Determine the hardness of very hard steel. To use, slide a test bar into the tester, place the tester on your surface, and hit with a hammer; a steel ball will make an impression. Measure the impression with the 20X microscope and use the computing disc to determine hardness.
Rockwell T - 1/16" diameter steel ball indenter Thin materials, lightly carburized steel surfaces; SGS MSi's engineers review all material and required specifications to ensure your hardness testing is being performed to the correct parameters. The sample preparation is the most critical part of the hardness test.
The softer the material, the larger should be the diameter of the ball and / or the smaller should be the total test load. For instance, the materials that can be tested with the HRB scale (ball 1/16" – total test load 980.7N) are harder than the materials tested with the HRL scale (ball 1/4 "- total test load 588.4N).

An alternative method is the Brinell hardness test, which uses a hardened steel (or tungsten carbide) ball indenter with a diameter D of, usually, 10 mm. This is applied under a load P of 500–3000 kg applied for 10–30 s. The diameter of the circular indentation d is measured in millimetres. The hardness number, (HB) is calculated using the following equation:
The Rockwell Superficial hardness test method consists of indenting the test material with a diamond cone (N scale) or hardened steel ball indenter. The indenter is forced into the test material under a preliminary minor load F0 (Fig. 1A) usually 3 kgf. When equilibrium has been reached, an indicating device that follows the movements of the ...

The Brinell test uses a hardened steel or carbide ball with a diameter of 10 mm as an indenter with a load of 3000 kgf to be applied on the material. Due to the high load applied, this test is often used to test hardened steels, although for softer materials the load can be reduced to avoid excessive indentation.

Brinell Hardness Test (BHN) The Brinell Hardness Test consists of indenting the test material with a 10mm diameter hardened steel or carbide ball subjected to a load of 3000 kg. For softer materials, there are alternate scales using a 1500 kg or 500 kg load to avoid excessive indentation.
To determine the hardness of soft materials by the Rockwell method, a hardened steel ball with a diameter of 1.588 mm (1/16″) is used instead of the diamond cone. Hardness is determined by pressing the indenter into the test specimen under the effect of two successively applied loads, i.e. preliminary load P 0 and main load P 1 which is added ...

What I use is a steel ball (can be any size from 1/4 to 3/4")and a known ingot of pure lead (hardness of 5 BHN) about the size of the test sample. You just press the ball between what you want to test and the known pure lead sample and run this formula.
Hardness is a characteristic of a material, not a fundamental physical property. It is defined as the resistance to indentation, and it is determined by measuring the permanent depth of the indentation...
Rockwell B-Scale Hardness 1/16 inch diamond ball, 100 kgf load : Symbol: HRB : The Rockwell Hardness Test presses a steel or diamond hemisphere-conical penetrator against a test specimen and measures the resulting indentation depth as a gage of the specimen hardness. The harder the material, the higher the HR reading.
In Rockwell testing, hardness is determined by measuring the comparative depth of two carefully controlled indentations, one superimposed over the other. First a Minor Load (one of a lesser force) is applied to a steel ball or sphero—conical diamond penetrator.
