What is STEEL? Types of Steel? Carbon Steel Types Detail Explanation.

Steel is an alloy of iron and carbon and, sometimes, other elements such as chromium. Because of its high tensile strength and low cost, this material is best used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, and weapons.

Steel is graded as a way of classification and is often categorized into four groups—Carbon, Alloy, Stainless, and Tool.

Carbon Steels only contain trace amounts of elements besides carbon and iron. This group is the most common, accounting for 90% of steel production. Carbon Steel is divided into three subgroups depending on the amount of carbon in the metal: Low Carbon Steels/Mild Steels (up to 0.3% carbon), Medium Carbon Steels (0.3–0.6% carbon), and High Carbon Steels (more than 0.6% carbon).
Alloy Steels contain alloying elements like nickel, copper, chromium, and/or aluminum. These additional elements are used to influence the metal’s strength, ductility, corrosion resistance, and machinability.
Stainless Steels contain 10–20% chromium as their alloying element and are valued for their high corrosion resistance. These steels are commonly used in medical equipment, piping, cutting tools, and food processing equipment.
Tool Steels make excellent cutting and drilling equipment as they contain tungsten, molybdenum, cobalt, and vanadium to increase heat resistance and durability.
