    en.wikipedia.org/wiki/Steel_grades

    For alloys in general (including steel), unified numbering system (UNS) of ASTM International and the Society of Automotive Engineers (SAE). American steel grades : AISI/SAE steel grades standard; British Standards; International Organization for Standardization ISO/TS 4949:2016; European standards – EN 10027

  4. Rockwell hardness test - Wikipedia

    en.wikipedia.org/wiki/Rockwell_hardness_test

    A Rockwell hardness tester. The Rockwell hardness test is a hardness test 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]

  5. 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 ...

  6. Barcol hardness test - Wikipedia

    en.wikipedia.org/wiki/Barcol_hardness_test

    The governing standard for the Barcol hardness test is ASTM D 2583. [4] Barcol hardness is measured on a scale from 0 to 100 with the typical range being between 50B and 90B. A measurement of 60B is roughly equivalent to a Shore hardness of 80D or a Rockwell hardness M100.

  7. SAE steel grades - Wikipedia

    en.wikipedia.org/wiki/SAE_steel_grades

    The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International.. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.

  8. Alloy 20 - Wikipedia

    en.wikipedia.org/wiki/Alloy_20

    Alloy 20 is an austenitic stainless steel containing less than 50% iron developed for applications involving sulfuric acid.Its corrosion resistance also finds other uses in the chemical, petrochemical, power generation, and plastics industries.

  9. Template:Bar chart - Wikipedia

    en.wikipedia.org/wiki/Template:Bar_chart

    Each bar can also have a comment, such as "comment7=xx" to show "(xx)" after the number in bar 7. For a 2-column bar chart, the 2nd column items have prefix "col2_" such as scale maximum, col2_data_max=110, and col2_data3=67 with col2_comment3=zz. See below: "Example with two data columns". Each bar chart can be formatted typically within 1/5 ...
