Brinell Hardness Abbreviation Designation.
HBW? Why do I see
Brinell Hardness records
with these different abbreviations?
BHN has seen years of use as the designated abbreviation for Brinell
Hardness Number, usually used in documents specifying or certifying hardness tests,
the abbreviation followed by the number value, e.g. BHN 217.
ASTM has changed the standard for Brinell tests, now requiring the use
of a carbide indention ball for all tests using a 3000 kg load (steel
balls no longer allowed).
ASTM changed the abbreviation written with the hardness value number to
HBW to indicate positively that the tester utilized a carbide ball. ASTM
has made small adjustments to the hardness number charts to account for
the change in balls.
