Webcore hardness of property class 10.9 fasteners to HRC 36 (the permitted range in the standard is HRC 33 to HRC 39) to further reduce the risk of brittle fracture. • On 10.9 fasteners use zinc flake type coatings (Geomet, Delta Protekt, etc) or mechanical zinc plating instead of electroplating. The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). There are different scales, denoted by a single letter, that use … Meer weergeven The differential depth hardness measurement was conceived in 1908 by Viennese professor Paul Ludwik in his book Die Kegelprobe (crudely, "the cone test").
