Next-Level Hardness Testing with the Telebrineller Brinell System

Testing a material’s hardness is an important method for evaluating its resistance to deformation. This process involves measuring the indentation on a material’s surface and translating it into a hardness value. Hardness test is an essential part of quality control during manufacturing and is used to compare materials fitment for a range of applications, from cutting and grinding metals to rubbers designed to absorb shocks. This is where the Telebrineller Brinell Systems comes in handy!

The hardness test, however, is not without its challenges. As surface condition significantly influences hardness readings, precise and repeatable results are dependent on proper surface preparation, usually involving grinding and polishing. With older testing machines, it can also be challenging to measure the size of indentations, especially on non-flat surfaces. Advanced technologies, such as cameras and software, have improved the precision and ease of use of modern models.

This blog will explore hardness testing in depth, with a focus on our advanced Telebrineller Brinell Hardness Testing System. This system offers simplicity, precision, and versatility, suitable for a wide range of materials. It is our goal to provide insight into how the Telebrineller system improves test efficiency and accuracy by exploring how it works.

What is Hardness Testing?

metal before hardness test

Hardness testing, an essential part of material science, measures how well a material resists permanent distortion, penetration, indentation, and scratching. From an engineering perspective, this property correlates with wear resistance under different conditions such as friction, erosion, and exposure to elements such as steam, oil, and water. Tests assess how much pressure a material can withstand before altering its shape by applying a specific, known force to its surface.

Choosing materials for specific environments and uses requires an understanding of their hardness. For example, in environments where small particles may cause material wear, the hardness determines how well the material resists being deformed or indented. Brinell, Rockwell, Vickers, and Knoop test methods are suitable for different purposes and materials, providing diverse means of measuring hardness.

Brinell Hardness Testing

Since we will focus primarily on this method of hardness testing today, it’s necessary to gain a deeper understanding. Brinell hardness testing, widely used in industrial applications, determines metal hardness based on the size of indentions caused by specific indenters. Developed by Johan August Brinell in 1900, this method uses a tungsten carbide ball as an indenter. Brinell Hardness Number (BHN or HBW) is calculated by measuring the depth of the indentation, which is inversely related to the hardness of the material.

This test involves pressing a tungsten carbide ball into a test material using a predetermined force. Testing machines consist of levers, weights, hydraulic dashpots, and plungers that apply forces ranging from 1 kg to 3000 kg. Indenters typically come in four sizes: 1 mm, 2.5 mm, 5 mm, and 10 mm.

There are several standards governing Brinell hardness tests, including ASTM E10, ISO 6506, and JIS Z 2243. Through these standards, testing for hardness is consistently and reliably performed across an array of industries.

The Brinell test method measures the hardness of rough samples, applies high loads, and can be applied to a wide range of metals, providing reliable results. It does, however, have limitations, including potential measurement errors due to optical instruments, surface preparation requirements, and inapplicability for cylindrical surfaces or materials above 650 HBW 10/3000.

Testing hardness, particularly using the Brinell method, is a cornerstone of assessing materials’ durability and suitability. We focus on Brinell Hardness Testing in this blog because the Telebrineller Brinell Hardness Testing System uses this method, making the data it provides highly accurate.

Introducing the Telebrineller Brinell Hardness Testing System

Telebrineller Brinell Hardness Testing System

Our Telebrineller Brinell Hardness Testing System has been recognized as a superior quality assurance solution. This welding crew-specific system was designed based on over fifty years of field experience and metallurgical expertise. In addition to its portability, the complete system, encased in a durable case, weighs under ten pounds, making it easily transportable and ideal for measuring hardness in any environment.

Telebrineller’s operation is remarkably simple. An easy hammer blow is used to measure the impressions, followed by a basic calculation on the included computer. Brinell Hardness Number (BHN) can be determined quickly and accurately without specialized training.

A calibrated test bar ensures precision to within 0.05 millimeters of the labeled BHN, ensuring the accuracy of the system. By complying with the National Standards Institute’s rigorous requirements, this calibration is meticulously carried out. With its weather-proof design and robust components, our Telebrineller system guarantees accurate measurements in tough field conditions regardless of weather conditions.

A Telebrineller Brinell Hardness Testing System also meets ASTM E10 standards, ensuring compliance with other global standards. As a result of its ability to comply with established standards, the system is known for its reliability and suitability for many types of industrial uses.

Telebrineller System Operation Principle

Telebrineller Brinell Hardness Testing System is based on a straightforward principle. The first step is to select a test bar that closely matches the expected hardness of the specimen by Brinell Hardness Number (BHN). For consistent accuracy, the BHN of the test bar should be within + or – 15% of the BHN of the specimen, and the materials should be similar. Non-ferrous materials tested with carbon steel bars should be corrected for impact errors using designated correction factors. After selecting the test bar, it is inserted into the Telebrineller instrument, which is then precisely positioned on the specimen.

Standard Telebrineller Testing System Kit with Accessories

Telebrineller Brinell System Accessories

Telebrineller’s hardness testing instrument comes with a comprehensive standard kit that includes all the components you need to conduct an effective test. This kit includes a test bar, an anvil, and a molded rubber head. This helps to ensure stability and non-skid contact with the test bar. Also included in the unique construction is a steel impression ball embedded at the base of the rubber head, which is crucial for creating accurate impressions on both the test bar and specimen.

With a hammer weighing between two and five pounds, a sharp strike is applied to the anvil to operate the system. As a result of this design, the impact force, regardless of its magnitude, is evenly distributed between the test bar and the specimen. By uniformly transmitting force via the impression ball, precise impressions are created, which are used to determine the hardness levels of materials. Further, the system includes a spacing bar with a spring catch and button that enables the test bar to be adjusted for each test.

Accuracy of Telebrineller Brinell Hardness Testing System

Our product is highly acclaimed for its accuracy, which makes it the best choice for Brinell Hardness Testing. Telebrineller Brinell tester exemplifies precision in material testing, anchored by Telebrineller Test Bars. Precision-ground to a 9/16″ square finish, these bars are meticulously crafted from various carbon steel alloys to ensure a uniform hardness of plus or minus 2% of the Brinell Hardness Number (BHN) etched on each bar.

With the King-Scan, an advanced computerized calibration system, accurate measurements of impression diameters are made to determine BHN. By ASTM Standard E10 guidelines, BHN values are rounded to the nearest standard at a .05mm interval. The National Institute of Standards has set these standards. It is noteworthy that the Telebrineller system’s accuracy depends on the relative hardness between the test bar and the specimen. It can consistently achieve +/- 5% accuracy when the test bar’s BHN is within 15% of the specimen’s BHN.
