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
Across many different industries such as oil and gas, aerospace, auto manufacturing, and commercial construction, just to name a few, there is a need to have the hardness of the materials tested. This is to make sure the product or material in question will not critically fail down the line. In order to test a material’s hardness, there is a device called a hardness tester. A hardness tester is an instrument used to measure just how hard a material is. This is typically done by assessing the impact that penetration has on the surface of an object by a rounded...

Manufacturers and quality control managers do not always have the luxury of cutting materials into a sample and taking it into a lab for examination. A different solution is needed for field testing materials. Many manufacturers use portable hardness testers, which offer several other advantages. What is Hardness Testing? Hardness testing is used in mechanical and materials engineering to test the hardness of a material, such as a metal. Hardness tests analyze a specific material and its properties and ascertain whether or not a given material is the best fit for the job. Hardness tests are used on multiple kinds... Continue reading
Metal hardness tests are crucial to engineers, metallurgists, and manufacturers in many industries, from automotive, to oil and gas, and aerospace to name a few. Performing a hardness test is a critical step in qualifying metal parts and determining the various properties of a specific metal. A metal passing or failing a test will help dictate product design, production process, and innovation. There are many different metals and alloys and different applications of those materials. Different test scales are used to assist engineers in selecting the appropriate metals and hardness for their specific application. The three most widely used today... Continue reading
