Rockwell hardness test is one of the most common indentation hardness tests, that has been developed for hardness testing. In contrast to Brinell test, the Rockwell tester measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load).Rockwell hardness test measures the permanent depth of indentation on the material by applying a fixed load using an indenter. The smaller the indentation value, the harder is the material. The Rockwell hardness test follows the principle of the differential-depth method. Here, the indenter makes a residual depth called the indent and it is .G9645 Hardness Tester Simple in design and easy to operate, yet sensitive and accurate. The G9645 Hardness Tester was designed for measuring Rockwell Hardness values of metals and alloys of all kinds, hard or soft, whether flat, round or irregularly shaped. Different indenters and loads can be selected and the hardness values can be measured .Rockwell Hardness Tester digunakan untuk mengukur kekerasan logam mengukur ketahanan terhadap penetrasi seperti tes Brinell, tetapi dalam kasus Rockwell, kedalaman kesan diukur daripada daerah diametral. Dengan tester Rockwell, kekerasan ditunjukkan langsung pada skala yang tersambung ke komputer. Dial seperti skala benar-benar mengukur kedalaman, lulus .
The Wilson Rockwell 574 Hardness Tester Series stands out for its quality, durability, and leading Gauge Repeatability and Reproducibility (GR&R) in hardness testing instruments.

II. Theory and Principle of the Rockwell Hardness Test. The Rockwell Hardness Test uses a depth-differential method to test for hardness. A predetermined minor load is applied to the test sample, and the depth measurement is taken. Then a major load is applied to the same spot, which creates a deeper indentation.The Wilson 574 Rockwell Hardness Tester is best-in-class for Gauge Repeatability and Reproducibility (GR&R). This deadweight, workhorse tester is available in Regular, or Regular and Superficial Twin Scale models with a load range from 3-150kgf. Notable features include a high-precision depth measurement system, auto preload brake, and an .The Rockwell Hardness Test also uses superficial scales. These use lower loads and shallower indentions and are useful when a sample may be too brittle or thin for a standard Rockwell hardness test. Superficial Rockwell hardness tester: 15N, 30N, 45N, 15T, 30T, 45T, 15W, 30W, 45W, 15X, 30X, 45X, 15Y, 30Y, 45Y Polymer/Plastic ScalesRockwell Hardness Testing Reference Guide ASTM E18 contains a listing of all regular Rockwell scales and typical materials for which these scales are applicable. Use these tables in selecting the scale that is appropriate for your application. Regular Rockwell Testing. In this test method, the minor (preload) is always 10 kgf. .
The Rockwell hardness test remains the most efficient and widely used hardness test today and is recognized as one of the 20th century’s metallurgical innovations. Learn More Documents. Rockwell, Hugh M., and Stanley P. Rockwell. Patent Number 1,294,171 - Hardness Tester. 1,294,171. Bristol, CT, issued February 11, 1919.In the Rockwell hardness test, a differential-depth method, the residual depth of the indent made by the indenter, is measured.In contrast, the size of the indentation is measured in the Brinell, Vickers and Knoop optical test methods.. The deeper a defined indenter penetrates the surface of a specimen with a specified test load, the softer the material that is being tested.Ernst AT-130 Economical Regular & Superficial Rockwell Hardness Testers.
