  5. Rockwell scale - Wikipedia

    en.wikipedia.org/wiki/Rockwell_scale

    A Rockwell hardness tester. 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). [1]

  6. List of blade materials - Wikipedia

    en.wikipedia.org/wiki/List_of_blade_materials

    A6, a grade of tool steel which air-hardens at a relatively low temperature (approximately the same temperature as oil-hardening grades) and is dimensionally stable. Therefore, it is commonly used for dies, forming tools, and gauges that do not require extreme wear resistance but do need high stability.

  7. Brinell scale - Wikipedia

    en.wikipedia.org/wiki/Brinell_scale

    The Brinell hardness is designated by the most commonly used test standards (ASTM E10-14 [2] and ISO 6506–1:2005) as HBW (H from hardness, B from brinell and W from the material of the indenter, tungsten (wolfram) carbide). In former standards HB or HBS were used to refer to measurements made with steel indenters.

  8. Unified numbering system - Wikipedia

    en.wikipedia.org/wiki/Unified_numbering_system

    A UNS number only defines a specific chemical composition, it does not provided full material specification. Requirements such as material properties (yield strength, ultimate strength, hardness, etc.), heat treatment, form (rolled, cast, forged, flanges, tubes, bars, etc.), purpose (high temperature, boilers and pressure vessels, etc.) and testing methods are all specified in the material or ...
