Choose samples of material of different hardness, center punch them and get a visual size of the indent. If you can get some calibration coupons from a hardness tester, you could get the hardness quite closely. Spark testing can give you and indication of the chemistry but not the harness.

When quoting a Brinell hardness number, abbreviated to BHN or HB, the load number must be specified as well as the material the ball was made of. For example, HBS 20/3000 would mean that a hardened steel ball indenter was used. The 20 is the ball's diameter in millimeters, and the 3000 is the force in kilograms.

Brinell hardness is sometimes quoted in megapascals; the Brinell hardness number is multiplied by the acceleration due to gravity, 9.80665 m/s 2, to convert it to megapascals. The BHN can be converted into the ultimate tensile strength (UTS), although the relationship is dependent on the material, and therefore determined empirically.

Maurice Stewart, in Surface Production Operations, 2021. 6.7.6.4 Overview of Brinell hardness testing. The Brinell hardness lab test method consists of indenting the test material with a 10-mm-diameter hardened steel or carbide ball subjected to a load of 3000 kg. For softer materials, the load can be reduced to 1500 kg or 500 kg to avoid excessive indentation.
