The rockwell hardness tester for sale is a test that determines the hardness of a material. It is based on the principle that when an indenter (usually a diamond or a steel ball) is forced into a material, it will leave behind an impression. The size of the impression is then measured and the material’s hardness is determined.
A wide range of different hardness testing techniques exist, each with its own advantages and disadvantages. The most common methods of testing metals include the Brinell, Rockwell and Vickers tests. Grainger offers an extensive selection of both analog and digital hardness testers designed to help you quickly and accurately measure the hardness of many types of materials, including steel. Our products offer a choice of scales, indenter sizes and depth measurement capabilities to best suit your application, as well as features that make them easy to use and maintain.
Our hardness testers can be used to determine the hardness of many different metal alloys, including carbon steel, cast iron, nonferrous metals and engineering plastics. They are also available in configurations that allow you to test for both regular and superficial Rockwell hardness. We have models that can even convert your results to other popular scales, such as HB, HV, HRC and HK.
To get the most accurate and consistent results possible, it is important to choose the right indenter for your application. For metals that require high test loads, such as wrought iron or steel, we recommend using a diamond indenter. For lower test loads, a standard steel indenter will work.
Our digital hardness testers are highly portable and feature a simple touchscreen display for quick and convenient operation. They offer a choice of scales and indenter sizes for maximum flexibility, and they automatically load and unload the main test force for more precise measurements. These hardness testers are ideal for use in heat treat facilities, tool rooms, workshops and inspection labs.
If you need a more nondestructive method of hardness testing, consider an ultrasonic hardness tester for sale. This type of testing uses sound waves to evaluate the quality of solid materials, such as metals and concrete, without damaging them. This technology is particularly useful for determining the hardness of small precision parts or thin wires. It can also be used to detect internal defects in large components that would be difficult to inspect using other methods.
