Steel is the most common metal alloy in the world.At the basic level it has iron and different levels of carbon.Because both iron and carbon have been well-known since ancient times, steel has been produced in one form or another since, well, before the birth of Christ.Some of the very earliest steel was made in the eastern regions of Africa, around 1400 BCE.
The main constituents of steel is iron with little bit of carbon.While one of the most universally used thing is carbon there are other metals that proffer a different element to it.Steel is well-known for its strength, which is given to it precisely by the alloying elements.
The modern steel industry produces steel through the use if what is called the basic oxygen furnace.In these furnaces, molten iron has pure oxygen blown through it, lowering the levels of impurities in the iron.The main idea of adding fluxes is for this purpose as well.The main advantage to this process, other than a high-quality product, is its speed.
As a result of the changes that have taken place in the making of steel a lot of alloys are now being produced.One can make and mould the steel as per ones individual needs when added with tungsten and chromium.The array of properties that steel can be given by the addition of alloys is evidenced, for example, in the fact that two things as different as samurai swords and automobiles are both made from steel alloyed by other metals
The usual steel has a combination of 0.5% manganese and 0.5% silicon considered as carbon steel and anything else is just an alloy steel.
General Purpose Steel
A General Purpose Steel has good weldability, forming and extruding chrematistics.The automobiles and buildings are made with this usual form.
Steel that has excellent welding ad bending properties, perfect for structural applications is your General Purpose Low Carbon Plate Steel.Also, this has good machinability and formability, used mostly in automotive camshafts and similar applications.
There is use of more carbon plates for better intensity.It has optimal combination and strength, good weldability and an almost perfect material for retaining after machining.
Lastly in this category, you have Medium Carbon Steel, often used for bolts, studs and shaft parts.It is also known for its high strength and hardness.
Hot Rolled Carbon Steel
It is low carbon steel at the first place.It is very good for solidity, malleability and welding as well.
It is also called as the Low Carbon, High Manganese Steel.This has good machinability; case hardening is deep and is uniform.There is nothing more bendable than this due to its non-crack feature that it has.
Medium Carbon - Direct Hardening
This is a steel that is lot better than the Low Carbon Steel called the Intermediate Carbon.It is simply used for studs, bolts etc.To achieve greater strength and hardness, it is used in a rolled condition.Through this, it becomes perfect for hammer forging processes.Its usability can be seen in gears, shafts, axles, bolts and studs etc.
Improved machinability and better heat treatment response (surface hardness is deeper and more uniform) than plain carbon steels. This has functionality in the making of gears, shafts, axles, bolts, studs, pins and lot more.
There is nothing more proficient than the fast cutting steel in the screw stock. A broad range of strength and toughness is attainable through variations in heat treatment.It is often used in forging, tubing and fittings.
Steel Waters Run Deep
.This is very useful for us in so many things that we use such as cars and construction products, refrigerators and washing machines, cargo ships and surgical scalpels.This gets used in every thing that we use everyday like.
