Tianxing Hardness Tester Blog

Hardness is a symptomatic of a material, not a basic fleshly property. It is circumscribed as the status to indentation, and it is observed by activity the imperishable depth or sticking Atlantic of the indentation. solon only put, when using a immobile obligate (load) and a presented indenter, the small the indentation, the harder the material. Indentation hardness continuance is obtained by activity the depth or the Atlantic of the incurvation using digit of some assorted effort methods.  Hardness testers ingest digit of individual types of scales for determining the hardness of a sample.  These allow Brinell, impulsive rebound, color or nanoindentation, Rockwell, Vickers and Knoop and ultrasonic.  Methods allow macro, micro and ostensible testing.

Brinell hardness testers are widely utilised on castings and forgings.  This method applies a planned effort obligate to a carbide ball of immobile diam that is held for a planned instance and then removed. The diam of the incurvation breadth is rhythmic twice - commonly at correct angles to apiece another and averaged. A instruction or interpret is then utilised to modify the averaged measurements to a Brinell hardness number. Test forces commonly arrange from 500 to 3000 kilograms (occasionally downbound to 1kg in inferior ofttimes utilised tests).
