Mohs Hardness Scale: Testing the Resistance to Being Scratched

Mohs hardness test: When conducting the test, place the unknown specimen on a table top and firmly hold it in place with one hand. Then place a point of the reference specimen against a flat, unmarked surface of the unknown specimen. Press the reference specimen firmly against the unknown, and deliberately drag it across the flat surface while pressing firmly.

Metal Hardness: The Definite Guide (with Hardness Chart

HBS indicates that the indenter is a hardened steel ball, which is used to determine materials with a Brinell hardness value below 450, such as mild steel, gray cast iron and non-ferrous metals. HBW indicates that the indenter is a hard alloy, which is used to measure materials with a Brinell hardness value below 650.

The Mohs Scale of Hardness for Metals: Why It Is Important

For example, platinum, which has a hardness of 4-4.5, can be scratched by all materials that have a higher Mohs grade (such as topaz, which is graded 8), and it can in turn scratch any material that is graded lower (e.g., gold, which has a hardness of 2.5-3).

Hardness UMD

In testing harder materials, hard cast iron and many steel alloys, a 120 degrees diamond cone is used with up to a 150 kilogram load and the hardness is read on the "C" scale. The Rockwell test uses two loads, one applied directly after the other. The first load, known as the "minor", load of 10 kilograms is applied to the specimen to help seat

Brinell hardness (HB), rockwell hardness (HRC), Vicker

The Vickers hardness has the same basic principle as with all common measures of hardness, is to observe the questioned material's ability to resist plastic deformation from a standard source. According to our experience, as for the iron and steel castings, the Brinell hardness is more common in China.

What is RUST on Moh's hardness scale? : geology

Short version trying to get rust (iron oxide) off some iron weightlifiting plates. Steel is a 4-4.5 and iron is a 4. So theoretically, if I used a steel wire brush I would degrade the plates right? But if rust (because it is iron oxide, not just iron) has a lesser hardness could I just use an Iron brush or something?
