Describe the chemical composition of steel and the effect of carbon on the mechanical properties of steel.
Explanation of Solution
Chemical Composition of Steel:
Steel is a compound made up of carbon, iron and other elements. Due to its low cost and high strength, it can be used in construction of building, tools, ships, automobile and machines etc. The element of iron is the base metal of steel. Carbon is the major element or a hardening element that exists in the composition of steel.
Other elements like manganese, aluminum, chromium, copper, phosphorus and sulfur, silicon and vanadium etc. are also present in smaller quantities inside the steel.
When the carbon content steel is enhanced to about 0.85 percentage, then the strength and hardness will be increased proportionally. The hardness and tensile strength of steel improves with additional carbon content. In addition, brittle behaviour of steel will be augmented with carbon content.
