Employment as of 2014 was 149 000 people employed in iron and steel mills and.
Iron and steel industry raw materials.
Steel alloy of iron and carbon in which the carbon content ranges up to 2 percent with a higher carbon content the material is defined as cast iron.
Key raw materials needed in steelmaking include iron ore coal limestone and recycled steel.
The indian ministry of steel always focuses on the maintenance of the iron and steel industry for the development of infrastructure as well as the nation s economic progress.
But are you aware that this affluent industry depends on a constant supply of raw materials like iron ore coal flux fuel water refractories scrap iron ferro alloys and more to function properly.
In 2014 the united states was the world s third largest producer of raw steel and the sixth largest producer of pig iron.
The industry produced 29 million metric tons of pig iron and 88 million tons of steel.

In this articles you ll get to know different raw materials used in making iron and steel.
Recycled steel sometimes called scrap steel is one of the industry s most important raw materials.
Most iron and steel in the united states is now made from iron and steel scrap rather than iron ore.
Steel is an alloy of iron with typically a few percent of carbon to improve its strength and fracture resistance compared to iron.
The basic raw materials are.
Today it is estimated that the global steel industry used about 2 billion tonnes of iron ore 1 billion tonnes of metallurgical coal and 575 million tonnes of recycled steel to produce about 1 7 billion tonnes of crude steel.
The integrated steelmaking route based on the blast furnace bf and basic oxygen furnace bof which uses raw materials including iron ore coal limestone and recycled steel.
It is described as any mineral substance that contains enough iron which makes its smelting a viable proposition i e an iron content if less than 20.
By far the most widely used material for building the world s infrastructure and industries it is used to fabricate everything from sewing needles to oil tankers.
The united states is also a major importer of iron and steel as well as iron and steel products.
Many other additional elements may be present or added.
Stainless steels that are corrosion and oxidation resistant need typically an additional 11 chromium because of its high tensile strength and low cost steel is used in buildings infrastructure tools ships.
