Grainger Rockwell Hardness Tester For Sale
When it comes to evaluating the strength and durability of metal parts, hardness testing is an important step in the process. A rockwell hardness tester for sale can help you determine how much force is required to make an impression on the surface of a sample, which helps you assess its strength and integrity. Grainger offers a wide selection of hardness testing instruments to fit the needs of your business.
There are several different types of hardness tests that can be used to evaluate metals, including the Rockwell scale and Brinell test. The type of hardness testing you choose depends on the size and shape of the sample and your application.
The Rockwell hardness test is the most popular method for determining hardness. It uses a diamond cone or steel ball to penetrate the sample and measures the depth of penetration and the quality of the impression. This method is most commonly used for hardened steel and other hard metals. However, it is not recommended for use below 785 N/mm2.
In addition to Rockwell hardness testers, Grainger also offers Brinell and Vickers hardness testers to suit a variety of applications. The Brinell testing method uses a spherical indenter to distribute pressure evenly, which can lead to more accurate results than the Rockwell test. This method is also more effective for assessing soft-bearing materials, making it the preferred choice for testing castings and forgings.
If you need to test small precision parts, thin material or wires, consider a Vickers hardness tester. This method is more precise than the Rockwell testing method and can measure both a spherical indentation and a dimple. This type of testing is non-destructive, so it can be performed on bulky or awkwardly shaped samples without damaging them.
Ultrasonic hardness testing is another non-destructive method that can be used to evaluate the hardness of a sample. It can be used on flat surfaces and is able to detect internal defects. This method can be used for metals, ceramics and other materials.
