How to measure the hardness of curved samples
In the field of hardness measurement, the shape and surface characteristics of the sample will directly affect the accuracy of the measurement results. Especially for samples with curvature (such as round bars, pipes, etc.), if the conventional platform is used for measurement directly, the results will often be biased. So, how to correctly measure the hardness of such samples? This article will explain it in detail for you.

LABTT Hardness Tester Indenter Replacement Guide
The hardness tester is a key device for material hardness testing, and the indenter is the core component of the hardness tester. Its status is directly related to the accuracy of the test results. In actual use, the indenter will inevitably wear and crack, so it is particularly important to replace the indenter in a timely manner.

The differences and applications of various hardness testers
According to the Vickers hardness tester, hardness is a performance indicator that measures the degree of softness and hardness of a material. There are many methods and principles for hardness testing, and the measured hardness values and meanings are also different. The commonly used methods are the static load indentation hardness test, which includes Brinell hardness (HB) and Rockwell hardness (HRA), HRB，HRC)、 Vickers hardness (HV), which represents the ability of a material's surface to resist the pressure of hard objects. The Leeb hardness (HL) and Shaw hardness (HS) belong to the rebound hardness test

Notes on the calibration of hardness testers
Before calibrating the HR-150 Rockwell hardness tester, do not use a hardness block to measure the reading error of the hardness tester. First, determine whether the working state of the verified hardness tester is in normal working state. This requires attention to the following issues

Discussion on troubleshooting methods for hardness tester faults
There are many types of hardness testers, and the commonly used ones in industrial and mining enterprises and research institutions are mainly metal Rockwell, Brinell, Vickers, and microhardness testers. Among them, metal Rockwell and Brinell hardness testers have a simpler structure compared to metal Vickers hardness testers. The repair of common faults is not very difficult. Below is an introduction to common troubleshooting of metal Vickers hardness testers.

Introduction to Vickers hardness tester
The Vickers hardness tester was first proposed by British scientist Vickers. Under a load of 49.03~980.7N, a square conical diamond with a relative angle of 136 ° is pressed into the surface of the material
