Opinions Wanted

Properly noted in this form, r/c 63, r/b 32, r/c 45, ect.

r = Rockwell test

c = Scale used, Lettered from a thru g dependent on type of material to be tested


Number = hardness, usually in the range of 15 to 63, which covers the most frequently used for steels 15 being in the annealed or softest condition thru 63 being Diamond hardness or near so.


Almost all hardness tests use a conical diamond for a probe.


Brinell is a differing Hardness test Similar in appearance to anyone other than those professionals working in that field.

Thanks for the thoughts, but,

Opinions are for those having a particular Knowledge of the subject matter upon which to base their opinions.

My knowledge and experience I try to limit to my experience which is purely mechanical in nature.

Each time I have stepped over that line I've been fed "Humble Pie" and it stinks.

If I were guessing, which I will not, I can only say no opinion.....
