※ Solution annealing
Heat treatment applied to austenitic steels. It consists of heating to
a high temperature followed by cooling sufficiently rapidly to preserve
a homogeneous austenitic structure on return to ambient temperature.

※ Brinell Hardness
Value of applied test force (N) {kgf} divided by surface area of
permanent indentation (㎟)
Hardness symbol HBS shall be used when indenter of steel ball is used
and HBW when indenter of sintered hard alloy steel is used.

※ Hardness
Degree to which metal will resist cutting, abrasion,
penetration, bending and stretching.
The indicated hardness of metals will differ somewhat with
the specific apparatus and technique of measuring.
For details concerning the various types of apparatus used
in measuring hardness, see Brinell Hardness and Rockwell
Hardness. Tensile Strength also is a indication of hardness.
