Grainger carries hardness testers for sale that provide reliable testing for materials, such as metals and steel. These versatile devices are used for a variety of applications in metallurgical laboratories, quality control departments and failure analysis centers. A hardness tester uses a force to create an indentation on the surface of a sample, which is then measured to determine the material’s strength. The most popular models use the Rockwell or Brinell methods to make an impression on a piece of sample material. Others are based on the Knoop microhardness test method, which requires a diamond indenter and light test loads.
Choose a hardness tester for your specific needs from a wide selection of portable, handheld or bench-mounted units. Our inventory includes high-quality analog and digital models that can convert to a number of different hardness scales. rockwell hardness tester for sale are a great option for testing soft-bearing metals, such as cast iron or steel. They also can be used to evaluate a variety of other metals and alloys, including stainless steel, aluminum and titanium.
Other hardness testers can be used to measure the harder, softer, or medium-hardness of samples. For example, the Brinell hardness testing method uses a steel ball to mark the surface of a sample. This type of testing can be useful on rough samples that are difficult to handle using other methods. The Brinell method provides more precise and accurate results than the Rockwell or Vickers methods.
Another type of metal hardness tester is the Knoop microhardness testing method, which uses a narrow diamond shaped indenter and very light load levels. This type of testing can detect very small defects and can be used for the evaluation of thin materials or wires.
When you need to test a large amount of material, consider a bench-mounted hardness tester that can accommodate a larger amount of samples at one time. These units are available in a range of capacities and load strengths, and some have a programmable interface that allows for data management and reporting.
A handheld hardness tester can be easily moved around a work area and is ideal for mobile applications, such as a production line or a field inspection. These units can be loaded with various indenter sizes and loads, and can be used to calculate the hardness of a variety of metals and alloys. The most popular models are capable of converting to the Rockwell, Brinell or Vickers scales.
