文档介绍：Designation: E 140 – 05e1Standard Hardness Conversion Tables for MetalsRelationship Among Brinell Hardness, Vickers Hardness,Rockwell Hardness, Super?cial Hardness, Knoop Hardness,and Scleroscope Hardness1This standard is issued under the ?xed designation E 140; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or standard has been approved for use by agencies of the Department of —The layout of Table 2 was editorially corrected in August . Scope* ConversionTable 1presents data in the Rockwell Chardness range on the relationship among Brinell hardness,Vickers hardness, Rockwell hardness, Rockwell super?cialhardness, Knoop hardness, and Scleroscope hardness of non-austenitic steels including carbon, alloy, and tool steels in theas-forged, annealed, normalized, and quenched and temperedconditions provided that they are ConversionTable 2presents data in the Rockwell Bhardness range on the relationship among Brinell hardness,Vickers hardness, Rockwell hardness, Rockwell super?cialhardness, Knoop hardness, and Scleroscope hardness of non-austenitic steels including carbon, alloy, and tool steels in theas-forged, annealed, normalized, and quenched and temperedconditions provided that they are ConversionTable 3presents data on the relationshipamong Brinell hardness, Vickers hardness, Rockwell hardness,Rockwell super?cial hardness, and Knoop hardness of nickeland high-nickel alloys (nickel content over 50 %). Thesehardness conversion relationships are intended to apply par-ticularly to the following: nickel-aluminum-silicon specimens?nished mercial mill standards for hardness testing,covering the entire range of these alloys from their annealed totheir heavily cold-worked
