In previous posts, we have talked about the differences between the different hardness tests, such as Vickers, Rockwell and Brinell. However, we haven’t talked as much about comparing the scales and what makes them different. Here we want to go more into comparing the hardness scales themselves. First though, a quick word about testing methodology. These different scales are measured by using different hardness testing equipment and methodology, but Vickers, Rockwell and Brinell and even Shores have one thing in common, they are all measuring the hardness by indentation. Whether it’s the carbide ball of a Brinell Test or the... Continue reading

Hardness in manufacturing and engineering is defined by resistance to indentation, and it is determined by measuring the permanent depth of the indentation; which is known as a hardness test. Brinell Hardness Test was the first used and is a widely accepted hardness test. In this article we are going to dig a little deeper into explaining the Brinell Hardness Test. J.A. Brinell proposed first proposed the hardness test in 1900. Brinell's desire to have a consistent and fast means of determining material hardness grew during his involvement in several Swedish iron companies. The concept he proposed was a steel...

Non-destructive testing for Oil and Gas Industries is essential, whether it is in regard to refineries, pipelines, floating/fixed platforms, drilling rigs, tanks, vessels, heat exchangers or other equipment, the ability to test for integrities, hardness and delamination is crucial to safety and cost. Here at Metallurgical Supply Company, we carry a wide range of non-destructive testing products used by the oil and gas industry. Here, we will cover a few of the common tests that are used by testing professionals in the Oil and Gas industry. Liquid Penetrant Inspection Liquid Penetrant Inspection, also known as dye penetrant inspection, is a... Continue reading
Rockwell hardness testing is one of the more common hardness testing for metal and materials you will find out there. Yet what is exactly a Rockwell Hardness Test? What makes it different from other hardness tests? We are going to give you a break down of what is a Rockwell Hardness Test. Definition of a Rockwell Hardness Test The Rockwell test measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload. Hardness is defined as a material’s resistance to permanent indentation. Rockwell Hardness Test is one method of testing the... Continue reading
Don’t overlook this crucial difference. At Metallurgical Supply Company (METSUCO) we are often asked to provide quotes for hardness testers, calipers, micrometers, and other precision measurement tools to manufacturers and labs. Sometimes our clients know exactly what equipment or tool they are looking for, down to the specific brand and part number. But oftentimes, we ask our clients questions to help narrow down the hundreds of choices and help them get the most suitable item at the price point needed. One of the most critical questions we ask: will you be using the equipment or tool to verify or to... Continue reading
Polishing is the process or achieving the smoothest surface or best possible planeness by removing any damage remaining from grinding steps. The ultimate goal is to produce scratch and deformation free samples that can satisfy testing and clients' needs. Polishing cloths of various materials will help you achieve this goal. Polishing cloths vary on two important dimensions. You need to consider the nap, or the height of the fiber, and the stiffness or resiliency of the fiber. For most applications, polishing cloths are used in conjunction with diamond suspensions, diamond pastes, and other powders and liquids of varying grain sizes.... Continue reading
Demand is increasing for Non-Destructive Testing. Bloomberg put out a Press Release in February 2020 that stated “The global non-destructive testing market size is expected to reach USD 24.3 billion by 2027, expanding at a CAGR of 6.5%, according to a new report by Grand View Research, Inc. The market is anticipated to witness significant growth over the forecast period.” This is not really surprising to us. Now the big industry reports will break down the main things like where the growth is happening, companies driving the growth, etc. What we want to do is break down why the demand... Continue reading

What are important after-sales support considerations for hardness testers? Continue reading
Hardness testing is widely used in a variety of industries including auto manufacturing, aerospace, oil and gas and many others. It tests the hardness of materials, which is critical for product development and keeps from having costly and embarrassing mistakes. If your company is looking to purchase a new hardness tester, you have a choice to make: digital hardness tester or analog hardness tester. Between the two, there are some definite benefits of a digital hardness tester. Now, first off, in this technology age, some would ask why would anyone consider analog anyways? Why is this even being discussed? Yet,... Continue reading
