What Is Steel Grade?

The classification of steel products is typically represented by a combination of letters, chemical element symbols, and Arabic numerals to denote its name, purpose, characteristics, and production process.

This system has been developed over many years by various national standardization organizations, such as the European EN standards, American ASTM standards and AISI standards, Japanese JIS standards, Chinese GB standards, and international ISO standards.

Steel is generally classified based on the following criteria:

  • Chemical composition: including carbon steel, low alloy steel, and stainless steel
  • Smelting method: including open hearth steel, converter steel, and electric furnace steel
  • Processing technology: including hot rolled steel and cold rolled steel
  • Product shape: such as thick plates, thin plates, strips, pipes, and profiles
  • Deoxidation methods: including killed steel, semi-killed steel, and boiling steel
  • Microstructure: including ferritic steel, pearlitic steel, and martensitic steel
  • Strength level: for example, the tensile strength of grade C in the ASTM A420 standard ranges from 515 to 655 MPa
  • Heat treatment process: including annealing, quenching, tempering, and thermomechanical processing.

Steel is often categorized based on its carbon content into the following three groups:

  • Mild steel, including AISI 1005 to AISI 1026, IF, HSLA, TRIP, and TWIN steel
  • Medium carbon steel, such as AISI 1029 to AISI 1053
  • High carbon steel, such as AISI 1055 to AISI 1095.

Moreover, based on the European standard classification, steel can be further divided into the following categories:

  • Non-alloy steel, such as ENDC01-DC06; S235; S275
  • Alloy steel, such as 2CrMo4 and 25CrMo4
  • Stainless steel
  • Tool steel, such as EN1545; AISI/SAE W110; EN 1.2436, AISI/SAE D6
  • Plate and strip
  • Electrical steel plates and strips, such as EN0890 and EN 1.0803.

It’s worth noting that sometimes, special steel grades may have different characteristics due to variations in standards.

For instance, 34CrMo4 is defined by both DIN and EN. The EN standard includes six subgroup specifications, while the DIN standard has different specifications.

These steel specifications outline changes in tensile properties that result from various thermomechanical treatments.
