Sheets are tested for their suitability for deep drawing or stamping, by measuring penetration depth in a specimen to which press. is applied in the penetration direction, and a tension in a direction perpendicular to the press. The device has two movable punches applying adjustable press. to th...
The tester should be recalibrated/verified every time you change the indenter or objective lensSurface preparation requirements for hardness testing Before hardness testing of metallic materials or other materials, you must prepare the surface. The required surface condition depends on the type of test...
The Knoop Hardness Test is applied for testing soft material and thin coating, since the penetration depth is very small (about 1/30 of the impression length). The loading force in the Knoop method are usually in the range of 10 gf to 1000gf (micro-hardness range). The Knoop number ...

The test involves hot rolling fine sized shale pieces in the inhibitor fluid for 16 h at 150 °F, recovering shale pieces on a 50-mesh sieve and placing them into a bulk hardness tester. Torque wrench is used to compress the samples providing the maximum torque required to compress them. ...
HR-150AS Rockwell Hardness Tester Manual Digital Display Manual Rockwell Hardness Tester HR 50AS ● HRA is widely used to measure hardness of carbide alloy, quenched hardening steel after carbonized, hardened thin steel strip and plate, etc.For materials HRC > 67, it is more likely to damage...
If a thin or brittle material needs to be tested, it is better to use a superficial Rockwell scale. It creates a shallower indentation and uses a lower load to prevent destructive materials like ceramics and sheet metal. How to evaluate hardness using Rockwell hardness tester? The Rockwell ...
In order to obtain precise results, sample preparations are necessary. A sample that is adequately small to fit in the tester is required. Furthermore, the preparation should have a smooth surface to achieve a regular indentation shape and accurate measurement. This also ensures that the subject ...
