Komposisi carbon material ST 37 yang   rendah ditreatment dengan variasi temperature Hardening process 790?C, 830?C dan 870?C dengan tujuan untuk melihat responsivitas material terhadap terbentuknya martensite. Pengujian kekerasan Vickers  dan struktur Mikro dilakukan untuk mendapatkan nilai kekerasan dan struktur mikro yang terjadi setelah proses hardening. Nilai kekerasan  rata rata temperature hardening 790?C sebesar 147,8 HV, sedangkan temperature 830?C sebesar 141,6 HV terakhir dengan temperature 870?C didapat 140,5 HV. Variasi Temperatur hardening ternyata relative  tidak mengubah nilai kekerasan , bahkan masih lebih rendah dibandingkan rata rata kekerasan Raw Material  sebesar  198,9 HV. Struktur mikro yang didapat dengan variasi temperature hardening baik 790?C, 830?C maupun 870?C ternyata mengindikasikan struktur ferrit dan pearlite, sama dengan struktur mikro raw material ST 37 .

abstract
	The low carbon composition of the ST 37 material was treated with variations in the Hardening process temperature of 790?C, 830?C and 870?C in order to see the responsiveness of the material to the formation of martensite. Vickers hardness and microstructure testing were carried out to obtain the hardness and microstructure values that occurred after the hardening process. The average hardness value of 790?C temperature hardening is 147.8 HV, while the last 830?C temperature is 141.6 HV with a temperature of 870?C obtained 140.5 HV. The variation of hardening temperature did not change the hardness value, even lower than the average raw material hardness of 198.9 HV. The microstructure obtained by varying the hardening temperature, both 790?C, 830?C and 870?C, turned out to indicate the structure of ferrite and pearlite, the same as the microstructure of raw material ST 37 .
