Brinell Hardness Test

The following url is for caculating Brinell Hardness.  It uses kilograms and mm instead of inches and pounds.  You put your figures into the boxes and you get a Brinnel number caculated.
I would use a dial caliper to measure.

Easy and neat

Martin,

  Neat site, and very useful if you're familiar with converting metrics over to "real" measurements.  Smiley

  For those of us that are metrically challenged here's the formula for the rest of us as published on pg. 88 of E.H. Harrisons "Cast Bullet" book.

BHN = 5 x ( diam. of indent in Lead / diam. of test sample) squared

  An example would be if the indent in a sample of pure Lead was .175" and the indent in the sample you want to know the BHN of is .103", it would figure out as.......

  .175/.103 = 1.666  1.666 x 1.666 = 2.775  2.775 x 5 = 13.875 

  Round it up to 13.9 or 14 BHN

PETE
