Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to its high elastic modulus, yield strength, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world.
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). 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.

Steel is made by smelting through either a blast furnace or an electric arc furnace. The first method uses iron ore and a type of coal called coke, which has had its impurities removed. This gets fired by air and doused with lime to create the metallic material needed.
Steel is an alloy of iron and carbon containing less than 2% carbon and 1% manganese and small amounts of silicon, phosphorus, sulphur and oxygen. Steel is the world’s most important engineering and construction material.
At its core, steel is an alloy primarily composed of iron and carbon, with varying amounts of other elements introduced to achieve specific properties. This alloying process allows for the creation of a material with remarkable strength, durability, and versatility.
