these are the various categories in which the steel is sold in market or are the market forms of steel.
Nails are made from iron alloys (steels).
The iron ore is refined into iron, The molten iron is then alloyed (mixed) with other molten metals, commonly chromium and nickel, along with carbon. There are different mixes to produce stainless steel with different properties. It is not truly stainless, but is stain RESISTANT and rust RESISTANT.
iron by itself is a very weak metal and it does not find any good use in the industrial applications. when carbon is added to iron as a solid solution it adds strength to it. this gives us the steel alloy. if you refer the iron-iron carbide equilibrium diagram then you will find it amazing how iron and carbon can exhibit different crystal structure this leads to the formation of a lot of variety of steel. steels can be heat treated from being very soft to being very hard and the opposite can be done as well. very tough steels can be made, very ductile steels can be made , very hard steels can be made , etc etc etc etc.,

Iron, for one...
Steels (there are many different kinds) are alloys, or mixtures, of many components. Steels are normally made mainly of Iron (a basic element, Fe) and other components such as Chromium, Molybdenum, Carbon, etc., etc. In many Stainless Steels iron is not the main alloy.
Molten Iron is not a mixture because it is still iron. Melting is a physical change meaning that the chemical makeup of the iron is not changed. Its still the element iron.
The difference is percentage of carbon, the main alloy element. Those irons containing less than 2% carbon are known as steels while those containing more than 2% carbon are known as pig iron. Pig iron is obtained from iron ore by processing it with coke in a blast furnace. This pig iron is then further processed to reduce the carbon content in different furnaces to obtain steels. These steels can be then further processed to obtain alloy steels, stainless steels by adding elements such as silicon, manganese, chromium, nickel, etc.
Nails are made from iron alloys (steels).
When molten iron cools and solidifies, this is called "fusion".
Molten iron.
Iron is used as a parent material in all steels. You can think of steels ans stainess steel types such as ferritic, austenitic, martensitic, duplex, super duplex stainless steels and many more commercial names that has many different categories. Structural steels are used in construction of buildings and bridges. iron as a major component in steel is also used in construction of piping systems in chemical and metallurgical industries as well as in reinforcements during building. These, including car manufacturing as sheet steel and good quality kitchen ware as mainly type AISI304 and AISI303 stainless steels, are major uses of iron.
