First, it has a higher resistance to softening during menstruation and higher fatigue and impact resistance.\u00a0 This method is especially applied to steels with low surface hardenability. For example, this method is applied to the valve bed; The parts are first carburized around 900-955\u00b0C, after the desired depth is achieved, the carbonitriding process is started and then cooled in oil. The surface hardness of the resulting part is higher than the hardness that will be achieved in carburizing; In addition, the carbonitriding layer formed on the surface\u00a0 increases the compressive stresses on the surface, increasing the contact fatigue strength.<\/p>\n<p><strong>Applications<\/strong><\/p>\n<p>Typical applications: gear threads, eccentric, axle, bearing, hydraulic piston rods, fasteners, tools and dies.<\/p>\n<blockquote class=\"wp-embedded-content\" data-secret=\"uFIXBpLCFo\">\n<p><a href=\"https:\/\/www.teknovak.com\/en\/austempering-and-hardening-furnace\/\">Austempering and Hardening Furnace<\/a><\/p>\n<\/blockquote>\n<p><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; clip: rect(1px, 1px, 1px, 1px);\" title=\"&#8220;Austempering and Hardening Furnace&#8221; &#8212; TeknoVak\" src=\"https:\/\/www.teknovak.com\/en\/austempering-and-hardening-furnace\/embed\/#?secret=XfyY7wSjdi#?secret=uFIXBpLCFo\" data-secret=\"uFIXBpLCFo\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>\n","protected":false},"excerpt":{"rendered":"Carbonitriding is a metallurgical surface modification technique used to increase the surface hardness of a metal and thus reduce wear.
