Metal has been used in industrial application from a very long time. There are many different characteristics of metals that make them very useful for various different applications in industry and domestic fronts.
Without the use of metals, it is not possible to make an industry work properly, efficiently and smoothly. The various industries that use metals include automobiles, industrial machinery, construction, and so forth. There are different properties that make metals the best for industrial usage.
In industries, it is important to make sure that the quality of the metals is tested before they are used for any sort of application. The testing of metals must be done using proper testing instruments so that accurate measurement results and data could be obtained. Here are some of the tests that must be performed on the metals for best quality assurance.
Tensile strength tests
The tensile strength of a metal is the property of a metal that gives it its elastic properties. With high tensile strength, it is more likely that the metal will be able to bear more tensile stress or tension during its usage in actual working conditions. A tensile test is performed using a tensile testing machine which gives accurate data about the tensile strength of the metal.
Rockwell Hardness Test
The Rockwell hardness test is used for testing the hardness that is offered by a metal against any sort of indentation that is caused due to an indenter under a particular load. The test is performed using instruments called as Rockwell Hardness tester.
Flexural test
The flexural test is performed to assess the ability of a metal to resist the metal fatigue that develops when the metal is subjected to varying and repeated loads.
Corrosion Resistance Test
Corrosion of metals takes place when they are subjected to direct contact with open environments. When the metal comes in contact with oxygen and moisture, it oxidizes, and a layer of metal oxide is formed on it. This layer is called rust. Rusting is a phenomenon that makes the metals vulnerable, weaker and degrades the quality of the metal as well. In order to make metal resistant to corrosion, first of all, it is important to test the effects of the corrosive environment on the metal so that necessary measures to prevent corrosion could be taken. This is done using a salt spray chamber. To protect the metals from corrosion, there are various actions such as painting, plating, coating, galvanization, amalgamation and so forth. This helps in enhancing the durability of the metal products.
With proper quality testing, it is possible to attain the best performance of the metal products in industrial and domestic usage.
