About Insitu Hardness Testing Services

The term hardness, as it is usedin industry, may be defined as the ability of a material to resist permanentindentation or deformation when in contact with an indenter under load.Generally a hardness test consists of pressing an indenter of known geometryand mechanical properties into the test material. The hardness of the materialis quantified using one of a variety of scales that directly or indirectlyindicate the contact pressure involved in deforming the test surface. Since theindenter is pressed into the material during testing, hardness is also viewedas the ability of a material to resist compressive loads. The indenter may be spherical(Brinell test), pyramidal (Vickers and Knoop tests), or conical (Rockwelltest). In the Brinell, Vickers, and Knoop tests, hardness value is the loadsupported by unit area of the indentation, expressed in kilograms per squaremillimeter (kgf/mm2). In the Rockwell tests, the depth of indentation at aprescribed load is determined and converted to a hardness number (withoutmeasurement units), which is inversely related to the depth.

Hardness testing is perhaps thesimplest and the least expensive method of mechanically characterizing a materialsince it does not require an elaborate specimen preparation, involves ratherinexpensive testing equipment, and is relatively quick. The theoretical andempirical investigations have resulted in fairly accurate quantitativerelationships between hardness and other mechanical properties of materialssuch as ultimate tensile strength, yield strength and strain hardeningcoefficient and fatigue strength and creep. These relationships help measurethese properties with an accuracy sufficient for quality control during the intermediateand final stages of manufacturing. Many times hardness testing is the onlynondestructive test

alternative available to qualifyand release finished components for end application.

Hardness Testing is often usedto verify the effectiveness of the heat treatment applied to actual castings.Its general correlation with the tensile strength of many ferrous alloys allowsa rough prediction of tensile strength to be made.

Advanced Onsite Hardness Testing

Our service delivers insitu hardness testing for steel and other metals using portable devices with cutting-edge digital interfaces. Designed for accuracy, each test aligns with the Leeb Rebound principle, allowing immediate results in HLD, HB, HRB, HRC, HV, or HS scales. This technology is engineered to maximize convenience and reliability on manufacturing floors, workshops, and field locations.


Comprehensive Data Handling

Test results are stored internally for up to 500 readings, ensuring extensive record-keeping reliability. Outputs are accessible through USB or RS232 ports, permitting seamless transfer to external systems for analysis and reporting. The service supports both automatic and manual calibration to maintain testing precision.


Optimized for Diverse Conditions

Our instruments function efficiently across varying temperatures (0-50C) and voltages (110-230V, 50 Hz). The portable and lightweight design allows effortless onsite deployment, while the rechargeable Li-ion battery secures extended operational capability. Multiple material modes cater to different alloys and steel grades, ensuring versatile testing.
