dari hasil pengujian didapatkan bahwa baja Hadfield dengan parameter quenching air garam 20 wt.% NaCl memiliki transformasi mikrostruktur yang signifikan sehingga berefek pada peningkatan nilai kekuatan tarik dan luluh (809,5 dan 542,4 MPa), kekerasan (238 HV), keuletan dan ketangguhannya.

Abstract

Manganese steel contains 1,2% C and 12% Mn generally recognized as Hadfield steel. Based on the high composition of C and Mn elements, the main structure of this steel is dominated by an austenite matrix that surrounded the carbide phase on the grain boundary. This structure is usually brittle which leads to improper high-loading conditions. To overcome this problem, the experimental method was carried out by heating Hadfield steel to a temperature of 1000 oC, then followed by a quenching process using cooling media variations namely water and salt bath (20 wt.% NaCl solution). These cooling media variations aim to determine the level of carbide formation which affects the microstructure and mechanical properties. From the test results, it was obtained that Hadfield steel with salt bath (20 wt.% NaCl) quenching variation has significant microstructure transformation which affects enhancement of the value of tensile and yield strength (809,5 and 542,4 MPa), hardness (238 HV), ductility and toughness.
