Abstract

Stud bold on the part used for iron pipe connection applications requires special heat treatment use of oil and gas pipeline connection, SCM440 is commonly applied as a spare part of the machine and the stud bolt due to its toughness. The purpose of this research is to know the influence of the quenching media variations in the viscosity of the oil on the strength and microstructure of the steel material SCM 440. In this study, the steel SCM440 was treated with hardening at a temperature of 850°C with a retention time of 1 hour, and was quenched using variations in SAE 40w, SAE 60w, and SAE 80w oil viscosity, and tempered at 600°C for 1 hour. The strength of SCM440 steel increases with the higher viscosity of the oil, in a large sequence the strength of the SAE 40w, SAE60w and SAE80w oil viscosities obtained strength values 267,07 HV, 286,52 HV, 329,84 HV, and followed by the analysis of micro structures that tend to change from pearlite to cementite and the abundance of martensite elements with increasing values of oil viskosity. Key Words : Stud bold, SCM440, Viscosity of the oil, Micro structures
