Portable standard Vickers hardness block price

HW standard Vickers hardness block, hardness tester calibration block, standard test block introduction:

Vickers hardness refers to the hardness of a certain shaped hard steel indenter pressed into the surface of a specimen under standard spring test force, and the material hardness is determined by the depth of the indenter. A indentation depth of 0.01mm is defined as one unit of Vickers hardness. The unit of measurement for Vickers hardness is HW. The Vickers hardness tester is a portable, compact, lightweight, and one handed device that can quickly, conveniently, and non destructively test material hardness. It does not require sampling and does not require high operational skills, making it ideal for rapid hardness testing of materials on production sites. Vickers hardness aluminum alloy products are suitable for testing Vickers hardness. The principle of Vickers hardness is that a hard steel indenter with a certain shape is pressed into the surface of the specimen under the action of standard spring test force. The material hardness is determined by the depth of the indenter, and a pressing depth of 0.01mm is defined as one unit of Vickers hardness. The unit of Vickers hardness is expressed as HW. The characteristics of Vickers hardness instruments are poor sensitivity, narrow range, and only 20 scales in the full range. Therefore, usually one instrument can only test 1-2 types of metal materials.

HW standard Vickers hardness block, hardness tester calibration block, standard test block, difference between Vickers hardness and Vickers hardness:

Vickers hardness (Hv), also known as indentation hardness, is more accurate than Mohs hardness (Hm), which is relative hardness. Vickers hardness and Mohs hardness can be converted to each other through calculation. Vickers hardness refers to the hardness of a certain shaped hard steel indenter pressed into the surface of a specimen under standard spring test force, and the material hardness is determined by the depth of the indenter. A indentation depth of 0.01mm is defined as one unit of Vickers hardness.

Vickers hardness refers to the use of a diamond pyramid indenter with a relative angle of 136 degrees between its faces, which is pressed into the surface of the test sample under a specified load F. After holding for a certain period of time, the load is removed, the diagonal length d of the indentation is measured, and the indentation surface area is calculated. Finally, the average pressure on the indentation surface area is calculated, which is the Vickers hardness value of the metal, represented by the symbol HV. In actual measurement, it is not necessary to perform calculations, but to directly check the table based on the measured d value to obtain the measured hardness value.

Using a load of 49.03~980.7N, press a square cone diamond with a relative angle of 136 ° into the surface of the press material, maintain it for a specified time, measure the diagonal length of the indentation, and then calculate the hardness according to the formula. It is suitable for hardness measurement of larger workpieces and deeper surface layers. Vickers hardness still has low load Vickers hardness, which is suitable for measuring the hardness of thinner workpieces, tool surfaces, or coatings; Micro Vickers hardness.
