metal property that can influence the scope and quality - this is the hardness. In order to determine the special equipment. To determine you can contact the experts. that metal hardness check was better, you need to determine the method that is ideal. There are several major scales that can be used. Consider the most popular varieties, a method of investigating the best use.
The main scale and methods
The first option - it is a way to Brinell. Quite common method, which is used even proven company. For this purpose, a metal sample by using special equipment pressed into a small steel ball. After that mark appears on it. This kind of hole, which allows to determine the level of hardness of the metal. You can purchase a hardness, which determines the level of hardness is the Brinell method. Be sure to choose a certified device.
Next - Rockwell method. The scale of hardness is considered to be one of the samyhz popular. In order to obtain a certain measure, on metal arrive certain load. First - this is the depth of penetration of the indenter into the material. After that, the indenter is immersed into the material since the load. After that, the difference between the obtained values. Please note that the Internet can be found indicators of Rockwell's most popular types of metal. What is the indenter? This is a special ball, which is made on the basis of steel. It is also often used special cone, made on the basis of aluminum. If the first option is determined by the peculiarities of the wells, the method Rockwell - depth, which is obtained after the study. Note that this method can be carried out only if the metal does not have any damage. Otherwise it may be damaged or performance may differ materially from actual.
It is also possible to apply the method Vickers. He is quite popular, while not held by a ball and a special pyramid. It must necessarily have a vertex with an angle of 136 degrees. Note that this element is also pressed into the material. Definition goes on features, performance diagonal, which was formed on the metal. Vickers method also allows to determine the hardness of the metal in depth.
