Effect of quenching medium on hardness of three grades of steel - AISI 1040, 1050 and 4340
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 1
Abstract
Medium carbon steel contains higher percentage of carbon and thus gives better response to the heat treatment processes. Also the hardness of medium carbon steel can be improved by quenching through different quenching mediums. The present investigation emphasizes on improving the hardness property of three different types of steel AISI 1040, 1050 and 4340 having varying carbon content. Hardening was carried out for the selected steels through different quenching mediums like water, oil, brine and air for different soaking time of 30, 60 and 90 minutes at 8500C. The hardness values under all the processes have been measured to show the comparison in this investigation.
