Classification of various hardness of steel
The code for metal hardness is H. According to different hardness test methods, the conventional representations include Brinell (HB), Rockwell (HRC), Vickers (HV), Leeb (HL), Shore (HS) hardness, etc., among which HB and HRC are more commonly used. HB has a wider range ...Read more -
Hardness test method of fasteners
Fasteners are important elements of mechanical connection, and their hardness standard is one of the important indicators to measure their quality. According to different hardness test methods, Rockwell, Brinell and Vickers hardness test methods can be used to test the ...Read more -
Application of Shancai/Laihua Hardness Tester in Bearing Hardness Testing
Bearings are key basic parts in the field of industrial equipment manufacturing. The higher the hardness of the bearing, the more wear-resistant the bearing is, and the higher the material strength is, so as to ensure that the bearing can withs...Read more -
How to choose a hardness tester for testing tubular shape samples
1) Can Rockwell hardness tester be used to test the hardness of steel pipe wall ? The test material is SA-213M T22 steel pipe with an outer diameter of 16mm and a wall thickness of 1.65mm. The test results of Rockwell hardness tester are as follows : After removing the oxide and decarburized la...Read more -
Operation methods and precautions for the new XQ-2B metallographic inlay machine

Several common tests of Vickers hardness tester
1. Use Vickers hardness tester of welded parts (Weld Vickers hardness test) method: Since the microstructure of the joint part of the weldment (weld seam) during welding will change during the formation process, it may form a weak link in the welded structure. The...Read more -
Select various hardness testers for testing based on material type
1. Quenched and tempered steel The hardness test of quenched and tempered steel mainly uses Rockwell hardness tester HRC scale. If the material is thin and HRC scale is not suitable, HRA scale can be used instead. If the material is thinner, surface Rockwell hardness scales HR15N, HR30N, or HR45N...Read more -
Relationship between Brinell, Rockwell and Vickers hardness units (hardness system)
The most widely used in production is the hardness of press-in method, such as Brinell hardness, Rockwell hardness, Vickers hardness and micro hardness. The obtained hardness value essentially represents the resistance of the metal surface to the plastic deformation caused by the intrusion of for...Read more -
