Steel Grades 101: The Different Types of Steel

Steel is an alloy of iron and carbon, and its content can be changed to suit different requirements by adjusting the percentage of carbon and adding other elements. With different grades of steel, it can be confusing to select the right one for a specific project. In this article, we will explore the different types of steel grades, their properties, and applications.

What are Steel Grades?

Steel grade is a classification of steel based on its chemical composition, mechanical properties, and microstructure. Every grade possesses distinct characteristics and is used for specific application. Steel grades are defined by various standards organizations like ASTM and SAE.

Classification of Steel Grades

Steel grades can be broadly classified into numerous groups depending on their composition, properties, and uses.

Carbon Steel Grades

Carbon steel grades have varying levels of carbon content in them, which influence their hardness, strength, and ductility. Some of the common carbon steel grades include:

  1. Low-carbon steel (carbon content 0.1-0.3%): weldable and ductile, for use in automotive and building purposes.
  2. Medium-carbon steel (carbon content 0.3-0.6%): higher in strength than low-carbon steel, applied in engine components, gears, and axles.
  3. High-carbon steel (carbon content 0.6-1.4%): hard and strong, springs, wires of high strength, and cutting tools.

Alloy Steel Grades

Alloy steel grades have additives of chromium, nickel, and molybdenum, which improve their strength, corrosion resistance, and high-temperature capabilities. Some of the conventional alloy steel grades are:

Stainless steel (Cr content greater than 10.5%): corrosion resistant; kitchenware; medical equipment; construction in buildings.

Chrome-moly steel (Cr and Mo content): tough and creep-resistant at high temperatures, used in power plants and petrochemical applications

High-Strength Low-Alloy (HSLA) Steel Grades

HSLA steel grades have small proportions of alloying elements, which have high strength-to-weight ratios and are most suited for:

  1. Construction and bridge structural components.
  2. Car body panels and chassis parts.
