Abstract

Baja austenitic manganese steel merupakan baja paduan dengan kandungan mangan sebesar 11%-14%. Baja ini sering digunakan di industri pertambangan maupun Asphalt Mixing Plant (AMP). Seringkali kegagalan terjadi karena tidak sesuai dengan standar ASTM A-128. Sifat mekanik tersebut dapat dipengaruhi oleh kandungan yang terdapat pada baja tersebut. Ada berbagai unsur yang mempengaruhi baja tersebut, salah satunya yaitu mangan itu sendiri, dimana mangan tersebut merupakan unsur penstabil austenit, oleh karena itu diharapkan mangan yang cukup dapat membuat fasa austenit lebih stabil di temperatur ruang. Unsur lain yang tak kalah penting yaitu krom, molybdenum, dan vanadium. Pada review jurnal ini, didapatkan hasil yang optimal untuk unsur mangan sebanyak 10-15%, kemudian vanadium dengan unsur sebanyak 0-2%, dan molybdenum sebanyak 0-2%. Kata Kunci : Austenitic Manganese Steel, krom, Mangan, Vanadium, Molybdenum ========================================== Austenitic manganese steel is a steel that contains 11%-14% manganese. This steel is broadly used for mining industries and asphalt mixing plant industries. Mostly, failures happen because the mechanical properties don’t correspond with the standards itself, which is ASTM A-128, where the optimal hardness for this steel is around 209-215 HB. Mechanical properties are affected by the element of the manganese steel itself, for example is manganese. Manganese is an elemnt that stabilize austenite phase on room temperature, which is expected to be able to get austenite phase on room temperature. Other important element that affects the mechanical properties are Chrome, Vanadium, and Molybdenum. In this paper review, the optimal manganese steel is at 10-15% range, vanadium is optimal at 0-2% range, and molybdenum is optimal at 0-2% range.
