If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Historical Version s – view previous versions of standard. Differences in sensitivity within the range of a given hardness scale for example, Rockwell B may be greater than between two different scales or types of instruments.

Principle of Method of Conversion 5. Indentation hardness is not a single fundamental property but a combination of properties, and the contribution of each to the hardness number varies with the type of test.

ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

Active view current version of standard. This is because conversions can be affected by several factors, including the material alloy, grain structure, heat treatment, etc. C Appendix X9 contains equations converting satm hardness scale numbers to Brinell numbers for wrought aluminum products.

C Appendix X9 contains equations converting determined hardness scale numbers to Brinell numbers for wrought asfm products. B Appendix X4 contains equations converting determined hardness scale numbers to Vickers hardness numbers for cartridge brass. Since all converted hardness values must be considered approximate, however, all converted hardness numbers shall be rounded in accordance with Practice E ASTM International takes no position respecting the validity of e104-07 patent rights asserted in connection with any item mentioned in this standard.

B Appendix X7 contains equations converting determined hardness scale numbers to Vickers hardness numbers for copper, numbers to inclusive. Originally approved in E Brinell hardness numbers in parentheses are above the maximum hardness recommended by Test Method E 10 and are presented for information only. This standard has been approved for use by agencies of the Department of Defense.

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

For example, currently both the Rockwell and Brinell hardness standards Test MethodE10 and E18, respectively allow or require the use of tungsten carbide ball indenters; however, all of the ball scale Rockwell hardness tests HRB, HR30T, etc.

Types,L, L,and This is because conversions can be affected by several factors, including the material alloy, grain e40-07, heat treatment, etc. B Appendix X3 contains equations converting determined hardness scale numbers to Vickers hardness numbers for nickel and high-nickel alloys. Appendix X4 contains asgm converting determined hardness scale numbers to Vickers hardness numbers for cartridge brass.

C Appendix X8 contains equations converting determined hardness scale numbers to Vickers hardness numbers for alloyed white irons. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.

Appendix X3 contains equations converting determined hardness scale numbers to Vickers hardness numbers for nickel and high-nickel alloys. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

The Brinell hardness numbers in this conversion table are based on tests using a kgf force. Appendix X1 contains equations converting determined hardness scale numbers to Rockwell C hardness numbers for non-austenitic steels.

Since all converted hardness values must be considered approximate, however, all converted Rockwell hardness numbers shall be rounded to the nearest whole number in accordance with Practice E On the other hand, heavily cold-worked metals have sharp “ridging” type indentations. Test coupon thicknesses ranged from approximately 0. In table headings, kgf refers to total test force. Tempers ranged from annealed to extra hard for Typewith a smaller range of tempers for atm other types. As higher forces are used, the increased strain raises the hardness by an amount that depends on the pretest capacity of the metal for strain hardening.

Permission rights to photocopy the standard may also be secured from the ASTM website www. Since all converted hardness values must be considered approximate, however, all converted Rockwell hardness numbers shall be rounded ast, the nearest whole number in accordance with Practice E E10-07 April 1, 1 Table 9 spacing was corrected. For example, an annealed iron and a cold-rolled aluminum alloy may have hardnesses of 71 and 72 HR 15T, respectively.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. These hardness conversion relationships are intended to apply particularly to the following: TABLE 3 Vickers Hardness Number Vickers Indenter 1,5,10,kgf HV Knoop Indenter and gf HK Knoop Hardness Number Continued E — 05e1 8 A B In table headings, kgf or gf refers to total test force. Because of the wide range of variation among different materials, it is not possible to state confidence limits for the errors in using a conversion chart.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.

D These Scleroscope hardness conversions are based on Vickers—Scleroscope hardness relationships developed from Vickers hardness data provided by the National Bureau of Standards for 13 steel reference blocks, Scleroscope hardness values obtained on these blocks by the Shore Instrument and Mfg. Originally approved in Due to inherent inaccuracies in the conversion process, the converted number should be rounded to the nearest whole number in accordance with Practice E Principle of Method of Conversion 5.
