Different kind of steel

Steel, on the basis of its nature and components, can be classifi~d into five kinds as under:
1. CARBON STEEL:
Most of the kinds of steel ,in use are classified ,as 'carbon steel', The proportion of carbon in different kinds of carbon steel but Manganese proportion is not more than 1 .65 per cent nevertheless, the proportion of Silicon is 0.60 per cent and copper is also 0.60 per cent. In other words, Manganese, Silicon and Copper are mixed in Carbon Steel.Carbon steel is used .for making springs for bed mattresses, structure of the ships, buildings structure, motor cars body and machines.
2. ALLOY STEEL:
Different kinds of Alloy steel are being made in which different proportions of various metals are mixed to change their properties so that they could be used for desired purposes. 20 per cent in the world production of steel is constituted by Alloy Steel. If a certain proportion of Vanadium and Molybdenum is mixed, the steel becomes more hard and strong having the capability of bearing the shocks and vibrations. This is the reason that his kind of alloy steel is used for making the Excel and gear of motor vehicles.
If high proportion of manganese is mixed in steel, steel becomes more hard and is used for mining machines electric machines and heavy machinery. If Nickel is mixed,steel, it becomes very hard to be used for boll bearing armourd plates.By 'mixing chromium, steel is can into Stainless Steet
and used in man~fact!Jring such which can be rusted like milk bottles&nd,airplanes etc.
If Tungsten and Cobalt is mixed in steel, it can be used in making iron cutting blades like blades of lath machines. By mixing Silicon and Copper: common steel is made.
3. HIGH STRENGTH lOW-ALLOy STEEL:
 " This kind of steel is the most modern invention amongest all the kinds of steel in use'which is a1so termed as HSLA is called  'low alloy' because the cheap metals are mixed in this kind of steels.But this steel is more strong than t·carbon steel. For example, loading trucks and vehicle are made' of this steel because the walls of the vehicle arEin weight but stronger that the Carbon Steel.
4. STAINLESS STEEL:
Nickel, Chromium and other elements are mixed, Stainless Steel. Stainless·steel is not only strong but retain its glittering and is save from rusting and moisture Gases and acids do not a.ffect the stainless steel. Sta steel is used for making chemical plants and petre refininy pipes. Apart from it, it is also used for airplane:
space capsules. Surgical instrunents are also mE' stainless steel. In the home kitcher,s, food processing and for cutlery making, stainless steel is utilized because this metal is not only rust proof but it can also be cleaned easily.
5. TOLL STEEL:
Toll steel is fabricated in the bands of different tool and implements. It is also used in machines generated by energy. Molybdenum, Tungsten and such other metals mixed in Toll Steel which provide iron extra ord strength, hardness and power of resistance.
