numbers shall be followed by the symbol HV for Vickers hardness, or HK for Knoop hardness, and be supplemented by a value representing the test force in kgf. Examples: 450 HV 10 = Vickers hardness number of 450 obtained with a test force of 10 kgf, 700 HV 0.1 = Vickers hardness number of 700 obtained with a test force of 100 gf (0.1 kgf), 500 .hardness conversion chart700 HV 10 / 20 ⇒ Hardness value as per Vickers . 700 HV 10 / 20 ⇒ Abbreviation for Vickers hardness . 700 HV 10 / 20 ⇒ Test force specification: Test force [N] = 9.807 * test force specification . 700 HV 10 / 20 ⇒ Application time of the test force (omitted if it is between 1-15 s)
Basically, it can be said that the Vickers method is increasingly becoming the most common method in practice due to its wide range of possible applications, even if sample preparation is necessary and the evaluation .The Vickers hardness test is represented by (HV). The test is the method to measure the hardness of thin sections or small parts of materials. The test proceeds by throwing the light load on the material test surface to produce penetration to create an indentation. The intender used in this method is diamond.That’s why these standards formulate tables for conversion process, with test load and hardness ranges. Here are the hardness tables and conversion charts for you. + 86 755 61301520 HV, HB, HRC Hardness Comparison Chart. Hardness testing is the simplest and most straightforward method among mechanical property tests. In order to replace certain mechanical property tests with hardness tests, a relatively accurate conversion relationship between hardness and strength is needed in production.. .
