The WEBSTER Hardness Testers are portable instruments that can perform on-site hardness testing on aluminium alloys, brass, copper and soft steel. A quick and easy test, the hardness value can be read out directly from the indicator with a simple clamp.
The Rockwell method is the most universal because it uses both a penetrating diamond cone and a penetrating steel ball to measure the hardness of a material. The diamond cone can only be used on hardened steel and hard metals. It is not recommended below 785 N/mm² hardness.
A study demonstrated that the effect on the HRC scale indicated a tilt angle of one degree between the specimen surface and the indenter's axis could result in a 5% error in hardness. Tilt angle should never surpass 2 degrees to guarantee accurate testing.
The most common type of hardness test is the Rockwell test. The Rockwell test encompasses a set of tests for different hardness ranges. The Rockwell B (HRB) scale is used for aluminum and structural steels (softer materials) while the Rockwell C (HRC) scale is used for high carbon alloy steels (harder metals).
By comparing the portable hardness testers, it was found that the hardness tester TH170 was more accurate for Brinell hardness test (inaccuracy -3.90 %), Rockwell hardness test (-4.81 %) and Leeb hardness test (+0.38 %); the hardness tester TH1100 was more accurate only for Vickers hardness test (-1.75 %).
