Another alternative is direct hardening. During this process, the temperature of the workpiece after carburising is lowered to the hardening temperature for the edge layer, and rapidly quenched afterwards.<\/p>\n<p>The objective behind case hardening is to create <strong>a surface of great strength and hardness<\/strong>. However, it is intended that retains its toughness. The target hardness of the edge layer depends primarily on the amount of carbon that can be enriched. This in turn depends on the basic hardenability of the selected grade of steel.<\/p>\n<p>However, the <strong>quenching medium<\/strong> plays an important role as well. Suitable mediums include a salt melt, water, and oil, as well as helium and nitrogen. The next step in the process is tempering.<\/p>\n<p>&nbsp;<\/p>\n<h3>Tempering<\/h3>\n<p class=\" translation-block\">Tempering is the final step in the entire process. This step is required for <strong>relieving the stresses<\/strong> produced in the edge layer during carburising and hardening. This step increases ductility.
