Set includes six files and a chart to convert to Vickers scale. It is an economical way to determine the hardness of steel on the Rockwell C-scale.Handles are marked with Rockwell hardness values. If a file can scratch your material, then your material is softer than the file. If a file cannot scratch your material, then your material is harder than the file. Quality 101:Rockwell Hardness Test
- Types of Rockwell TestsRockwell ScalesPrinciple of The Rockwell TestScalesRockwell hardness values are eed as a combination of a hardness number and a scale symbol representing the indenter and the minor and major loads. The hardness number is eed by the symbol HR and the scale designation. There are 30 different scales. The majority of applications are covered by the Rockwell C and B scales for testing steel, brass and other metals. However, the increasing use of materials other than steel and brass, as well as thin materials, necessitates a basic kWhat is Rockwell Hardness Number - Rockwell Scale Rockwell Hardness Number Rockwell Scale 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
Rockwell Hardness Test Definition - United Testing SystemsThe Rockwell Hardness test also uses superficial scales. These use lower loads and shallower indentions 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
The Rockwell hardness number is eed as a combination of the measured numerical hardness value and the scale letter preceded by the letters, HR. For example, a hardness value of 80 on the Rockwell A scale is reported as 80 HRA. Analytical Information. Regular Rockwell Hardness Testing- Measures the bulk hardness of the material. There are Steel Hardness Conversion TableRockwell HRB Vickers HV N/mm²; 3000kg 10mm Ball 150kg Brale 100kg 1/16" Ball . Diamond Pyramid 120kg. Tensile strength (Approx) Reference table:Steel Hardness conversion chart. Since the various types of hardness tests do not all measure the same combination of material properties, conversion from one hardness scale to another is only an approximate process. The Rockwell ScaleThe Rockwell scale characterizes the indentation hardness of materials through the depth of penetration of an indenter, loaded on a material sample and compared to the penetration in some reference material. It is one of several definitions of hardness in materials science.
Each Rockwell scale is an arbitrarily defined range of numbers from 0 to 100 covering a specific range of material hardness. Although, theoretically, the entire scale can be used for hardness testing, there are practical limitations on the range of testing for many of the Rockwell scales.
