The Brinell hardness numbers in this conversion table are based on tests using a kgf force. The conversion values, whether from the tables or calculated from the equations, are only approximate and may be inaccurate for specific application.

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 Each type of hardness test is subject to certain errors, but if precautions are carefully observed, the reliability of hardness readings made on instruments of the indentation type will be found comparable. Methods for Hardness Determinations 3.

Soft annealed metals have characteristic” sinking” type indentation contours when indenters of the ball type are used. An annealed 20 metal of high capacity for strain hardening will harden much more in the test than will a cold-worked metal.

These hardness conversion relationships are intended to apply particularly to the following: B In table headings, kgf or gf refers to total test force.

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

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. 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.

Originally approved in Such values are shown for comparative purposes only, where comparisons may be desired and the recommended machine and scale are not available.

E Scale kgf, in. C Appendix X9 contains equations converting determined hardness scale numbers to Brinell numbers for wrought aluminum products.

The modulus asm elasticity has been shown to inuence conversions at high hardness levels; and at low hardness levels conversions between hardness scales measuring depth and those measuring diameter are likewise inuenced by differences in the modulus of elasticity. Most Rockwell hardness numbers are presented to the nearest 0.

Due to inherent inaccuracies in the conversion process, the converted number should be rounded to the nearest whole number in accordance with Practice E B Appendix X5 contains an equation converting determined Brinell hardness numbers aetm Rockwell B hardness numbers for austenitic steel plate in the annealed e14-007. Originally approved in Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

It is necessary to base hardness conversions on comparative tests of similar materials that also have very similar mechanical properties.

B Appendix X2 contains equations converting determined hardness numbers to Rockwell B hardness numbers for non-austenitic steels. The conversion values, whether from the tables or calculated from the equations, are only approximate and may be inaccurate for specific application.
