The Basic Types of Steel Metal

If you were to ask the American Iron and Steel Institute (AISI), they would tell you that steel can be categorized into four basic groups according to their individual chemical compositions. These four groups include 1) Carbon steel, 2) Alloy steel, 3) Stainless steel, and 4) Tool steel. All steel is composed of both iron and carbon, but vary in type depending on certain physical, chemical, and environmental properties, all of which are determined by the amount of carbon and any additional alloys.

Categories of Carbon Steel

Carbon steel can be further categorized into three groups, which are low carbon, medium carbon, and high carbon. Low carbon, also called mild steel, is one of the largest categories of carbon steel, and generally contains anywhere from 0.04% to 0.30% carbon content. Medium carbon generally contains anywhere from 0.31% to 0.60% carbon content, as well as a range of 0.60% to 1.65% of manganese content. High carbon steel is informally known as “carbon tool steel” and contains 0.61% to 1.50% carbon content. It is difficult to manipulate, and becomes very brittle when heat-treated.

Stainless Steel

Stainless steel contains added alloys that make is extremely resistant to corrosion in comparison to carbon and alloy steel. This is why it is commonly used in the medical/surgical industries, appliance industry, hardware manufacturing industry, food processing/handling industry, architectural industry, and more. It contains both carbon and iron, as mentioned before, but stainless steel generally contains other alloys as well, such as Chromium (Cr), Molybdenum (Mo), or Nickel (Ni). 

Alloy Steel

Alloy steel also contains carbon, since all steel contains both carbon and iron. But alloy steel also contains a marginal number of additional elements, such as Nickle (Ni), Chromium (Cr), and Manganese (Mn). This type of steel is popular and commonly used due to their wide availability, economical costs, ease of processing, and quality mechanical properties. In comparison to carbon steel, alloy steel is more responsive to mechanical and heat treatments. Heated alloy steel comes in wither annealed or normalized.

Tool Steel

Tool steel is a general term to describe a variety of steels that retain high-hardness and abrasion-resistance properties. Specific applications for tool steel include stamping, extrusion, dies, cutting, mold-making, or impact applications such as hammering.
