Abstract
This studyaimed to find out about the solidity analysis of spring leaf stell hardening results with coolant variations for palm blades manufacture. This research process was conducted by heating (heat treatment) to a temperature of 800cc for 30 minutes, followed by rapid cooling by free air, oil and fresh water cooling media. Hardening was done to obtain high wear resistance, and high solidity. After hardening was done, the next step wasTesting the solidity using rockwell cfor comparing which was the highest solidity value from the three coling media. In the processing of solidity analysis using rocwell c device, 9 speciments were used for samples, where each cooling media using 3 spesiments leaf spring stells. The data processing results shown that there was a 46% solidity decrease from 41 HRC to 22,1 HRC in the free air, and a solidity increase by 21% from 41 HRC to 49,8 HRC in oil cooling media. The highest solidity increase by 48% from 41 HRC to 60,7 HRC was in fresh water cooling media.
