This causes the <strong>carbon and nitrogen to diffuse into the steel surface<\/strong>. The component is afterwards quenched in water, oil, or a salt melt. The process concludes by tempering the component at 160 \u00b0C to 300 \u00b0C in order to reduce brittleness.<\/p>\n<p class=\" translation-block\">Compared to carburising, <strong>carbonitriding requires lower temperatures<\/strong>, between 820 \u00b0C and 900 \u00b0C, and is also generally shorter. These are ideal prerequisites for minimum warping. What is more, the nitrogen lowers the cooling rate that is critical for the formation of martensite, resulting in improved hardenability.<\/p>\n<p class=\" translation-block\">The hardness penetration depth depends on the general hardenability of the steel grade, the component geometry, the carbonitrided layer, the hardening temperature, and the cooling rate. The <strong>maximum hardness penetration<\/strong> that can be achieved with carbonitriding is 1.0 mm.<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-1588\" src=\"https:\/\/haertha.de\/wp-content\/uploads\/2023\/04\/carbonitrieren-verfahrensablauf_ENG.png\" alt=\"\" width=\"1024\" height=\"1024\" srcset=\"https:\/\/haertha.de\/wp-content\/uploads\/2023\/04\/carbonitrieren-verfahrensablauf_ENG.png 2000w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/04\/carbonitrieren-verfahrensablauf_ENG-300x300.png 300w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/04\/carbonitrieren-verfahrensablauf_ENG-1024x1024.png 1024w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/04\/carbonitrieren-verfahrensablauf_ENG-150x150.png 150w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/04\/carbonitrieren-verfahrensablauf_ENG-768x768.png 768w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/04\/carbonitrieren-verfahrensablauf_ENG-1536x1536.png 1536w, https:\/\/haertha.de\/wp-content\/uploads\/2023\/04\/carbonitrieren-verfahrensablauf_ENG-12x12.png 12w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><i><span style=\"font-weight: 400;\">Steps of the carbonitriding process<\/span><\/i><\/p>\n<h3><\/h3>\n<p>&nbsp;<\/p>\n<h3>Categorisation of carbonitriding heat treatment<\/h3>\n<p class=\" translation-block\">Despite the name of the process, <strong>carbonitriding is not a nitriding process<\/strong>.
