Standard Rockwell Hardness Tester

HRH-150

Standard Rockwell Hardness Tester is a widely used instrument for measuring the hardness of materials. It operates based on the Rockwell hardness testing principle, which involves measuring the depth of penetration of an indenter into the material under a specific load. The Rockwell hardness scale provides a numerical value that represents the material’s resistance to indentation. Standard Rockwell hardness testing is commonly employed in industries such as manufacturing, metallurgy, and quality control to assess the hardness and mechanical properties of materials. The test results obtained from the Standard Rockwell Hardness Tester can help in material selection, process control, and product evaluation.

Description

Standard Rockwell Hardness Tester – HRH-150

Standard Rockwell Hardness Tester is a widely used instrument for measuring the hardness of materials. It operates based on the Rockwell hardness testing principle, which involves measuring the depth of penetration of an indenter into the material under a specific load. The Rockwell hardness scale provides a numerical value that represents the material’s resistance to indentation. Rockwell hardness testing is commonly employed in industries such as manufacturing, metallurgy, and quality control to assess the hardness and mechanical properties of materials. The test results obtained from the Material hardness measurement can help in material selection, process control, and product evaluation.

The testing procedure involves applying an initial minor load to the indenter, followed by a major load. After the major load is removed, the depth of the indentation is measured and used to determine the Rockwell hardness value based on the specific Rockwell scale being used (e.g., Rockwell B or Rockwell C).

Components of Hardness testing instruments

Frame:The sturdy frame holds all the components of the tester and provides stability during the testing process.
Anvil:The anvil is a flat and rigid surface on which the material being tested is placed. It ensures proper support and alignment of the specimen.
Indenter:The indenter is a diamond or a hardened steel ball that is pressed into the material under a specific load. The Standard Rockwell Hardness Tester can accommodate various types of indenters, such as a diamond cone or a steel ball, depending on the hardness range of the material being tested.
Load Application System:The load application system applies a pre-determined load to the indenter, which creates the indentation on the material’s surface. The load is typically applied using a lever or a hydraulic system.
Dial Gauge or Digital Display:The tester is equipped with a dial gauge or a digital display that provides a readout of the indentation depth. This measurement is used to determine the Rockwell hardness value.

Rockwell hardness test involves applying a specific load to an indenter, usually a diamond cone or a hardened steel ball, and measuring the depth of the indentation created. The test is performed using a Rockwell hardness tester, which consists of a frame, an anvil, an indenter, a load application system, and a dial gauge or digital display. Rockwell hardness scale is a system used to measure the hardness of materials, specifically metals and alloys. It provides a numerical value that represents the resistance of a material to indentation or penetration by a specific indenter under a given load.
