There are different types of steel and they are arranged according to the physical and mechanical properties for the application. Various grading mechanisms are used for this task and thus, steels are being graded based on the properties. It’s pretty much how we are graded based on our performance in each subject, steel have their subjects as their qualities. And these qualities are what we’re going to talk about today.
Of course, all materials will have imperfections as much as you like it to be perfect. If we’re talking about steel, these flaws take the form of small cracks. So, if steel have the required level of toughness, the cracks won’t spread throughout the product and it would withstand any pressure. But, if ever the steel can’t take it anymore, the product will get dismantled and that’s why grading steel is important. Imagine a building falling into pieces because they used the wrong grade of steel. Some grades of steel are used even with surface grinding and some are for construction, just like I said.
When steel is being pressured and force is transferred into the material, ductility will be the key factor to prevent the destruction of the material. Ductility measures the degree of how the material can endure the pressure or stress and reduce the risk of cracks circulating around the material. There are several ways to test the ductility of steel and if they found it to be high enough, it might even make it to the construction industry as steel supplies Australia. Ductility is also how flexible the material can be. This is definitely a key factor for the medical and food sector. If it’s flexible enough, this material can be made use as stainless steel and change the shape by applying force into it without resulting to cracks. So it can be turned into forks, spoons, utensils, and other things.
Tensile Strength and Hardness
The tensile strength is how much pressure the material can take before getting destroyed. Unlike ductility, this means being totally destroyed. In terms of human, incapacitated while in ductility, you just get knocked out. That of a steel is high enough thus the reason why it’s widely used for construction. If the hardness of this material, there would also be an added benefit of prolonging the lifespan of this alloy for a much better user experience.
I can’t stress enough the importance of knowing the qualities of steel, especially when you use steel product all day long. This will avoid unnecessary incidents that is caused by unfamiliarity about steel.
