How do you determine the hardness of ductile materials?
Hardness of ductile materials can be determined by following methods..... 1) Brinell Hardness Test 2)Vickers Hardness Test 3)Rockwell Hardness Test 4) Scratch hardness test
What is the difference between Hardness and Harden-ability of steel?
There are some differences between hardness and hardenability. Hardness is the surface property of material to give resistance to the penetration or plastic deformation and it is measured by one of the tests......Rockwell hardness test,Brinell hardness test and Vicker hardness test. On the other hand,hardenability is defined as the ability how the material would be hardened and it is measured by Jominy hardenability test.
What is fatigue what are various test used for evaluating hardness of any material?
progressive damage due to repeated cyclic tensile loadings. Brinell test, Rockwell test
How do you compare tool steel grades?
Tool steels are compared to each other. They are usually measured by toughness, hardness and wear resistance. The toughness is detemined by an Charpy impact test. The hardness is measured by a Rockwell hardness tester and reported as HRC or RC. The wear resistance is measured by a number of tests that measured the amount of material removed from the original size after a repetitive movement against an abrasive material. These figures are then gathered and presented on a chart. The grades are then compared with one another based on these three properties. See the links below for more information on comparing tool steels.
What is the initial load in Rockwell hardness test?

What is the difference between vickers hardness test and brinell hardness test?
In Vickers hardness test the for used is much lighter than the force used in Rockwell hardness test, The Rockwell hardness test is the considered to be the most routinely used technique to measure the hardness of materials because of its simplicity and because it does not require specific skills in order to perform it.
What is the of significance initial load in Rockwell hardness test?
the answer is 10KGF

How to identify a hardness of a unidentified material?
To identify the hardness of an unidentified material, you can use a hardness test such as the Mohs scale, Vickers hardness test, or Rockwell hardness test. These tests involve applying a specific amount of force to the material's surface and measuring the indentation or scratch it creates to determine its hardness.

What test is used to dertemined if one material is harder than another?
The Rockwell hardness test is commonly used to determine the hardness of materials by measuring the depth of penetration of an indenter under a specific load. This test is widely used in manufacturing and engineering to compare the relative hardness of different materials.
What is Rockwell C?
Answer Rockwell C is a method to measure the hardness of a metal object. The hardness of the metal is a direct correlation to its strength properties: i.e., Tensile Strength. The scales can be found in any engineering or matierals reference books. A test devise is used to strick a metal object with a small pointed hammer. The size of the dimple is compared to a chart to give you the Rockwell C hardness value. There are 3 charts for measuring hardness: A scale, B scale and Cscale. Rockwell C is for the hardest of metals such as very high strength steel. Rockwell A is for much softer materials including something as soft as clay, I believe. During manufacture, a hardness test will be performed to ensure that the finished product meets the design engineer's criteria to ensure the part.
What is the difference between brinell and rockwell hardness tester?
Brinell hardness tester uses a ball to apply a specified load on the material surface, measured by the resulting indentation size. Rockwell hardness tester uses a diamond cone or steel ball to penetrate the material, and hardness is calculated based on the depth of penetration. Brinell is better for softer materials and larger test areas, while Rockwell is more versatile and provides different scales for various materials.
What is the unit of hardness?
The unit of hardness is typically expressed in terms of Rockwell (HRC), Vickers (HV), or Brinell (HB) scale depending on the specific test method used. Hardness is a measure of a material's resistance to deformation or indentation.
