Models for Predicting Tempering Hardness (Austenitic Temperature 900?C)

Dr. Mohammed Ahmed Mohammed Mansour | Khalid Bushra Elhaj Fadul Mohammed ^[2]

Abstract: Hardness of steel depends on type of heat treatment adopted on its composition. The main heat treatment processes are annealing, normalizing and tempering. the process parameters play a vital role in achieving the required hardness. In this paper different quenching media have been used to accomplish this work with help of Microsoft excel package to find sound model gives relation between hardness and its corresponding tempering temperature. This achieved by doing several experiments at austenitic temperature of 900oc and quenching in oil, water, and brine. Then tempered to different temperatures (200oc up to 600oc) using medium carbon steel (locomotive axle steel)
