ABSTRACT Steel is one of the most commonly used materials spanning across various industries such as the building, automobile, machinery, tool-making, and weapon industries. It is an alloy consisting of iron and carbon, with the addition of other materials necessary for its desired use. Generally, steel is seen as a material of high strength, low weight, durability, flexibility, as well as highly resistant to corrosion. The carbon content of steel is often varied, resulting in various steel grades. Due to its inexpensiveness and ability to be altered to suit different necessities, many professionals look to this material as an input of production. This report examines the mechanical properties of steel, beginning with its chemical composition. It shows steel in terms of its lattice structure, and how alterations of this structure result in the various grades of steel. Furthermore, the process of heat treatment is defined and applied to the production of steel for various uses. Finally, it defines the physical and mechanical properties of steel as a general material, and also closely examines multiple categories of steel, analyzing the properties in terms of the composition of the material.

INTRODUCTION Over the past decades, steel has become one of the most common materials used around the world, Annually, more than 1.3 billion tons is produced, used in various industries as components of buildings, infrastructure, tools, ships, automobiles, machines, appliances, and weapons. Steel is an alloy which is generally identified by various grades which are defined in regards to the ratio of carbon and iron content. An alloy is a partial or complete solid solution of one or more elements in a metallic matrix whose properties usually differ from those of the component elements (1) . In this case, steel is manufactured by mixing iron and carbon in a specific ratio, in which the carbon may range from 0.2 percent to 2.14 percent of the total mass. However, there are various other elements that
