How is Steel Quality Tested

Quality is an important measure of any type of product or material. Whether it be retail products or construction materials, it is important to assess their quality to see if they are fit for distribution. When it comes to construction materials, steel testing has become a standard procedure in the industry. Steel is designed to be durable, sustainable, and versatile, which is why it can be used to build a wide variety of construction projects. To ensure the steel is fit to be used in these projects, that have to be tested beforehand to check their quality.


How is steel quality tested?

The steel testing process has become increasingly diverse and comprehensive over the years, with more tests being added to ensure the strength and capabilities of the metal. There are a number of steps needed to accomplish when testing steel, from durability tests to making sure it is fit to be used in machinery. With that in mind, here are some of the most important steps taken to test the quality of construction steel.


Measuring Steel Sections

Measuring Steel Sections

One of the first steps of the steel testing process is having the steel sections measured. It is important to make sure that all sections have the same dimensions to ensure that they would not cause issues when they become used for building. Steel measurement takes into account the length, width, and weight of each section, providing the necessary information needed for further testing.


Metallurgical Testing

One of the most common steel testing procedures done is metallurgical testing. This is a process that uses a microscope to take a look at the grains of the steel sections. The grains are an indicator of the number of metals present in the steel. The proper distribution of these metal grains would ensure the steel remains durable and strong when used in building.


Compression, Fatigue, and Impact Testing

Compression, Fatigue, And Impact Testing

Also known as stress testing, the compression, and fatigue test puts steel cylinders and sections under conditions in which they have to withstand a certain weight limit. This allows you to see the breaking and cracking point of steel under different conditions. Steel sections are also subjected to different kinds of wear and tear, like corrosion, temperature, and other types of stress to see how it reacts under each condition.

Impact testing is a more extreme type of testing, as the goal is to find out if the steel section can be destroyed or cracked with one blow. This test involved the use of a pendulum and is swung on the steel. The weight of a pendulum varies depending on the size of the steel, and the impact is measured constantly to see which one causes steel to break.


Ductility Test

Along with testing to see how steel reacts to heavy impact and wear and tear, it is also tested to see how malleable and flexible it could be. A ductility test deforms the steel sections multiple times until it begins getting cracked or broken. Most steel sections have the ability to be very flexible, which is why this test pushes it to its limits to ensure that the material is versatile enough for construction.




Other than being used to build various construction projects, steel is also an important industrial material, being used for different kinds of machinery. Steel is one of the best materials for industrial machinery, as it can withstand high amounts of temperature, and can be molded and shaped into different kinds of parts. This is also the same test to assess if it is a viable material to create tools with, thus making the process more comprehensive.

This test is important, as it helps you see which type of steel is effective to use to create machines and tools, and see which ones are difficult to mold and shape. Machinery is an important component in any industry, which is why it is best to have the right type of steel for the job.


Tensile and Hardness Value

Hardness and tensile strength are two of the best qualities that steel possesses, giving it the right amount of durability that makes it last for a long period of time. Knowing the hardness and tensile value of steel can be done using a number of tests. For hardness value, steel is put through a varying set of temperatures and put through a furnace. After a number of minutes, the steep would be put on water and get analyzed. The final results would indicate whether or not it remains hard during high temperatures. For tensile value, this is measured after subjecting the steel section to heavy loads similar to a compression test. Once the steel has reached a point where it becomes damaged and deformed, the tensile value would be measured.


Key Takeaway

Steel is one of the strongest materials in the world, having the ability to withstand different weight levels and external elements. By following these procedures, you can ensure that the steel you produce offers the best quality for any type of project.
