Which Hardness Tester Scale Is More Accurate

There are 3 common material hardness tests, Vickers, Rockwell, and Brinell, each with their different ways of testing and scale. That begs the question, which hardness tester scale Is more accurate? What is Material Hardness? Hardness describes a characteristic quality of a material, not an intrinsic physical property. In other words, you might change the hardness of a steel plate by heating or hammering it without changing its molecular composition. A material’s hardness is defined by its resistance to indentation, which can be found by measuring the depth of a permanent indentation. When you apply a known, predefined force using...

Different Types of Material Hardness

In order to build or construct anything you need to know the hardness of the material you using in your construction process. Material hardness is the ability of a material to withstand force without deformation, scratching, penetration, or indentation. Why is this important to know before your production process begins or is in the early stages? Quite frankly, if you are going to pour money into producing something or constructing something, you want to make sure it can last through different scenarios that might happen and the limitations of the very thing your are producing. Materials behave differently under different... Continue reading

Digital Hardness Testers vs Analog Hardness Testers

Hardness testing materials such as metals and alloys are essential to quality control and production of everything from steel constructions, oil and gas, automotive, etc. In order to conduct these hardness tests, the company or lab needs a hardness tester to perform the test. Now, in an age where we are all digitally connected, using this computer or that input system, you could be forgiven if you thought all hardness testers have gone digital. However, that is not the case. There are plenty of engineers and test operators that use analog hardness testers and would rather stay using one because... Continue reading

NDT testing for steel construction

Steel structures, like anything else that is manufactured, need to be tested for strength and hardness in order to make sure there are not any critical errors or failures in the structure. Non-destructive testing is an economical and effective solution to find the strength of steel structure and its joints, such as welds. This is not only a good idea for new construction, but Non-destructive testing (NDT) is also a test that allows for the evaluation of the quality of materials used for the fabrication of steel and concrete structures of existing buildings as well. Let’s explore some of the... Continue reading

Hardness Testing Blocks Guide for Buyers

Hardness Testing Blocks Guide If you have bought, or are looking to buy a hardness tester, you will also need a hardness testing block. Hardness test blocks are used to verify the hardness tester's performance and provide data in order to calibrate the hardness tester. Depending on your internal processes, you may need several test blocks and of different hardness scales. If you are a purchasing agent or engineer that has not purchased a hardness tester or hardness testing blocks, the process for determining what you need can be a bit confusing. That is why have the Buyers Guide to... Continue reading

Hardness Tester After Sales Support Considerations

Buying a hardness tester for your company is a large and important investment. Not only in terms of price, but important in terms of your manufacturing or production process. That is why Hardness Tester after sales support is an important consideration when you are choosing who to buy your hardness testers and hardness testing supplies from. Open Communication with You and Manufacturers One of the obvious considerations for after sales support is who is going to be available for questions about the hardness testers after you buy it? As much as we would like everything to go perfect right... Continue reading

Hardness Testing in the Automotive Industry

Being a leader in affordable hardness testers and hardness testing equipment, METSUCO has seen hardness testing in many different industries. One industry that which hardness testing is critical in the design and production process is the Automotive industry. Hardness Testing of ferrous and non-ferrous components to internationally recognized ASTM standards is a well-established process. Throughout the design and production process, from the frame to the engine, hardness testing is absolutely essential in quality control of the final product. Let’s look at exactly how that is the case. What is a Hardness Test? First, a quick refresher as to what is... Continue reading

Hardness Testing for Welding Joint Integrity

Hardness testing for welding joint integrity is vital for guaranteeing the structural integrity of the metal pieces being joined. It’s not always the same types of metal that are being welded together. The weld itself might be of the same material as the welded workpieces or might be of a different material (alloy) compared to the welded components. Because welding uses high heat, it can change the surrounding metal properties. At the joint of the two metals, there could be micro-cracks or delaminations that make the joint brittle. There’s no use having an ultra-strong joint if the surrounding metal is... Continue reading

Benchtop versus Portable Hardness Testers.

If you are looking to test the hardness of your manufactured part for quality testing, your need an hardness tester. METSUCO has been providing companies and universities with hardness testers and hardness testing equipment for over 30 years. In those 30 years, as we have talked to purchasing departments, engineers and others, an interesting question keeps coming up, which should we go with, a benchtop or portable hardness tester? Because of this, we want to cover Benchtop versus portable hardness testers. We are going to assume those that reading this know what a hardness test is. If you need a... Continue reading
