So I need your help in this guys please, I also need to know the uses of it. I need it for a project so please help me out here guys, thanks.
Steel made from scrap can be every bit as good as that made from ore but much, like rebar, is whatever it turns out to be. Depends on what the steel mill wants to make. Rebar is scrap melted down and each batch is different. It's analyzed only to guarantee a minimum strength usually nothing else. As a result it's not a good idea to torch cut, weld or forge rebar, there is no way to determine what the hardness/temper will be after heating. Might be OK might be very brittle. Other steel made from scrap could be analyzed and processed to be any quality desired same as virgin steel.
There are many varieties of steel. They each have a recipe of other elements added to liquid iron, depending on the characteristics needed. Carbon is one of the main ones. There are many uses for steel, again the type of steel varies with its uses.

The first link has this: To make Steel, Iron Ore is refined into iron and all the carbon is burned away using very high heat (Bessemer). A percentage of Carbon (and other trace elements) are added back to make steel. The uses for steel? You can look at the second like for that. But here is a list from the pedia link provided: Iron and steel are used widely in the construction of roads, railways, infrastructure, and buildings. Most large modern structures, such as stadiums and skyscrapers, bridges, and airports, are supported by a steel skeleton. Even those with a concrete structure will employ steel for reinforcing. In addition to widespread use in major appliances and cars. Despite growth in usage of aluminium, it is still the main material for car bodies. Steel is used in a variety of other construction materials, such as bolts, nails, and screws.[67] Other common applications include shipbuilding, pipeline transport, mining, offshore construction, aerospace, white goods (e.g. washing machines), heavy equipment such as bulldozers, office furniture, steel wool, tools, and armour in the form of personal vests or vehicle armour (better known as rolled homogeneous armour in this role).
