What Is The Difference Between Steel And Stainless Steel ?

Steel and stainless steel These two metals are often understood by many people to be the same, but there is a lot of difference between these two metals. There is a huge difference between steel and stainless steel in terms of hardness, strength and ductility. Iron and carbon are mixed in normal steel. This makes it even harder and stronger.

Steel, that is, steel, is a mixture or alloy made of two metals. The two metals that makeup steel are iron and carbon. You are familiar with the strength of the iron, but perfect iron is not strong. Rather weaker than most metals. Therefore, this pure iron cannot be used for strength and hard work.

Carbon is not a metal, but when a small fraction of this carbon is added to molten iron, the material formed is completely different from carbon and is much stronger than iron, it is called steel. This means that steel is an amalgam of which the majority is iron and 0.2 percent to 2.14 percent carbon is present. In addition to carbon, chromium, manganese, vanadium and tungsten are also added as needed. All these substances together give this alloy not only hardness but also make it strong and durable.

These metals added to the iron in the required quantity make the iron hard. The more carbon is added to the iron. The harder the steel becomes.

Stainless steel is steel that does not rust. This is such a type of steel. Which is not spoiled by air, organic and inorganic acids.

This is how stainless steel was invented.

The story of the invention of stainless steel is quite interesting. In the year 1871, Harry Bearley wanted to make something for the barrel of a gun, which would not be worse than water and no chemical would have any effect on it. 

In this effort, he unknowingly made a new type of alloy, which was stainless steel. Earlier it was called rustless steel, but later it was named stainless steel. Earlier, 0.24 percent carbon and 12.8% chromium were added to stainless steel. 88% of the steel in the world is recycled. This steel can be up to a thousand times stronger than iron.
