Hardness Testing  Services

Hardness testing services are used in various industries. Hardness strengh can be identified as the ability of a material to withstand deformation as well as the permanent indentation when it comes in the contact with an indenter under load. The hardness of any material is determined by using different types of scales. These scales directly or indirectly shows the contact pressure involved in deformation of the test surface. During the testing process, the indenter is pressed into the material and therefore, hardness is also regarded as the capability of a material to withand the compressive loads. For hardness testing, different types of indenters are used like Pyramidal (Vickers And Knoop Tests), Conical (Rockwell Test) and Spherical (Brinell Test). In the Vickers, Brinell and Knoop tests, the hardness value is expressed in kgf/mm2. While in the Rockwwell tests, the depth of indentation is ascertained and converted into a hardness number. Hardness testing services are mostly used to substantiate the heat treatment effectiveness, which is applied to actual castings.

Hardness Testing  Services is perhaps the simplest and the least expensive method of mechanically characterizing a material since it does not require an elaborate specimen preparation, involves rather inexpensive testing equipment, and is relatively quick. The theoretical and empirical investigations have resulted in fairly accurate quantitative relationships between hardness and other mechanical properties of materials such as ultimate tensile strength, yield strength and strain hardening coefficient and fatigue strength and creep. These relationships help measure these properties with an accuracy sufficient for quality control during the intermediate and final stages of manufacturing. Many times hardness testing is the only nondestructive test
alternative available to qualify and release finished components for end application.
