Abstract

B Baja SMO 254 selama ini digunakan sebagai plat landasan blok pencetak pada mesin tamping di PT. International Chemical Industry. Harga material mentah baja SMO 254 yang dinilai cukup tinggi menjadi alasan untuk dicari alternatif material pengganti dalam rangka menghemat biaya pengadaan suku cadang. Material pengganti yang ditentukan dalam penelitian ini adalah baja St 37 yang ditambah proses alumunizing. Karakterisasi terhadap material baja St 37 aluminizing menjawab pertanyaan apakah baja St 37 aluminizing mampu memiliki sifat kekerasan dan anti korosi yang relatif sama dengan baja SMO 254. Metode penelitian diawali dengan pemotongan sampel, proses hot dip aluminizing, uji keras, uji korosi, uji metalografi dan data yang dihasilkan dianalisa lalu diambil kesimpulan. Hasil pe elitian sebagai berikut. Hasil uji kekerasan mentmjukkan bahwa kekerasan ja SMO 254 diatas baja St 37 dengan selisih sebesar 1,63%, sedangkan p a aluminizing baja St 37 menjadi 10,95%. Hasil uji korosi menunjukk. .iwa laj rosi baja St 37 jauh diatas baja SMO 254 dengan selisi ar 2 : ,35 9(0, seriangkap baja St 37 pasca aluminizing menjadi 257,58 asil metalografi inedunjukkan bahwa terjadipembesaran ukuran butir fer n ter - tuknya laMn1117e7firtikaan intermetalikFeAl pada baja St 37 pasca ciffiratiltaik ke, !asilialleakni baja St 37 dan baja St 37 teraluminizing belum dapat digunakan untuk menggantikan material baja SMO 254.

S SMO 254 steel has been used as a base plate for molding blocks on the tamping machine at PT. International Chemical Industry. The price of raw material for SMO 254 steel, which is considered quite high, is the reason to look for alternative material substitutes in order to save the cost of procuring spare parts. The replacement material determined in this research is St 37 steel which is added with aluminizing process. Characterization of St 37 aluminizing steel material answers the question of whether St 37 aluminizing steel is able to have hardness and anti-corrosion properties that are relatively the same as SMO 254 steel. The research method begins with sample cutting, hot dip aluminizing process, hard test, corrosion test, metallographic test and The resulting data is analyzed and then conclusions are drawn. The results of the research are as follows. The results of the hardness test show that the hardness of SMO 254 is above St 37 steel with a difference of 1.63%, while the aluminizing pa of St 37 steel is 10.95%. Corrosion test results show. The yield rate of St 37 steel is far above that of SMO 254 steel with a difference of ar 2: .35 9(0, a series of St 37 steel after aluminizing to 257.58 metallographic acyl indicates that there isenlargement of the grain size of fer n formed laMn1117e7 intermetallic frictionFeAl on post-ciffiratiltaik St 37 steel, naturally St 37 steel and teraluminized St 37 steel cannot be used to replace SMO 254 steel material.
