Grainger Rockwell Hardness Tester For Sale

Rockwell hardness tester for sale is a tool used to measure the hardness of metal or other materials by applying a force to a diamond indenter that creates an impression on the surface. The depth of the impression is measured to determine the material’s hardness level.

There are a few different types of hardness testers on the market, each with its own advantages and disadvantages. The most common type is the Rockwell test, which uses a penetrating diamond cone or steel ball to make an impression on the surface of the sample. This type of testing is suitable for most samples, but it’s not the best choice for extremely hard metals like tungsten or titanium. The Rockwell test also takes longer to perform than other methods and requires a clean, flat surface on the sample.

Another popular type of hardness tester is the Brinell test, which measures the diameter of the indentation made by a steel ball forced into the sample. This type of testing is able to handle very large, rough samples that are difficult to test with other methods. However, the Brinell test can produce inconsistent results and is more likely to cause distortion on the sample’s surface than other tests.

A final type of hardness tester is the Knoop test, which uses a narrow, diamond-shaped indenter to create an impression on the sample. This type of testing is fast and precise, but it’s only suitable for very light test loads. The Knoop method can be used to measure the hardness of many different materials, including carbon steel, alloy steel and cast iron.

Grainger offers a variety of high-quality hardness testers for a range of applications, from traditional bench-mounted models to portable ultrasonic testing units. Choose a Rockwell tester to measure the hardness of metals using the Rockwell scale, or opt for a Brinell test for larger parts like castings and forgings. For smaller, precision parts or wires, consider a Vickers tester that can be used to assess the hardness of soft-bearing metals and carbides. For non-destructive inspection, look for a Leebs tester that can evaluate the hardness of materials without contacting them directly.
