Description

Technical Field

[0001] The utility model relates to an on-site hydraulic Brinell hardness tester detection loading device. Background Art

[0002] Hardness is the local resistance of metal materials to the invasion of external objects. It is an important indicator for comparing the hardness of various materials and evaluating material performance. It is mainly used for hardness determination of materials such as cast iron, steel, non-ferrous metals and soft alloys. The Brinell hardness test is the test method with the largest indentation among all hardness tests. It can reflect the comprehensive performance of the material and is not affected by the microscopic segregation of the sample organization and the uneven composition. Therefore, it is a hardness test method with high accuracy. It is widely used in industrial fields such as metallurgy, forging, unhardened steel and non-ferrous metals.
