hardness range on the relationship among Brinell hardness,
Vickers hardness, Rockwell hardness, Rockwell superficial
hardness, Knoop hardness, and Scleroscope hardness of nonaustenitic
steels including carbon, alloy, and tool steels in the
as-forged, annealed, normalized, and quenched and tempered
conditions provided that they are homogeneous.1.2 Conversion Table 2 presents data in the Rockwell B
hardness range on the relationship among Brinell hardness,
Vickers hardness, Rockwell hardness, Rockwell superficial
hardness, Knoop hardness, and Scleroscope hardness of nonaustenitic
steels including carbon, alloy, and tool steels in the
as-forged, annealed, normalized, and quenched and tempered
conditions provided that they are homogeneous.1.3 Conversion Table 3 presents data on the relationship
among Brinell hardness, Vickers hardness, Rockwell hardness,
Rockwell superficial hardness, and Knoop hardness of nickel
and high-nickel alloys (nickel content over 50 %). These
hardness conversion relationships are intended to apply particularly
to the following: nickel-aluminum-silicon specimens
finished to commercial mill standards for hardness testing,
covering the entire range of these alloys from their annealed to
their heavily cold-worked or age-hardened conditions, including
their intermediate conditions.1.4 Conversion Table 4 presents data on the relationship
among Brinell hardness, Vickers hardness, Rockwell hardness,
and Rockwell superficial hardness of cartridge brass.1.5 Conversion Table 5 presents data on the relationship
between Brinell hardness and Rockwell B hardness of austenitic
stainless steel plate in the annealed condition.
