This makes it possible, for instance, to restrict the hardening specifically to the interior or the exterior surfaces of a component. This is accomplished through induction. For this, <strong>a copper coil is used to generate an alternating electromagnetic field.<\/strong> The electrical resistance in the component causes the development of heat, which can be used to reach the specific hardening temperature.\n\u00a0<br>\n\u00a0<br><\/p>\n<h3>Hardening procedure<\/h3>\n<p class=\" translation-block\">Unlike other hardening processes, <strong>induction hardening takes place in sequences.<\/strong> This means that each segment of the area to be hardened can be heated in turn by repositioning the inductor and quenching the segment using a sprinkler.<br>\n\u00a0<br>\nDepending on the size of the component and inductor, the workpiece can also be gradually slid through the inductor. It may also be necessary to perform a rotary motion during this process (e.g. for shafts).<br>\n\u00a0<br>\nThe stresses in the steel are subsequently relieved at low temperature or by tempering.<\/p>\n<p class=\" translation-block\"><strong>Brief heating and dwell times ensure very low oxidation.<\/strong> Formation of the desired microstructure requires that the dwell time and hardening temperature are set in the correct relationship. This relationship depends on the type of the material, and especially its carbon content. The typical temperatures lie between 800\n\u00b0C and 950 \u00b0C\n<br>\n\u00a0<br>\n<img loading=\"lazy\" class=\"alignnone size-large wp-image-1654\" src=\"https:\/\/haertha.de\/wp-content\/uploads\/2023\/01\/P1006613-1024x682.png\" alt=\"\" width=\"1024\" height=\"682\"><\/p>\n<\/p>\r\n                    <div class=\"acf-innerblocks-container\"><\/div>\r\n                    \r\n                    <style>\r\n                        .sonder-zeichen{\r\n                            display: flex;\r\n                            flex-direction: row;\r\n                            gap: 15px;\r\n                        }\r\n                        .zeichen{\r\n                            color: #C9C9C9;\r\n                            position: relative;\r\n                            line-height: 66px;\r\n                            font-size: clamp(2.75rem, 1.9766rem + 2.1484vw, 4.125rem);\r\n                        }\r\n                    <\/style>\r\n                    \r\n                <\/div>\r\n            <\/div>\r\n        <\/div>\r\n    <\/div>\r\n<\/div>\r\n\r\n\r\n\r\n\r\n\n\n\r\n<div id=\"verfahren-text-block_95367c7614002ad5e9b78446bc36bd36\" class=\"verfahren-text toc\" data-toctitle=\"Vorz\u00fcge auf einen Blick\" style=\"\">\r\n    <div class=\"row\">\r\n        <div class=\"col-12\">\r\n            <div class=\"content-wrapper\" >\r\n\r\n                            <div class=\"box\">\r\n                                            <div class=\"nummber\"> \r\n                            \r\n                        <\/div>\r\n                        \r\n                                            <h2 class=\"headline\">The advantages at a glance<\/h2>\r\n                                \r\n                <\/div>\r\n            \r\n                <div class=\"content-box texteditor\" style=\"\">                    \r\n                    <p><p>Discover some of the major advantages of inductive hardening:<\/p>\n<ul>\n<li class=\" translation-block\"><b>Locally limited hardening<\/b>  easily possible<\/li>\n<li>Quick processing time thanks to short process duration<\/li>\n<li class=\" translation-block\"><b>Slight warping<\/b> and minimum scale formation<\/li>\n<li class=\" translation-block\">Suitable for automation, and <b>reproducible<\/b><\/li>\n<\/ul>\n<\/p>\r\n                    <div class=\"acf-innerblocks-container\"><\/div>\r\n                    \r\n                    <style>\r\n                        .sonder-zeichen{\r\n                            display: flex;\r\n                            flex-direction: row;\r\n                            gap: 15px;\r\n                        }\r\n                        .zeichen{\r\n                            color: #C9C9C9;\r\n                            position: relative;\r\n                            line-height: 66px;\r\n                            font-size: clamp(2.75rem, 1.9766rem + 2.1484vw, 4.125rem);\r\n                        }\r\n                    <\/style>\r\n                    \r\n                <\/div>\r\n            <\/div>\r\n        <\/div>\r\n    <\/div>\r\n<\/div>\r\n\r\n\r\n\r\n\r\n\n\n\r\n<div id=\"verfahren-text-block_e7062ff05a1c2f7c70702153ed20d785\" class=\"verfahren-text toc\" data-toctitle=\"Anwendungsbereiche\" style=\"\">\r\n    <div class=\"row\">\r\n        <div class=\"col-12\">\r\n            <div class=\"content-wrapper\" >\r\n\r\n                            <div class=\"box\">\r\n                                            <div class=\"nummber\"> \r\n                            \r\n                        <\/div>\r\n                        \r\n                                            <h2 class=\"headline\">the process and its advantages<\/h2>\r\n                                \r\n                <\/div>\r\n            \r\n                <div class=\"content-box texteditor\" style=\"\">                    \r\n                    <p><p class=\" translation-block\">Inductive hardening is ideally suited for <strong>components with complex geometries<\/strong> and tools that are exposed to extreme wear in certain places.
