Different Types of Steel and Their Uses
INTRODUCTION OF STEEL:
The different between cast iron and steel is different amount of their carbon contents. Alloys in which the iron mixes with carbon and also other element to become steel. And high carbon steel percentage should be not greater than from 1.5%
TYPES OF STEEL
We have different types of steel which are some of these.
(1) Mild Steel
(2) Medium carbon Steel
(3) High Carbon Steel
MILD STEEL
In mild steel where the amount of carbon is from 0.15% to 0.30% so this kind of steel Is called mild steel. And also we called this kind of steel Low carbon steel or Soft steel.
Properties Of Mild Steel.
This steel Is ductile and malleable and very soft.
This steel is more elastic than cast iron.
It can be permanently used.
Specific gravity of this steel Is 7.8.
This steel does not affected from saline waters.
It can easily weld and riveted.
Use of mild steel
This kind of steel is mostly used in construction works. From this (mild steel) take a circular bar of 25mm , 12mm , 8mm etc. so these bars are used in concrete work to resist the tensile stress.
MEDIUM CARBON STEEL
In this kind of steel we used the amount of carbon from 0.30 to 0.60%. when we used this percentage of carbon in steel so this kind of steel is called Medium carbon steel.And This kind of steel is is stronger than low carbon steel, and it is more difficult to form in welding and also in cutting.
Medium Carbon Steel
In this kind of steel we used amount of carbon from 0.30 to 0.60%. when we used this percentage of carbon in steel so this kind of steel is called Medium carbon steel.And This kind of steel is is stronger than low carbon steel, and it is more difficult to form in welding and also in cutting.
Properties of Medium Carbon Steel
This kind of steel so hard from low carbon steel/mild steel.
Its too much difficult in cutting.
It does not bend easily.
Use of Medium carbon steel
The use of Medium carbon steel is require of high tensile strength and ductility. And this kind of steel used to make different thing with choice. But we have to use used amount of carbon from 0.30 to 0.60% so it will be able to make any thing with our choice.
This kind of steel so hard from low carbon steel/mild steel.

It does not bend easily.
Use of Medium carbon steel.
The use of Medium carbon steel is require of high tensile strength and ductility. And this kind of steel used to make different thing with choice. But we have to use used amount of carbon from 0.30 to 0.60% so it will be able to make any thing with our choice.
HIGH CARBON STEEL
In this kind of steel (High carbon steel) we used amount of carbon from 0.60% to 1.5%. When we used this percent of carbon so this kind of steel is called High carbon steel.
Properties of High Carbon steel.
This kind of steel is more difficult in welding.
it is too much easier to harden and to temper.
This kind of steel Is using permanent.
Use of High Carbon Steel
High carbon steel is used to make axes, Knife, Swords and scissors for cutting tools.
