Ball Nose Series Meets Rigors of Processing Hardened/Abrasive Steel. Boasting a new carbide blend, U.S. Union Tool's HGB/HGLB Ball nose series can cut hardened/abrasive steels in the 59-70 HRC range, and improves overall tool life. The challenge when cutting steels greater than 60 HRC and moderate steels with abrasive properties lies with the ...

The test is achieved by applying a known load to the surface of the tested material through a hardened steel ball of known diameter. The diameter of the resulting permanent impression in the tested metal is measured and the Brinell Hardness Number calculated as. BHN = 2 P / (π D (D - (D2 - d2)1/2)) (1) where. BHN = Brinell Hardness Number.
The balls on this gage set range from 2.0 mm ( 0.07874" ) to 3.4 mm ( 0.1260" ) in increments on 0.1 mm. They are used by an auto manufacturer to check the fit of auto doors. These gages are also referred to as "Gap Gages", "Gap …
The Brinell scale measures the size of the indentation left by a steel ball with a specific amount of force behind it. Typically, a 10 mm hardened steel ball is used with a force of 3,000 kgf to create the indentation, and a calibrated scope is …

The surface is hardened by pure diffusion, resulting in a surface hardness of 1100 to 1200 Vickers (comparable with > 70 Rockwell C) for 316 stainless steel. Very closely toleranced machined austenitic stainless steel parts can be hardened without any need for re-machining.
For soft materials such as copper alloys, soft steel, and aluminum alloys a 1/16" diameter steel ball is used with a 100-kilogram load and the hardness is read on the "B" scale. In testing harder materials, hard cast iron …
infinitely hard material will read 100 on the diamond penetrator scales and 130 on the ball penetrator scales. One regular Rockwell number represents a penetration of 0.002 mm (0.000080 inch). Therefore, a reading of C60 indicates penetration from minor to major load of (100 to 60 Rockwell points) x 0.002 mm = 0.080 mm or 0.0032 inch.
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 ...
