That’s why these standards formulate tables for conversion process, with test load and hardness ranges. Here are the hardness tables and conversion charts for you. + 86 755 61301520The 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). Refer to the “Hardness Comparison Table” below for converting different hardness values of steel. Hardness Conversion Chart. . When HB>450 or the specimen is too small, the Brinell hardness test cannot be used and the Rockwell hardness measurement is adopted instead. This involves using a diamond cone with a 120° apex angle or a steel .Reference Table: Steel hardness conversion chart - all values approximate. Brinell Hardness HB Rockwell HRC Rockwell HRB Vickers HV N/mm² : 800: 72 : 780: 71 : 760: 70
A chart is then used to convert the averaged diameter measurement to a Brinell hardness number. Test forces range from 500 to 3000 kgf. A Brinell hardness result measures the permanent width of indentation produced by a carbide indenter applied to a test specimen at a given load, for a given length of time.Metallic materials — Brinell hardness test — Part 4: Table of hardness values 1 Scope This part of ISO 6506 gives a table of the Brinell hardness values for use in tests on flat surfaces. 2 Determination of the Brinell hardness for testing on flat surfaces See Table 1. Table 1 Ball indenter, D mm Force-diameter ratio, 0,102 × F/D2 30 15 10 .
The Brinell hardness test was developed by the American Henry Brinell, who created the first tester in 1873. This is a widely accepted method in the field. The ASTM’s Brinell hardness test standard is used by alloy and metal suppliers and users, and it’s a basic requirement for all hardness testing equipment.

A well structured Brinell hardness number reveals the test conditions, and looks like this, "75 HB 10/500/30" which means that a Brinell Hardness of 75 was obtained . 1.5 At the time the Brinell hardness test was developed, the force levels were specified in units of kilograms-force (kgf). Although this standard specifies the unit of force in the International System of Units (SI) as the Newton (N), because of the historical precedent and continued common usage of kgf units, force values in kgf units are provided for information .
Brinell Indentation Diagram. 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. 1.5 At the time the Brinell hardness test was developed, the force levels were specified in units of kilograms-force (kgf). Although this standard specifies the unit of force in the International System of Units (SI) as the Newton (N), because of the historical precedent and continued common usage of kgf units, force values in kgf units are provided for information .
Table of contents: Brinell hardness number; Calculating Brinell hardness| Brinell hardness formula; . In the Brinell hardness test, we use a small ball (the indentor) made of tungsten carbide or steel to penetrate the material's surface, leaving a hemispherical indent. From the load/pressure on the indentor and the diameter of the hole it .Brinell Hardness Tester holds significant importance in today's industrial landscape, where understanding material properties is crucial for ensuring product quality, reliability, and performance. This test reveals vital information .
brinell to rockwell hardness chart
Brinell Hardness Test. The Brinell test uses a larger spherical indenter, usually made of steel or carbide, and applies a heavy load to the material. The diameter of the indentation is measured to calculate the Brinell hardness number (HB). . Please check the below “Vickers to Brinell Hardness Conversion Table” for the reference: 2 .Brinell [HB] is one of the most common units used for listing the hardness of steel materials. The test is done with a 10 mm steel ball pressed with 3000 Kgf (6,614 Lbf). Common values for machined materials range from 100 HB for .The typical relationship between indentation diameter and HB is provided in Table 2.The standard ball for Brinell testing is 10 mm (±0.005 mm) in diameter and should have a minimum hardness of 850 HV.When balls of smaller size are used, the load as well as the ball size should be specified along with the test result.The typical relationship between indentation diameter and HB is provided in Table 2.The standard ball for Brinell testing is 10 mm (±0.005 mm) in diameter and should have a minimum hardness of 850 HV.When balls of smaller size are used, the load as well as the ball size should be specified along with the test result.
Note: The numbers in brackets are hardness values which lie outside the definition range of the standardized hardness testing methods, but are practically used as approximate values in many cases. 1): The Brinell hardness values up to 450 HB were determined with the steel ball as the indenter, the higher values with the carbide ball.布氏硬度试验（Brinell scale）是压入硬度试验之一种，其测量值用HB或BHN表示。. 该试验最初由瑞典 工程师 Johan August Brinell（1849年-1925年）于1900年提出。 布氏硬度是第一个被广泛用于工程学及冶金学的标准化硬度试验。 此试验方法因压痕较大和对待测材料损伤明显，应用受到 .Hardness test methods and hardness conversion tables Introduction. Hardness is a surface property where indentation, scratching or wear is resisted. . The hardness figure is followed by a code indicating the test method. The Brinell and Vickers methods have been used historically in the UK, the Brinell method for softened steels, and Vickers .
Hardness conversion tables for Rockwell, Brinell, Vickers. Welcome visitor you can login or create an account . Home Wish List (0) My Account Shopping Cart Checkout The HRB scale typically is used for soft materials such as aluminum and brass alloys. It uses a 1/16-in. ball indenter with a 100-KG test force. Brinell Testing. Brinell testing normally is used for larger, heavy-walled pipe. Because the Brinell test is not a depth-measuring technique, it is more forgiving. When the Brinell hardness test cannot be used, such as when the material’s HB value is greater than 450 or the sample size is too small, the Rockwell hardness test is used instead. This test involves pressing either a diamond cone with a top angle of 120° or a steel ball with a diameter of 1.59 mm or 3.18 mm into the surface of the tested .Hardness Conversion Chart. Hardness testing measures the resistance of a material to deformation, or hardness, and is an important physical property in manufacturing as it directly correlates to material strength. A variety of hardness testing methods are available including the Brinell and Rockwell tests. Thus, the Hardness Conversion Chart .
