Sales Systems Ltd. performs metallurgical testing examinations including carburization, decarburization, and case depth analysis on threaded and non-threaded fasteners. There are two types of methods: optical and micro-hardness. A Buehler micro-hardness tester which is an optical microscope with a magnification strength of 400x is our primary instrument for these analyses.
