Skip to content +1 847-295-6500; . Wilson Brinell . The Brinell hardness number (BHN or HBW) describes the hardness of a material. The higher the number, the harder the material. The Brinell hardness test involves pressing a small metal ball into the surface of the test material with a known amount of force. The resulting indentation is then measured and converted into a hardness number.Brinell Hardness Test. The Brinell hardness test is named after its inventor, Johan August Brinell. It involves applying a constant load or force to a spherical indenter made of hardened steel or carbide onto the surface of the material being tested. The indentation diameter is then measured optically.

Large indenter for average hardness: Not suitable for very hard materials, large indentations: Large parts, castings, forgings: . The Brinell hardness test measures material hardness by determining the diameter of an indentation made by a hardened steel or carbide ball under a specific load. A load, typically ranging from 500 to 3,000 kgf, is .The oldest of the hardness test methods in common use on engineering materials today is the Brinell hardness test. Dr. J. A. Brinell invented this test in Sweden in 1900. . As in the Vickers test, a diamond indenter with a specific geometry is impressed into the specimen surface with a known, calibrated force for a duration of 10–15 sec . In the standard method of the Brinell Hardness Test, we use 250 to 500 kg of load for soft material and 500 to 3000 kg of load for hard material such as steel and iron. In the standard method of the test, we use a ball indenter of 10mm diameter.

Sama halnya dengan hardness test dengan Brinell, karena pengukuran dilakukan secara manual maka terdapat kemungkinan terjadinya kesalahan ukur. Kesalahan itu mungkin terjadi ketika pemfokusan objek pada layar, peletakan alat ukur pada objek dan .Certified Hardness Test Blocks are a requirement as a reference material for any type of hardness testing. Home; Products. . Brinell Hardness Test Blocks — ASTM E-10 and ISO 6506 . It is primarily employed to prevent breaking in brittle materials and to make it easier to measure the hardness of thin layers. The indenter used in the Knoop .However, it is essential to consider the material's thickness relative to the indenter size. As a general guideline, the material should be at least ten times thicker than the indentation depth to ensure accurate results. If the material is too thin, alternative hardness testing methods, such as Rockwell or Vickers, may be more appropriate .
Compared to the other hardness test methods, the indenter used in brinell makes the deepest and widest indentation, so that test averages the hardness over a wider amount of materials which will accounts for multiple grain structures and any irregularities in the uniformity of the material. The Brinell hardness number is defined as the ratio of . ASTM E384: This standard is for hardness testing on a micro-scale, and therefore includes the Vickers and Knoop hardness tests. ISO 6506: This standard mirrors ASTM E10, as it contains the standard method for measuring the Brinell hardness of metals.

The test provides numerical results to quantify the hardness of a material, which is expressed by the Brinell hardness number – HB. The Brinell hardness number is designated by the most commonly used test standards (ASTM E10-14[2] and ISO 6506–1:2005) as HBW (H from hardness, B from brinell and W from the material of the indenter, tungsten .The diameter of the indentation made on the material’s surface by a spherical indenter—typically a hardened steel ball—is used to calculate the Brinell hardness number (HB). Calculation of Brinell Hardness testing. Brinell hardness testing is used to measure the hardness of materials, particularly metals and alloys.
It is an optical method. This means that the size of indentation left by the indenter is measured to determine the hardness value of a test specimen.

Engineering ToolBox - Resources, . Brinell Hardness Number vs. Material; Material Brinell Hardness Number; Soft brass: 60: Mild steel: 130: Annealed chissel steel: 235: White cast iron: 415: Nitrided surface: 750: Steel Hardness versus Strength.
In the original test proposed by Brinell, the load L is expressed in kilogram force. If L is measured in N (SI system), Eq. 1 should be divided by 9.8065. The full test load is applied for a period of 10–15 s. Two diameters of impression at right angles are measured (usually in the range 2–6 mm), and the mean diameter value is used for calculating the Brinell hardness .The Brinell hardness number is designated by the most commonly used test standards (ASTM E10-14[2] and ISO 6506–1:2005) as HBW (H from hardness, B from Brinell, and W from the material of the indenter, tungsten (wolfram) carbide).Hardness testing standards have been set by various organisations such as The American Society for Testing and Materials (ASTM) and The International Organisation for Standardisation (ISO), prescribing specific varieties of a hardness test determined by factors such as the type of indenter, applied force, and procedure of force application.
