Hardness Gauge

As you know, the main prerequisite for doing any work is to have accurate information about that subject. In the discussion of selection, checking prices, buying, and getting to know more about the types of hardness testers and their functions, the following materials are included for you, dear visitors of the specialized website of DamaTajhiz (an official member of the heating and air conditioning equipment sellers' union), with the help of this Tips You can choose and buy suitable hardness testers in bulk for your living or work environment with enough information.

Types of hardness testers and their user manual

Hardness is a material characteristic that takes on different meanings according to the user's experience. In metallurgies, the metal's hardness is resistant to plastic deformation compared to the penetration of an object that sinks into them. So we will conclude that hardness is the expression of the resistance to deformation. In the case of metals, it is a measure of their resistance to temporary or permanent deformation. Hardness is not a homogeneous and fixed property of the material, and it may be different for a particular piece at two points. There are different methods, including hardness testing by Reumer, Faupel, elastic hardness test, abrasion or cutting resistance test, and indentation resistance test (which has three Brinell, Rockwell, and Vickers methods). Join us in introducing and checking the performance of hardness testers in the rest of this article.

Basic methods of hardness measurement of metals

• Hardness measurement by the Rheumer method
• Fogel hardness tester

Hardness measurement by the Rheumer method

In this method, the edges of two metal prisms are pressed together.

Fogel hardness tester

In this method, two semi-cylindrical metals are pressed together, and the size of the expanded contact surface is determined.

Hardness measurement methods

• Elastic hardness test
  Abrasion or cutting resistance test
  Indentation resistance test

Hardness measurement by the elastic hardness test method

A microscope is used in this method. This way, a diamond pyramid or prism with a certain weight, which is released from a certain height, returns to the top after hitting the surface. The returned height of the diamond-shaped prism or pyramid is measured and determines the amount of energy absorbed by the metal. This method is also called dynamic and was named by a person named Shor.

Hardness measurement through wear or shear resistance

In this method, they use scratching. This way, minerals and other materials are used for scratching according to their strength. The abrasive mineral's depth and width will indicate the material's hardness. Frederick Moss mentioned this method. Below you can see the hardness table of minerals.

Hardness measurement through indentation resistance

In this method, they use the penetration of a sinker in part. This way, the material is fixed on the surface, and the sinking object enters the material under a fixed and specific load. The material's resistance against the penetration of the sinking object, the depth of penetration, and the area of the created effect will indicate its hardness.

Different methods for testing indentation hardness

• Brinell hardness test (BRINELL)

• Rockwell hardness test

• Vickers hardness test (VICKERS)

In the hardness tester group of the reference site and store of temperature equipment, see the information and prices of hardness testers and analyzers of different brands for review and selection.
In addition to a valid business license from the heating and air-conditioning trade union, DamaTajhiz has an electronic trust symbol. It started operating its store site in 2013 in Tehran's head office.
