TYPES OF STEEL & STEEL GRADES CHART

February 11, 2021 | Categorised in: Uncategorized

Steel is one of the most useful materials in the world. In the simplest context, steel is composed of iron and carbon, but in actuality, steel isn’t so simple. The concentration of carbon and iron or the addition of other elements affects steel’s properties and strength, which aids in steel’s usefulness for an endless variety of end uses.

In this resource, you’ll find steel classifications, usages, and types, along with our ASTM Steel Grade chart at the bottom. Let’s start by explaining the four main types of steel categories.

The four types of steel

Steel is a highly versatile material that can be used in various industries. Steel is typically categorized into types based on various criteria such as chemical composition, physical properties, and usage. Here are the four most common types of steel:

Carbon steels
Alloy steels
Stainless steels
Tool steels

Carbon steel

Carbon steel has a higher concentration of carbon than other types of steel (up to 2.5% carbon), which adds to carbon steel’s strength. Carbon steel is commonly used to make construction materials, tools, automotive components, and more.

Types of carbon steel

Carbon steel is organized into three main categories:

Low carbon steel (or mild steel) is one of the most common types of carbon steel, with a carbon content between 0.04% and 0.30%.
Medium carbon steel has a carbon range of 0.31% to 0.60%, and a manganese content ranging from .060% to 1.65%.
High carbon steel, also known as tool steel, has a carbon range between 0.61% and 1.50%.

Alloy Steel

Alloy steel is made by combining carbon steel with one or several alloying elements, such as titanium, copper, chromium, aluminum, manganese, silicon, and nickel. This produces specific properties that are not found in standard carbon steel.

Stainless steel

Stainless steel is a type of steel alloy that contains a minimum of 11% chromium, which helps the material resist corrosion. It is widely used in applications where corrosion resistance is essential, such as kitchen utensils and cutlery.

Tool steel

Tool steel is a type of steel alloy whose hardness, resistance to abrasion, and ability to retain shape at increased temperatures make it a popular choice for hand tools and machine dies.

Steel classifications

Steel can also be classified by several different factors, including:

Composition (carbon range, alloy, stainless, etc.)
Finishing method (hot rolled, cold rolled, cold finished, etc.)
Production method (electric furnace, continuous cast, etc.)
Microstructure (ferritic, pearlitic, martensitic, etc.)
Physical strength (per ASTM standards)
De-oxidation process (killed or semi-killed)
Heat treatment (annealed, tempered, etc.)
Quality nomenclature (commercial quality, pressure vessel quality, drawing quality, etc.)

Steel numbering systems

The steel industry uses two major numbering systems to classify steel grades, the American Iron & Steel Institute (AISI) and Society of Automotive Engineers (SAE) systems. Both the AISI and SAE systems primarily use four-digit numeric codes to identify a material’s base carbon or alloy steel; however, some select alloy steels have five-digit codes.

All carbon steels start with a one (1) in both the SAE & AISI systems. Carbon steels are then further subdivided into four categories by their underlying properties. The four categories are:

Plain carbon steel: 10xx series (containing 1.00% Mn maximum)
Resulfurized carbon steel: 11xx series
Resulfurized and rephosphorized carbon steel: 12xx series
Non-resulfurized high-manganese: 15xx series (containing up to 1.65% Mn)

The first digit on all other alloy steels (under the SAE-AISI system), are classified as follows:

2	Nickel steels
3	Nickel-chromium steels.
4	Molybdenum steels.
5	Chromium steels.
6	Chromium-vanadium steels.
7	Tungsten-chromium steels.
8	Nickel-chromium-molybdenum steels
9	Silicon-manganese steels and various other SAE grades

The second digit of a series typically indicates the concentration of the major element in percentiles. The last two digits of a series indicate the carbon concentration.

Steel grades & standards

According to the World Steel Association, there are over 3,500 different grades of steel. At its core, steel is composed of iron and carbon, but the amount of carbon, level of impurities, and additional alloying elements all contribute to what grade steel is classified. Each steel grade has its unique properties and typical end-use. Below are the common grades of steel and their uses as determined by the American Society for Testing and Materials (ASTM).

ASTM steel standards

ASTM International is a nonprofit organization that brings together experts from various industries to develop and maintain a vast collection of voluntary consensus standards. These standards cover a wide range of aspects, including material composition, mechanical properties, testing methods, and specifications for various steel products.
