The 3831Digital Rockwell Hardness Tester can be used directly to measure the most popular regular Rockwell hardness scales and it can quickly convert that hardness value into HB, HV, HLD, HK and many other scales.The Starrett 3814 accurately measures hardness of materials in Rockwell .The Starrett 3814 accurately measures hardness of materials in Rockwell hardness A, B, and C scales. Heat-treated steels are tested using a 120 diamond indenter in the C-scale (HRC 20-70).The clamping ability is an inherent part of this Rockwell hardness tester and provides the user with the ability to clamp and hold parts in place prior to testing with up to 240 foot pounds (325 Nm). By clamping instead of using jack screws or cutting specimens, the test accuracy is improved and the testing time is decreased.
Rockwell hardness testing is popular due to its ease of operation including the absence of optical measuring equipment, a range of alloys may be measured, and readings can be obtained in a matter of seconds with both .
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 .Here Stanley Rockwell and founder Charles H. Wilson introduced the Rockwell hardness tester, an industry standard. Later, Wilson became the home of the legendary Tukon line of micro-indentation testers – renowned for Knoop and Vickers testing.Rockwell testing falls into two categories: Regular Rockwell testing (e.g., C and B scales) and Rockwell superficial testing (e.g., 30 N and 30 T scales). High Rockwell hardness numbers represent hard materials and low numbers soft materials. d 2 www.wilsoninstruments.com Fundamentals of Rockwell Hardness Testing
In the Rockwell hardness testing, the indenter applies the first load to the test piece. The indent is then measured, and the value obtained is used for the base calculations. This first load is removed, and another heavier load is applied to the indenter on the test piece. . No special skill is required in their maintenance. .
The Rockwell hardness (HR) is then determined from the residual indentation depth, along with a few other factors (see below). In hardness testing according to Rockwell, the total test force is applied in two steps. This is intended to eliminate effects from the roughness of the specimen surface (e.g., grooves on the specimen) as well as .Get more done with the Wilson RH2150 Rockwell Hardness Tester. Through its vast capability of testing scales and large load range from 1 to 187.5 kgf, the RH2150 caters to diverse applications.Bring material right to your bench to measure its hardness. These testers use a carbide indenter to take accurate Rockwell hardness readings every time. They come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. With a durable metal body, these testers stand up to many environments, from heat treat facilities to workshops to inspection labs. ASTM recommends annual maintenance and verification of a Rockwell tester and more frequent verification under heavy use or extreme conditions. Verification should be performed by an accredited verifying agency and the report should follow and reference ASTM E18 Rockwell test method. Hardness testing is an important and useful tool in materials .
Rockwell 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 method, as defined in ASTM E-18, is the most commonly used hardness test method. You should obtain a copy of this standard, read and understand the standard completely before attempting a Rockwell test. The Rockwell test is generally easier to perform, and more accurate than other types of hardness testing methods .Preventive maintenance scheduled at a time that suits your business will help ensure you get the most out of your materials testing equipment and minimize disruption to your operations.

The Rockwell hardness testing method fulfilled every requirement. After 100 years, it’s still the best metal strength test method. The Rockwell C scale is also the most precise way to report metal strength used in industrial machine .
Maintenance, maintenance and precautions of Rockwell hardness tester. When transporting the Rockwell hardness tester , the weight and indenter must be removed, and an anti-vibration rubber pad should be placed between the indenter seat and the sample table; the original packaging should be restored for long-distance transportation.
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 Scales
